This is our AvP2 Alien Walkthrough Guide which includes missions from the alien campaign in 2001’s Aliens versus Predator 2 game for PC.
Level 1: Birth
Date: November 23, 2230
Time: 10:13 PM
Incident: -1 Day, 07.00 hours
Location: Cargo ship. Western landing. Primary Operations Complex (POC) — LV-1201
The Mission Objectives:
1. Escape the cargo vessel.
2. Find an isolated host.
After the cut-scenes, you start your mission within a cargo ship called the Aurora. If you explore for a while, you’ll find a shaft. Crawl up there and you’ll see a tunnel with a pole in the centre. Go through the tunnel until you see some marines. Continue through until you see some more marines below. Go to the end and turn lefty and you’ll see a small hole in a grill. Go through that and you’ll be in the next room. This room will be full of crates and just outside the room will be two scientists chatting about something. Go into the vent that’s nearest to the bars. You’ll get to a small room with some steam. Try to avoid the steam and go through the hole at the top of the next fencing. Carry on through the steam. Follow the route until you get to a room with a bolt of electricity. Go right to dodge the electricity and go into the tunnel. Use your other vision so you can see where you’re going.
You’ll be soon above the ceiling with two scientists talking about something. When they stop talking jump down in the hole onto the desk below. Now run out the door and into the corridor. Go right from the door and keep looking up at the ceiling for a vent. When you see it at the end of the corridor, crawl up the wall and into the vent. Wait until you hear them go away and run towards the broken door and go through the crack in the door. Go right after the door and you’ll find someone sleeping in a chair in a confined room. Use your pouncing ability, leap onto his face and get ready for the next part of the level. After the cut-scene you will start inside the chest as a Chestburster. Bite your way through his chest and watch the next cut-scene.
Nearby the man will be an open window. Jump out of that onto the platform. Use the other small platforms to get down to the ground. Keep working your way around the crates hiding so no one sees you. Wait for the man to walk away and go hide behind the crates near the marine. Do not attempt to look at them because they will see you straight away. Wait until the marine leaves and go out from the crates and onto the ally. Cross to the other side of the ally and follow it around and around the corner. Wait until the marine disappears and go right into the ally and follow it down to the bottom. When you get to the end keep to the right and wait for the marine to come. An animal will cry out and the marine will come running. When he’s gone past you, turn right into the next ally. Keep going and at the end hide behind the tall object and wait for the next marine to pass. Once he’s passed, go towards the crates. Soon enough a vehicle will arrive next to you.
Let the truck go past and stay behind it. Wait for the marine in front of it to walk off and run and keep to the left. Stay behind the wall and once he passes back towards the truck run by him. Go left and carry on up the alley and keep to the left. There are three marines unloading crates and just behind the truck is a door. That’s where you need to get to. Go past the Crate-Lifter Suit and hide behind the crates. You can jump on top of them if you want to see where they are. Get to the end of the crates and just dash inside the door when they’re not looking. Go left and around the room and you’ll get to a hole in a fence. Go through the fence to complete the level.
Level 2: Surprise
Quick Facts: Date: November 23, 2230
Time: 10:13 PM
Incident: -1 Day, 07.00 hours
Location: Primary Operations Complex (POC) — LV-1201
The Mission Objectives:
1. Return to the hive.
After the cut-scenes, you will see two guys running away. Go after them and kill them. After killing everybody in the vicinity, go through the APC doors at the left from where you first started the level. Once you get inside the other doors opposite will open automatically. Two marines will appear from beyond the door so hurry up and kill them both. Keeping heading straight ahead and kill any marines you see and go around the corner. When you get to the Bar sign, be careful because a couple of marines will be in front of you and behind you. Head out and a Dropship will land on the Landing Bay after you’ve emerged from the corridor. Explore and kill the man fixing the Dropship and kill the other two marines which follow. Look around for a vehicle that’s blocking the way in an entrance. Go towards the vehicle which is smoking and to the right, a door will open.
Kill the man and carry on into the next corridor. Switch to Night vision and you’ll see some Lasers going across the room so use the ceiling to crawl over them. When you come out of the corridor, you’ll see a man fixing an animal storage unit. Nearby is a marine so take him out as well and head out through the door opposite. You’ll enter a room with another man fixing another animal storage unit. After killing him crawl up to the higher floor. Follow the corridor and you will get to a similar room as before. Kill anybody in this room if you like but just go up to the ceiling and look for a vent. You may need to switch visions if you can’t see it but go through it to start the next part of the level. You will start in the ceiling above two people talking. Change to Night vision and look in the walls for an opening and go through the tunnel. When you get to the next area, drop down from the ceiling and go up the nearby stairs.
You will start in the ceiling above two people talking. Change to Night vision and look in the walls for an opening and go through the tunnel. When you get to the next area, drop down from the ceiling and go up the nearby stairs. You’ll soon see someone fixing a vent so kill him and go through and follow the vent. You’ll eventually come to an opening and just below are two marines talking. Drop down to the ground and kill them both. Explore and go down the dark corridor until you reach the end. When you get to the end go into the nearby room. Smash the Control Desk in order to release Xenomorphs which are caged. Now head back out into the corridor and go in the door nearby and into the Maintenance Tunnel. You’ll be under the floor and above is a marine so break the grill and kill the marine. Follow the corridor and in the corridor, there are two marines sealing up a vent. Kill them and enter the Section 4 Security room. Go through the room and into the Cargo Bay.
Some marines will appear from behind you and also watch out for the Flamethrower. Kill them and you may notice a Predator standing on the roof. Don’t worry just yet, go to the opposite side of the Cargo Bay and smash the door. Enter the corridor and follow it through to the end killing anybody that gets in your way until you get to a door. Go through the door at the end of the corridor and you’ll be in an area with two trucks and an APC. Other Alien Drones will start attacking the three marines nearby. Help them out and finish off the marines left standing. Underneath the truck is a vent so drop down underneath the truck and smash through the grill and follow the vent. You’ll eventually come to a room with two marines waiting for you. Kill them and just above where one of them was standing is a vent. Go through to complete the level.
Level 3: Escape
Date: November 25, 2230
Time: 05:18 PM
Location: Animal Storage. Primary Operations Complex (POC) — LV-1201
The Mission Objectives
1. Return to the hive.
Walk down the ramp slowly and you’ll see a marine setting up a Sentry Gun. Kill him and two more marines will follow him. Kill them and go through into the small room they came from. Don’t go down the ramp and through into the next room because there are Sentry Guns everywhere. Instead above the door is a vent. Crawl up the wall and go through the vent. Follow through and go through the next vent on the left. You’ll eventually come to a ceiling with two rotating fans. Break the device on the wall nearby to stop the fans from rotating. Drop down from a fan and into the room below. Kill the marines in the room and slowly follow the corridor nearby. You’ll be behind two Sentry Guns and another will be across the room on the other side. Smash the two Sentry Guns nearby and in the right-hand corner is a vent. Smash the grill and go inside.
Follow the tunnel through and you’ll be in a big room with water canals at the bottom. You may also hear a Predator roar but you won’t encounter him just yet. Drop down into the water and turn right just before the small bridge. Go through the vent which is on the wall. Follow the vent through and you’ll see two marines from the vent. Kill the two marines and enter one of the broken fans nearby. Go through the vent that’s behind the fan and you’ll emerge under a floor. Switch to Night vision and crawl through the sealed hole above to emerge into the above room. Go up the nearby ladder and you’ll see a man setting up a Sentry Gun. Kill him and go through the vent that’s right next to him. Go through, turn left and get ready for the next part of the level.
Smash through the grill on the vent and you’ll be in a room with an elevator shaft. Kill the marine and crawl down the shaft to the bottom. Watch out for any moving elevators and kill the marines at the bottom. Go down the ramp towards the door. Ignore the left route and go right and kill the marine waiting there. When you go up the corridor, a couple of marines will appear from behind you so take care of them. Continue through the corridor until you get to a small room with a Scientist and another marine. Break through the windows and you’ll be in the next area. Drop down to the ground and kill the marines that come running. Kill them and go down the door they came out of.
Go down the ramp and your objective now is to kill the Predator. He will immediately start firing Plasma Bolts at you so reach the ground where he is. The Predator will now be forced to use his Combstick. Just keep using your Claws on him until you kill him. He will now Self-Destruct so get the hell out of there. Crawl up the walls as far as you can and there will be a big explosion. He has now made a huge hole in the floor for you to escape in. Go down into the hole and enter the corridor. Take the first left you come to and enter the next corridor. Keep on going and that will be the end of the level.
Level 4: Vengeance
Date: January 06, 2231
Time: 09:50 AM
Incident: +6 Weeks, 16.50 hours
The Mission Objectives
1. Liberate the artificial hive.
You will start this level in a ventilation shaft so crawl upwards and you’ll be underneath the floor of some corridors. Turn right twice and climb up onto the corridor. Go left past a room with a Scientist and you’ll reach some ladders. Go up them onto the next floor. Go down the short corridor and in the left-hand corner of the corridor is a grill. Smash the grill, crawl up and follow it until you emerge out of the ceiling of another corridor. From the ceiling, go around the left and get through the grill in the right-hand corner. There are two ways to go from here. So for the walkthrough we’ll go into the room below. Inside a room, a door will be open to the left. Go into it and through the acid-burnt hole and follow the vents around. You come out in an elevator shaft with a Scientist on a bridge below. Go in the door which the Scientist came out of and you’ll see some ladders leading upwards. If you take the door left of the ladders, you’ll find a captive Predalien but there’s nothing to do here so go up the previous set of ladders.
Enter the room up there and you’ll find a Control Panel and you will also see the Predalien from before. Smash the Control Panel and this will let the Predalien loose. From inside the room go into the vent in the ceiling. You’ll emerge in the dark corridor which I told you about before. You will hear the Predalien smash through a door just outside of the corridor. Now go out of the corridor and go through the door which the Predalien has broken. Take the first left into a room containing two sets of staircases. Go up the right one and if the is closed, smash through the window to gain entry. Look for a vent in the ceiling and go through it. Go left in the vent and you’ll eventually get to an open door. Go through it to start the next part of your mission. You begin in front of a doorway where a Scientist is busy typing away nearby. Head left from the doorway, go left and past the table in the middle of the room. You’ll be in another room so just go up the nearby stairs and kill the two marines nearby. Look up towards the ceiling and you’ll see a vent. Go through and enter it.
Follow the vent through and you will eventually drop down with yet more fans nearby. Crawl straight ahead and crawl up out of the vent. You’ll now be in a room near a caged Predator. Go down the corridor and crawl up into the vent where the Scientist is standing. Follow the vent and you’ll drop down an airshaft. Smash the grill and drop down into a room with two Scientists. Walk into the next room and you’ll notice three glassed Aliens on your left. Two more Scientists will be unloading something nearby. Head around and climb up to the platform around on the right. Break the Control Panel and you’ll see the crane spill lots of acid on the floor nearby. This will make a big hole so you can drop down into the next room. When you’re at the bottom, you’ll some Aliens outside so smash the Control Panel near the window. After you’ve done that kill the marines which then come running. Head down the corridor and into a small room. Drop down the ladder onto the next section.
As you head out, three Aliens will run past you. Run behind them and destroy the Sentry Guns in front. Walk out the open door and kill the two Scientists chatting at the Control Desk. Destroy the Power Relay Station 1 Control Panel and make your way back out. Enter the door which is now open and there will be another two Scientists in the next room. Look under the door and you’ll notice a Floor Panel. Break through it and drop down. Follow through and you’ll emerge in the main elevator shaft. Crawl up to the top of the shaft and another Alien will cause one of the fans to break giving you access through. Climb through the broken fan and you will have finished the level.
Level 5: Abduction
Date: January 06, 2231
Time: 11:35 PM
Incident: +6 Weeks, 18.25 hours
Location: Hive. LV-1201. 6 KM northeast of the Forward Pods
The Mission Objectives:
1. The humans are trying to blow up the hive to cut the empress off from her minions. Eliminate the bombs and the humans that placed them.
2. Beware the combat synthetics. They emit no pheromones.
One thing you’ll find out about the level is that it’s the shortest level in the Alien Missions. It’s also quite easy, as you’ve got other Aliens helping you. When you start the level, you’ll start just outside of the Alien Hive. Explore around but be careful of the dangerous plants that grow in the green fog. Go into the Hive entrance and follow the tunnel down. Head out onto the wider path and you’ll see a group of Aliens running towards some people. Follow your Alien friends and kill the marines. Destroy the Sentry Guns and also destroy the bomb they were setting up. After you’ve done this continue up the path. As you go up, some more Aliens will come out of a tunnel. At the end of the path you’re near the bridge is another bomb. For a sneaky approach you can go through the tunnel the Aliens came out of. Just keep heading straight ahead if you want to go at them head on. When you’ve got to the bridge, kill the marines and destroy the bomb. Keep walking up the dark path and you’ll get to some more people.
Kill all the marines and destroy the final bomb. Now you need to crawl down into the tunnel below. It will be all smoking so jeep on crawling and go through the narrow tunnel at the end. You’ll get to an enclosed room with some dormant Aliens. Crawl up to the tunnel in the ceiling or the one in the wall and you’ll finally emerge in the final area. This was the Queen’s breeding area and you’ll notice two marines standing in the large room. Kill them and follow out of the tunnel. You’ll eventually see some more marines up ahead. Luckily your Alien friends will help you out. If there are any marines left just kill them. Follow the bridge and you’ll get to a tunnel. Go through that to complete the level.
Level 6: Pursuit
Date: January 07, 2231
Time: 01:50 AM
Incident: +6 Weeks, 20.50 hours
Location: Near Hive. Access tunnel and neighbouring archaeological dig — LV-1201
The Mission Objectives:
1. Prevent humans from escaping with the empress.
When you start the mission, walk down the left-hand wall. Watch out for the Sentry Guns and kill the nearby marines. Climb down below the Sentry Guns and go left. You’ll soon get to a marine so kill him and smash the grill in the floor nearby. Go down the vent to the floor below and kill the marines down there. Find the Control Panel near the door and destroy it. Once you’ve done this, go through to the next room. Kill the marines waiting for you when you go through and drop down to the floor below where the APC is. Kill the two marines near the door and destroy the Control Panel nearby. Head through the door and turn left. Kill the marines in this room and look up to the ceiling for a vent. You will see two grills with a red glowing light behind them. Crawl up there, smash the left-hand grill and enter it. Follow the vent and smash through another grill at the end to go into the next area. By exploring you’ll find a tall shaft with a spinning fan at the top. Destroy the three Control Panels on the wall at the bottom of the shaft and this will stop the fan from spinning.
Crawl to the top and go through the fan to the next floor. Kill the two marines when you emerge. There are a lot of people in the next corridor. Instead of going through all this, turn left and go through the vent which is on the floor. Follow through the vent to the next room. Climb up the wall and you’ll see a couple of marines. Try and get onto the walkway where one of the marines is standing. Follow the walk way and you’ll find a System Charge switch. Destroy that and an explosion will occur just right of the System Charge switch. Enter the passage and follow the corridor. Head left and you’ll see someone fixing a lamp. To the right of him, there are two more marines standing in front of a door. Kill them all, climb up to the level above and search for a Control Panel. Destroy that and go through the nearby door.
Go left and go through the next door you come to. Kill the two marines and follow the corridor until you come to a large circular room. There are a couple of marines and a Combat Synthetic in this room so be careful and kill them all. Walk into the corridor which the previous two marines came out of to complete the level.
Level 7: Freedom
Date: January 07, 2231
Time: 02:55 AM
Incident: +6 Weeks, 21.50 hours
Mission Time: 0.25 hours
Location: Tunnels leading to the Auxiliary Landing Pad. LV-1201. 2 KM northeast of the Forward Observation Pods.
The Mission Objectives:
1. Prevent the humans from escaping with the empress.
2. Locate primary operations complex.
3. Don’t kill other marines.
4. Locate security station and activate automatic defences.
5. Locate Sergeant Hall.
When you start this level, a lone marine will appear ahead of you. Kill him and look up to the walls. Crawl up the elevator shaft that’s nearby. When you reach the top, kill the two marines on the platform. Enter the corridor and go through the vent that’s in the ceiling. Follow the vent and you’ll see two marines below you. Drop down by smashing the grill and kill the marines. Search for the Sentry Gun Panel and destroy it. Follow the corridor around and enter the room to the right of you. Drop down onto a small platform in the middle of the room and go through the opening. Kill the Combat Synthetic and destroy the Control Switch for the vehicle doors. Go back out of the room and be careful of the marines who are waiting for you outside. Kill them and go through the short corridor which is nearby. You’ll soon come to another Sentry Gun Panel.
Destroy the Panel and drop down to the floor below. Go through into the next room and there are two people inside. Head straight across and turn left. You’ll soon see two marines shooting at a Predator. Kill any marines left standing and climb up to the level above. Turn right, kill the next few marines and follow the corridor to the next room. Kill the two marines standing to the right and follow the corridor until you find an opening in the wall. Enter the passage and you’ll come to a large room. Just above on a beam is a Predator who will blow up an APC. The Predator will leap across to the platform opposite where he will fire at you. Pounce to the platform where he is and just keep using your claws to kill him. After you’ve kill him, find a pipe where steam is coming out of it. It’s on the wall near the Predator. Once you’ve found it, go through it and follow it to the end.
You will see a room which contains water and there’s a marine standing by the pool of water. Jump out of the vent and kill him. Continue through the corridor and break through the fence on the left. Go through that and you’ll be in a huge elevator shaft. Crawl up that slowly and on the first level are two marines. Kill them and look up to find a vent. Smash through the grill and crawl up there. When you get to the top, destroy the Sentry Guns and you’ll see another vent across the room on the other side. Go through that. This will take you to the top of the elevator. Explore and go into the wide corridor opposite. Use your night vision to find a vent in the floor and go through it to the next part of the mission. You’ll start behind a grill and just in front is some people. Smash the grill down and kill the people in the room. Now head left down the corridor. You need to work your way all around the corridor to the end. Kill any enemies along the way.
You’ll eventually reach a Control Panel on the wall near the last door. Smash the Control Panel, head back and go in the door on the left which is now open. This room contains the Landing Hydraulics 1 Control Panel. Destroy that and go back out the door you came in from. Turn right and go through the door and then turn right again to go through another door. When you’re inside, find the Landing Hydraulics 2 Control Panel and destroy that. Come back out of the room and you can go right to start from the beginning or go back left. It doesn’t matter which way because they both lead to the same door. You’ll know the door when you come to it because two Combat Synthetics are guarding it. Kill the guards and enter through the door. Find the vent in the wall and smash the grill to gain access. Follow the vent to the floor above.
You’ll emerge in a room over-looking the Landing Bay. If you go to the window, you’ll see a Predator firing at two marines. Destroy the Control Panels under the yellow sign and head back down the vent. Kill anybody waiting for you when you emerge from the vent. You’ll see a ramp nearby so go up that. When you come out of the ramp you’ll be under the Landing Bay. On the platform above, there are two Predators waiting for you and nearby on a truck in the Queen Alien. Crawl up the walls on the left to get up to the platform. From the wall, you’ll have a good view of where the Predator positions are. One is on a beam opposite and the other is standing on the Landing Bay. You need to get close to the Light Predator so he doesn’t use his Shoulder Cannon. Jump down onto the Landing Bay and kill him. He’s fairly simple to defeat so just use your claws to kill him. Once he’s dead, the Heavy Predator on the beam will leap down to fight you. Use the same tactics as you did for the Light Predator. Keep strafing and clawing him to death.
Once you’ve killed the Heavy Predator, head towards the Control Tower near the Queen Alien. A marine will appear so kill him and enter through the door into a room. Search for the vent, go in there and follow the vent to the floor above. Kill the two marines in the next room and destroy the Landing Beacon. By destroying this, the Dropship is unable to land so Dr. Eisenberg can’t escape. Go back down the vent and onto the Landing Bay. Dr. Eisenberg will run towards you and try to shoot you down so just pounce on him to kill him easily. Once you’ve killed him, you can watch the final cut-scenes where you’ll find out that Dr. Eisenberg is a Synthetic. Well done. You’ve completed the Alien Missions.
