There are different types of bonus features to be accessed in this game. There are 3 different levels for you to experience. It is rare that in an online slot, there are levels of bonuses, it is a great idea from Netent as it gives players something to work towards and keeps them interested. On the first level, you have to search through the infected area in a hunt for the Aliens. All of the symbols apart from the wild symbols will be added to the Activity Meter and will increase the value of the multiplier by 1. If the meter reaches its highest point, you can then move up to level 2.

On level 2, your mission is to reach the Queen hive. If you run out of ammo, you will be removed from the level. Each new spin from here will activate a bet line win with 3 added symbols. The ammo symbol will appear in the centre reel and it will increase the ammo clip counter. This will then activate some re-spins for you.

On the third and final level, you will reach the hive, where your aim is to kill the Queen before the Alien does. The Hive health meter will show you how much life is left in the Hive. The ammo clip counter contains 4 ammo clips, which will give you 5 re-spins. During this level, multipliers can appear randomly on the reels with values between 1x or 10x your betting stake.

It is not often that you will find a slot game of any kind of theme that will go into as much depth with their bonuses like this one and actually make their slot game more of an actual game instead of just a slot that you spin to win money.

Alien Robots

Alien Robots has a more subtle approach to the fierce alien slot. The one we discussed earlier is a more movie themed Alien slot game where the Aliens are deadly, and you are sent out on a mission to destroy them. Where as this online slot game has a calmer and more child-like graphics to it.

Alien Robots is a 5-reel slot game with a total of 243 pay lines. This is another online slot game that is powered by Netent.

There are 2 different bonus features that are included in the Alien Robots slot game. The first one that we will look at is the free spins bonus feature.

Whilst in the free spin’s bonus game, the wild symbols become more valuable.

You will then get a free re spin whilst the sticky wild remains in place and this will give you a better chance of landing a winning combination.

The other bonus feature that is available is the 243 ways to win bonus. The Alien Robots allow you to pick the number of pay lines that you want to bet on.
