So far from the two hours I could play:
Where is my pulse rifle? This is some new version with less ammo than the normal one? Its uglier and no grenade launcher? This pulse rifle is a let down to me.
The alien warrior is too brown, should be more black and blue, to me it looked brown like the resurrection drones did, will have to recheck when I get home and more time to study it.
AI are useless, can forget about beating this game on harder difficulties alone.
The marines facial look and customs one can do is way too little and limited, not many haircuts one can chose from or edit ones charachter and armour and stuff besides weapons are very limited. Preodrering this game in that sense was a waste of money, dlc might make it worth the money later.
Charachters dont move their mouths when they talk, very stiff models.
Like acm the holes and ducts the aliens use isnt even textured and just a hole on the wall, dont lead anywhere. Same issue as acm.
Else on the plus side besides others said: its fun and the alien models move amazingly well but the game is shallow and I dont see reasons why to keep replay it to earn money, money for what exactly? There isnt anything i teresting to buy for the charachter :/ but its a solid horde shooter, could kill xenos easily with the pistol, shall see if I can do it easily with meelee too when im home.
