You get guns. You shoot Guns. Kill Aliens. Everyone Dies.
Graphics:Look fine but FPS lag shows that code could have been written better.
Audio: Many noises ranging from bubbling test tubes to screaming crazy aliens.
Missions: Many random Objectives. You usually just go push a button because you are told to do so, kill lots of baddies, get ammo/health, continue.
Features: Can turn into mutant later in the game, Feels cinematic with unrealistic dual wielding (Rifles/SMGs, Shotgun Dualies) scanning top "secret" documents for bonus material
Weapons: Mostly run of the mill, Shottie, SMG, Sniper but has a cool Alien weapon with bouncing ammo that you can redirect around walls to vaporize your foes.
The Good: Fun, Cinematic Shooting gameplay, Sci-Fi Feel
The Bad: A.I. don't really put up a fight
The Ugly: The Alien bosses, FPS plunges
Replay Ability: Short/Mild
The Bottom Line: A cool Sci-Fi shooter that doesn't go above other games but is fun if you like this kind of stuff plus it's cheap.
