This is a first person shooter were you get the chance to both run around on foot and also pilot MCAs (Mobile Combat Armors). The levels were you use the MCA is easy and you don t have to worry much about any of the enemies. The other levels when you are out of your MCA and is more hard as the weapon in the game is a bit on the overkill side and enemy artificial intelligence is not that good. Sometimes you can open a door and die before you even have to time to see what killed you. There is a also story somewere in there but it s mostly confusing and not very well explained so the best bet is to ignore it
