I died probably 20 times or more just to things like this. Or I'd clear a room, go to the next room, and then get killed from behind by a robot that is suddenly just there for no reason. There were times where I'd get shot in the back and turn around and there'd be nothing there or I'd be walking and all of a sudden die to a grenade that it didn't show was there. The enemy AI just seem to hit you no matter what and will appear all around you even if you think you cleared the building or room. And it's interesting at first but gets overshadowed by everything else being so bad.
The game starts off exciting as it shows you all of these new technologies and innovations for you to use.
