Ordinary 3d shooter. Nothing more. Levels are bit ripetitive, especially those in the city. Sometimes there are missions that try to introduce a little diversity to the same routine of "shoot, shoot and...shoot", but they are nothing special. The game delivers what promises though, a mecha shooter in a cyberpunk setting, I think influenced by Blade Runner.
One thing I really don't get is: why, in a shooter, is there such a shortage of ammo? In many firefights I was involved in I was forced to backup in search for ammo. I think this mechanic doesn't play favourably for the game.
