Yep its real good. Its basically the halo of PS2. Its more bullets and grenades than lasers and plasma grenades. Its more realistic in the aspects of running, climbing ladders and even bullet damage. I highly recommend it if you like console FPS games.
this game looks very good, ive only sampled it and it did remind me a bit of halo. so if you are a ps2 owner looking for a spacey amazingly good FPS game, go with this.
