Great game.
This game is brilliant. I've never seen anyone put uniqueness, awesomeness and endlessness in one game.
It does get repetetive after you find out the blaringly obvious secret: The clones move only until they reach an armlength of you. After, they just go into an endless walk cycle in place.
What you do is put two piles of bodies. Not one, but TWO. You have to be in between them and rack them high. They'll eventually be too high up for you to get hurt. When that happens, use only grenades and psychokinesis; NEVER LEAVE YOUR SPOT, AS YOU WILL GET SHOT BACK UP. When you get the gun, technically it's as good as killing the clones forever.
@The Players: Happy shooting!
@Mo, Cheppy and Samakor: Great game. It had me hooked for hours.
