ive been playing the preorder alphas and its a pretty good game, it just gets a little frustrating when you dont know how to do stuff, with no AI difficulty you end up getting your shit stomped 80% of the time. The level editor is greek to me, but i figured out how to drop weapons for myself and even out the odds a little.
If you think you're gonna be buying this game when it releases, just do the Dev's a favor and buy a pre-order. They need money to finish the game. its about $35 and you get to play it immediately
