This is a awsome shooter!!!
so bloody. you should put LOTS more gore. maybe make a SONIC version. OR MAKE A FOURTH ONE. if you want more ideas like a halo version, (i just told you. LOL) keep in touch man, K.I.T.
the only thing that could possibly be better is thing-thing arena online.
really fun i loved it
you have to press f (execution) as soon as the flinch (when you hit or shoot them) and press f again when you grab the enemy to perform the execution with a pipe (i dont think you can use another weapon for an execution)
this game is EPIC WIN!!
