Fantastic retro FPS experience ala F.E.A.R. mixed with Ion Fury. Gameplay is fast and intense, it can get pretty hardcore cause enemies are programmed to flank you and surround you so it will require full use of reflexes, strategics and quick thinking.

My one gripe would be some of the puzzles which can get pretty tedious and the fact that it's a looooooooong, took me almost 13 hours to beat on my 1st playthrough.

Other than that, excellent example of why indie FPS' are king right now.
