Roguelike + DOOM/QUAKE. If you like any of those give this one a shot. It has some new mechanics with guns and perks per level, some good and some make the game a wild time. Definitely worth the try at FREE
This game owns. Awesome little game to waste a half hour of time or whatever. The perks and guns feel great (I mean cmon, party gun) and unlike others I enjoy the skulls pushing you forward (although I wish they didn't clip through the floor to get me sometimes).
The hook feels decent, but it doesn't always orient toward the crosshair which got me sticking to the floor at random moments. That and I'd kill to play this in widescreen and/or turn down whatever contrast filter is on all the time.
But otherwise yea, this game owns.
Did I mention it owns?
5* Even I hate those flaming skulls. :)
