Project Warlock is a good, solid homage to the classic 2.5d shooters like Doom, Heretic, etc. I really enjoyed the game, I liked the art style & the upgrade systems & weapons. A few detractions being the levels are fairly short & small & they all tend to be rather "horizontal" & flat in design w/ little changes in elevation & very little verticality. The most complex levels in the game tend to be key hunt mazes w/ no puzzles, few stage hazards, no set pieces or anything, just requiring you to collect keys & back track.
