Outside BlacShark's recent projects like Space Shark Alpha and PvP Pong, ever wondered what else is cooking? This intrepid developer is apparently working on a new Doom port, and as part of testing on the game engine, BlackShark has developed a set of maps titled Perfect Hatred. Here's a screenshot to demonstrate what to expect:

While the Doom port's still a TBA deal, the maps should work nicely with Stereomike's DoomPSP .5 (and above) homebrew game. More details on these custom maps are available at the forums, which should be your next stop after downloading this WAD file. Enjoy!
