A bunch of new WADs are available for Doom for the PSP, courtesy of michalt441. There are four mods available: Duke Nukem, Quake 4 and Quake 2, and Fistful of Dollars (based on the movie of the same name, starring Clint Eastwood).<br><br>Michalt441 has personally tested all these games and remarks that they work, although some of them crash sometimes. Michalt441 promises to release a compilation of even more WADs for Doom in the future so you can watch out for that one.<br><br>Here are some notes before you get all gung-ho. The Quake 4 mod only has one level available, while the Quake 2 mod replaces 10 entire levels for the game. Ok, there, go gung-ho. Remember, these are known to crash units so be careful when using them.
