The only gripe I have with this game is the fact it's a spit in the face of the original Doom 3. The load times are extremely long for a game ported from the year 2004, but it also has Doom 2's Wolfenstein aspects censored removing the SS soldiers and Wolfenstein music.
As a fan of the originals this port is complete garbage and just lazy optimization. Play it on Xbox/PC/or download from PS Store, because the disc version of this game for PS3 is terribly optimized and a waste of time.
If you r a fan of the original games, then you r n luck. Both DOOM 1 and DOOM 2 r on this disc! The DOOM 3 game is also very entertaining. It kept me shooting and smiling all weekend. Definitely worth a rent.
