Exhumed/Powerslave Dehacker fixes strafing, which always been ruining Dos version of game. Game is ok, I would not call it hidden gem. It is one of the better looking Build engine games, even if it lacks slopes and all that kind of sh*t. Bright, colourfull, althought brown textures are quality work. I would say it is graphics wise best looking Build engine game, above Duke and Shadow Warrior. But outside of graphics is generic. It is not as fast and minimalistic as Doom, nor interactive like Duke. I still wait if Kex engine version would be console port, those take everything good from this and invents it's own thing.
