Presumably in order to keep a T rating, the game was polished a lot. Blood and gore were removed entirely, including scars on character models. Characters Cadavre and Grrl, whose appearance was basically only consisting of gore, were removed from the game entirely. Satanic imagery (pentagrams, inverted crosses) were also removed, as well as the cigar belonging to the character Sarge.
- On the map Forgotten, one of the walls has a UAC sign from DOOM on it.
- In the training center, there is a hidden room, inside of which you can find a 2D red key-card from DOOM. There is also a drawing of an Imp, one of the enemies in DOOM.
