To make multiplayer more interesting, Doomero has disabled Monster infighting, although in certain cases this can alter gamplay (such as the room in MAP08: Tricks and Traps in Doom 2 containing the Cyberdemon and the Barons, which require triggering monster infighting to succeed). Unlike some other mods, Ultimate Super Doom 3 is much more complex, importing not only the weapons and enemies but also much of their behaviour from Doom 3: for instance, the BFG 9000 can be charged to release a more powerful shot. The mod's primary purpose is to port weapons and enemies from Doom 3, including weapons and enemies which were present in Doom 3 but not in the original games.
