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). The PDA is included but its functionality is changed: instead of containing crucial information from several key characters, it instead contains a list of credits. In one of the additional mods the PDA also serves as a satellite video uplink showing certain videos from Doom 3 (such as Sarge's messages to the marine).
