Fans of the Fallout series have been asking for an MMO or online game for years, and there was much disappointment online when the legal dispute between Bethesda and Interplay ended with the development of Fallout Online shutting down. Now it looks like fans may succeed where the development studios themselves have failed, as modders have managed to add online co-op functionality to the 2010 game Fallout: New Vegas. Titled New Vegas: Multiplayer, the project uses the game’s original Gamebryo engine but has modified it extensively to add multiplayer, with 91,041 additional lines of C++ code.
In order to incorporate multiplayer, the developers had to modify features that usually pause time such as the pipboy menu and the VATS system that lets players target individual body parts. The VATS system was removed in its entirety, while opening the pipboy menu now makes the player invulnerable but doesn’t pause the game. The mod can already synchronise game persistence between each player’s version of the game world, so if someone kills an NPC, then everyone’s mission involving that NPC will fail too. The developer is currently accepting signups for people to test the mod and is looking for more network programmers and reverse engineering specialists. Check out the videos below to see the mod in action.
