It was a long shot hope by fans, but DICE general manager Karl-Magnus Troedsson has officially confirmed that Battlefield 4 will not support mods in any shape or form.
The developer never sanctioned the use of mods in Battlefield 3 as it feared that it would lead to exploits in multiplayer and it appears that it is taking the same stance with Battlefield 4.
“We get that question a lot”, he told PC Gamer. “I always answer the same thing, and then the community calls me bad names. We get the feedback, we understand it. We also would like to see more player-created content, but we would never do something like this if we feel we couldn’t do this 100 percent. That means we need to have the right tools available, we need to have the right security around this regarding what parts of the engine we let loose, so to say. So for BF4 we don’t have any planned mod support, I have to be blunt about saying that. We don’t.”
