Doom Eternal, which Bethesda revealed at QuakeCon yesterday, will not support mods at launch, but might support them "down the road", developer id Software has said.

During a Q&A session following the reveal, game director Marty Stratton said there was "no guarantee" that the game would ever support mods, but added that the studio has spent time making the "game code more flexible", and that mod support is a "long-term initiative".
