Maps created in Far Cry 4’s map editor do not feature support for competitive multiplayer. The custom map editor only includes options for the game’s challenge maps, and not the competitive multiplayer. This is what Ubisoft Montreal’s Creative Director Alex Hutchinson had to on the matter:
“I direct the game but I don’t set budgets or timelines. We always squeeze in as much as we can, but we’re always prioritizing. We’re going to keep supporting the game, so hopefully we can get it done post release. No promises, but we will try.”
