In a recent AMA thread on Reddit with the Far Cry dev team, Game Director for Far Cry 6 Alexandre Letendre revealed that Far Cry 6 won't be seeing a return of the Arcade Mode. Taking over as Far Cry 5's incarnation of the Map Editor, a series staple from as far back as Far Cry 2, this was a popular feature allowing players to create their own maps. The Arcade Mode in Far Cry 5 even beefed it up by integrating the use of fanmade stages into the game's main multiplayer mode.
The response from the dev team said removing the map editor was "a difficult decision, but allowed us to focus our efforts on the main campaign, transporting players into the heart of a modern-day guerrilla revolution." While the multiplayer angle of Arcade Mode may be getting the chop, the full game will be playable in co-op, with the tether system seen in Far Cry 5 and New Dawn in use once again.
Far Cry 6 is due to release on October 7th for PS4, PS5, Xbox Series X, Xbox One and PC.
Food For Thought:
Adding extra detail to the main map itself is an understandable priority and is likely to make a noticeable difference on the final game.
With that said, the popularity of Arcade Mode and the dev team's clear disappointment at having to remove it means it wouldn't come as a surprise if the team may try and add something resembling it back in later, even if the map editor side of things takes a backseat to the multiplayer deathmatches. Time will tell.
