In this mode, players have respawns available to them, allowing for more aggressive gameplay.
Concord will have 12 unique maps at launch, set on various in-universe worlds. These maps, such as Freewater, Water Hazard, Shock Risk, and Star Chamber, showcase different parts of Concord's sci-fi world and offer diverse combat arenas for players to battle in.
