Not to be confused with Released.
Release takes place in a Flood-dominated environment, featuring wreckage and numerous Food structures. Notably, there is a crashed DSC-class support ship in the southwest corner of the map. The map has two control panels that players can garrison infantry units in and activated to unleash Flood units on the enemy for 600 resources. Both Flood spawn points are located near the starting base locations, but the released Flood units could attack both players.
