On the maps are several Control Points which you are to capture by repairing them. When such a point has been captured your team will gain 1 capture-point per second, each map has its own points requirement for winning the game, the more control points you capture the faster you reach the requirement and win the game.
The map is based around a Single Player Hand of Nod building with a huge interior with elevators and everything. There are a total of nine Control Points on this map.
