Missions can be played alone or with up to four players in a player versus environment cooperative manner. Each mission is given a ranking that indicates how difficult the mission is. Missions are generally played on randomly generated maps composed of "tiles" of map sections. Missions have various objectives, such as defeating a certain number of enemies, collecting data from terminals without activating alarms, rescuing prisoners, or defending points on the map for set periods of time. Newer updates have added space-bound combat using Archwings, and a large open-field environment where numerous bounties can be completed. Players can use their weapons, special abilities, and a number of parkour style moves to navigate through and overpower forces within these missions. Downed players may be revived a limited number of times on any map. Once complete, players are rewarded with in-game items, as well as in-game currency and items picked up while exploring the map; failure to complete a mission causes these rewards to be lost. In addition to cooperative missions, the game includes player versus player (PvP) content through the multiplayer "Conclave", which also rewards the player for placing high in such matches.
