Hero[]
Summary[]
The Hero game mode plays like a regular Team Deathmatch with the exception that each team that has a hero who spawns with all troop weapons and a glowing blue or red aura (depending on team). The hero does extra damage and has extra health. Points are scored for killing enemies. A new hero is selected each time the hero "countdown timer" runs-out or the hero is killed. The new hero is then selected at random.

Collection[]

Collection is a new game mode in which two teams battle it out to capture cores, a bit like a multiple-flag version of Capture the Flag. Points are earned by capturing the cores and bringing them to your home reactor. The location of core spawn zones are always set places.
