Team Annihilation is a game mode where two teams (named Moon and Sun, each with four Tenno) face off against each other. The team must battle each other and defeat them in a confrontation in order to retrieve their Oro, eliminating it. To complicate matters, a Tenno can also reclaim their team's lost Oro if the orbs remain unclaimed by their opponent. The match is decided by the numbers of successful elimination, with the first team to reach 50 eliminations declared the winner.
Tenno combatants can be killed to scavenge their energy orbs if they had some stored. In addition, energy stations are scattered across the level to spawn small energy orbs at preset locations around the map occasionally. If Energy Surge has been initiated, energy stations will spawn medium energy orbs instead.
Energy Surge of the Team Annihilation mode will be initiated if the match has gone over 10 minutes without conclusions. Once initiated, all energy stations will then spawn medium energy orbs instead to further instigate the gameplay, all empty energy stations will also be resupplied with energy orbs.
At present there are four maps available, each possessing their own health stations, energy stations and universal ammunition drops scattered around the map. Unlike regular gameplay, maps are completely fixed rather than randomly generated.
