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.
