Gambit

Gambit is an upcoming game mode for Destiny 2, set to be introduced in Forsaken.

The mode is a combination of PvE and PvP, featuring two teams of four Guardians each. Players compete to kill enemies, and then kill each other. Each team has an energy bank and compete to fill up that bank with motes of light. When the bank is full, a team will be able to summon a "prime evil" and invade the other team.
