Gambit is a unique PvPvE gamemode in Destiny 2. In it 2 teams with 4 Guardians each compete against each other by trying to get as many motes as possible, summoning the Primeval and killing it quicker than other team. Players can also invade other team's zone to try to stop them.
While this gamemode sounds fun, Gambit also has a lot of problems. The main one - a necessity of a reliable team, as random players cannot effectively communicate with each other. Gambit bounties are also difficult, and rank requires hours to be increased. Buy Gambit Boost by Overgear and quickly reach a desired gambit rank, complete bounties and unlock seals and triumphs.
