Some maps featured in the Big Team Battle: Sentry Defense game mode include Fragmentation, Highpower, Deadlock, Oasis, Scarr, and Command. These maps offer various strategic options for players to defend their Sentries and defeat the enemy team's Sentries.
The main objective in Big Team Battle: Sentry Defense is to defend your team's two giant Sentry turrets while attempting to destroy the enemy team's Sentries. Each team starts with 2,000 points, and as damage is dealt to your turrets, your available score drops. If a team's score reaches 0, the game is over. Players can strategize by either focusing on dealing damage to the enemy Sentries or dividing their forces to both attack and defend.
