This is a single-player Roguelike 2D game. Over 3,000 character entities can appear on-screen simultaneously. Players can bring up to 4 automatically controlled characters into the game. Both these companions and the player character are equipped with a "‌Sentinel‌" that moves alongside them, periodically attacking the nearest target. The Sentinel's attack speed increases with level progression.At the start of a stage, both the player's faction and the enemy faction summon minor characters to engage in combat. The number of these minor characters can be expanded through in-game store purchases. During gameplay, the player-controlled character navigates the stage to evade enemy attacks, utilizing the Sentinel and active skills for tactical operations.
