Gatekeeper sends players after the stolen Heart of Time, following its trail toward the Throne Room for a final confrontation with Chaos. The journey also pits them against Chaos’s elite Sirens and the legions at their command. Its action rogue-lite framing puts a dangerous, escalating enemy force at the center of this fantasy adventure.
Players can choose among nine Gatekeepers, each with distinct skills, and develop their potential by gaining experience. The game’s build-making comes from pairing those abilities with artifacts: its more than one hundred power-ups can be combined into Triads, with effects that reshape combat. Across five planets, each location offers one of four mission types; completing a mission summons a Siren for a major battle. These linked objectives, character choices, and artifact combinations give each run several layers of tactical decision-making.
That cooperative option sits alongside a structured campaign of planet-based objectives and boss encounters, while the varied Gatekeepers and artifacts distinguish its combat-focused rogue-lite design.
