SoulTrigger

SoulTrigger is a two-character, turn-based tactical roguelite RPG set in an urban fantasy world. As the Commander, you lead a squad of Souls (S.O.U.L.) into a sealed Hazard Zone to hunt down Milo, who escaped with the core device of Halcyon’s Soul Materialization Project. The project extracts human souls and etches them into synthetic bodies; its failed experiments became feral Creatures. Your squad members are weapons stripped of their memories and flesh, and they can be printed anew if their bodies are destroyed. As you explore, you collect memory fragments that reveal more about who your soldiers once were, leading to a choice with no turning back.

Explore the Hazard Zone

Each run follows a single route through connected rooms. At forks, you choose where to go next, facing battles, elite fights, events and shops before reaching the boss. Keys earned in battle open locked rooms and chests, while 40+ events ask you to weigh costs against rewards. You also encounter other Souls who stand in your way.

Fight with two operators

Choose two of four operators: Harang, Siwoo, Valentin and Loke. Combat takes place on a side-view tile grid. Action Points refill each turn and let you move, turn, use items and fire skills instantly in the direction you face. You control one operator at a time and can switch to their partner to continue a combo.

Enemies telegraph heavy attacks one turn ahead, giving you a chance to avoid the danger zone or interrupt them first. Fill an enemy’s weakness gauge to trigger a Weakness Burst, which can knock it down or freeze it and cancel its prepared attack. Battles have multiple waves, and Elite monsters with special abilities also stand in your way.

Each operator has a distinct passive and fighting style:

• Harang: drives a Nail bullet into enemies with every attack, then detonates them all at once.
• Siwoo: uses deployables such as turrets and drones, and charges a Taser to call down lightning.
• Valentin: marks weak spots to boost damage and critical hits for the whole squad.
• Loke: builds Rage and tears through the enemy line in Soul Overdrive.

Build each run

Traits found during exploration combine with 30+ Relics that last for the entire run, letting you create a different build each time. Operator-exclusive traits sit alongside shared traits that trigger with melee, ranged, throwing and deployable skills, creating different synergies.

Strengthen your squad

Expeditions bring back Grit and Growth Factor, which you use to strengthen your operators at the base. Raise ATK and HP at the Training Center, and unlock operators, skills and traits at the Control Terminal before returning to the Hazard Zone.
