Undermoon

Undermoon is a single-player, turn-based tactical roguelike RPG set in a dark fantasy world. You plan moves on a square grid, combining weapons, skills, elements and terrain to win battles. After waking in an unfamiliar town, you gather equipment and supplies, travel through mysterious portals and investigate a world that no one knows how to leave.

The town and portals

The town is home to castaways from different races, eras and worlds. No one knows who brought them there or how to escape. Beyond it, portals lead to distinct themed areas spanning multiple floors, with handcrafted spaces and procedural layouts that offer different routes, traps, enemies and bosses.

You can return to town after completing an area's challenge to talk, trade and adjust your equipment before choosing another portal. Darkness, visibility and traps test your judgment, while hunger, food and medicine test your preparation. Death ends your current run, and you carry what you have learned about enemies, the environment and your build into another attempt to find a way out.

Tactical battles

Movement, attacks and skills resolve through turns. You assess enemy positions and attack ranges, hold narrow passages, knock enemies back to make space and move away before a boss strikes. Boss attack telegraphs help you judge when to act, while enemies and bosses bring distinct abilities and battlefield mechanics that call for changes in position and skill order.

Elements and terrain

You can set the ground ablaze, spread lightning through water or push enemies onto hazardous terrain. Water, ice, fire, lightning, acid and steam create opportunities to combine weapons and skills, but the same hazards can threaten you. Leave room for your next move when using the environment.

Shape your build

Choose a race, distribute attributes and develop your character through skill trees. Your options include melee weapons, bows, firearms, elemental magic, psionics, summons and defensive abilities, alongside equipment and consumables. Combine abilities to control enemies, create space for ranged attacks or bring summons into a fight. Bosses in some areas grant a powerful Tower Gift, which opens new directions for your build during the current run.
