Vein: Dungeon Ecosystem

The tunnels you dig become the battlefield. The ecosystem you grow becomes your defense. Vein is an ecosystem-driven roguelike defense game. Excavate an underground dungeon, raise autonomous creatures, and stop invading squads from carrying your Dungeon Core back to the surface. BUILD A LIVING DUNGEON Dig new routes, connect the Core to magic walls, and shape a habitat where creatures feed, move, grow, and fight according to their own behavior. DEFEND THE CORE Read each invading squad's roles and classes, then use terrain, creatures, facilities, and carefully timed interventions to break their route to the Core. EVOLVE EVERY RUN Choose one of three upgrades when your dungeon levels up. Strengthen creatures, expand the magic vein, improve the environment, and create a different strategy each run. EXPLORE A COMPLETE CAMPAIGN Fight through 12 distinct locations, 36 stages, and 108 assaults. Settle your run, carry earned DP forward, summon creature cards, and begin the next dungeon with new possibilities.
