Swarmhold

About the Game

Swarmhold is a cooperative roguelite base-building game for 1-4 players. Hordes of enemies pour in from every direction. Your job: build walls, specialize towers, draft blueprints, and hold the line.

Build Your Fortress Explore the map, find your foundation, and make it yours. Place walls, build extractors for gold, and specialize towers into distinct roles. Upgrade them to their full potential and turn your base into a bullet heaven — mowing down entire swarms before they ever reach your walls.

Shape Every Run With Blueprints As your run progresses, draft blueprints that evolve how your defenses perform. Curate your blueprint loadout before each run, then draft from it as the chaos escalates. Your choices going in shape what your fortress becomes.

Constant Pressure, Not Waves Enemies don't wait for a timer. They trickle in constantly, and randomized events spike the pressure — directed surges, elite spawns, multi-front pushes. You'll get a warning before things escalate. You won't always be ready.

Unique Builders Each builder brings their own structures, abilities, and blueprint options. You're not just building — you're in the fight, holding the line alongside your defenses.

Co-Op That Matters Coordinate defenses, cover each other when things go sideways, and pull off clutch saves that wouldn't be possible alone. Solo is fully viable on every difficulty. Co-op is where the stories come from.

Explore New Biomes Each biome brings its own events, enemies, and challenges — no two biomes play the same.

Unlock Everything Unlock new builders, biomes, blueprints, achievements, and more between runs. Every unlock gives you new ways to play, not more power.
