Crab Swarm Defense is a fast-paced tower defense strategy. Hordes of crabs march toward your core in relentless waves — build your defenses and hold the line.
• 20+ unique turrets: machine guns, frost, tesla, sniper, mortar, laser, railgun and more.
• Active abilities: lightning storm, freeze nova, core strike, repair pulse.
• Dozens of crab types: fast, armored, flying, shamans, splitters and mighty bosses.
• Meta-progression between runs: unlock turrets in the Hangar with Blueprints and upgrade your base with Void Shards.
• Endless waves of rising difficulty, achievements and a global leaderboard.
Place your turrets wisely, combine abilities and see how long your base survives!
How to play
Your goal is to stop the crabs from destroying your central core.
1. Build turrets and walls with the bottom-left buttons, spending Scrap. Place them along the crabs' path.
2. Generate Energy (generators) and cast abilities with the bottom-right buttons: area damage, freeze, repair.
3. Click a built turret to upgrade it or sell it back for part of its cost.
4. There's a break between waves — reinforce your defenses before the next assault.
5. After each run, unlock turrets in the Hangar with Blueprints and upgrade base stats with Void Shards in Upgrades.
Controls: mouse to build and cast, WASD/arrows to pan, wheel to zoom.
