About game
Strategy fans wanting a high-octane challenge will find their new obsession in Crab Swarm Defense. Endless waves of crustacean invaders march toward your core, forcing you to think fast and build smart. You start by placing turrets along the path to thin the herd before they reach your base. Scrap management remains vital because every gun placement impacts your budget for future upgrades. Active abilities like lightning storms or repair pulses help you survive when the swarm gets overwhelming. Collecting blueprints in the hangar allows you to unlock new weaponry for subsequent rounds. Upgrading your base stats with void shards creates a satisfying progression loop that keeps you coming back for just one more attempt. Competing for a spot on the global leaderboard adds a layer of intensity to every session. Jump into Crab Swarm Defense in your browser right now with no download required.
