Description
About This Game
Build by day. Survive the skeleton siege by night.
YAARRGH! Battle Island! is a co-op pirate base-defense survival roguelite where you gather resources, build fortifications, load cannons, and defend a procedural island against escalating skeleton sieges. Play solo or with friends, strengthen your build, reinforce your base, and survive as each night grows deadlier.
Build by Day. Defend by Night.
Every run is a race against time.
By day, you scavenge the island for resources, expand your fort, and prepare your defenses.
By night, skeleton hordes attack in increasingly dangerous waves.
Survive longer, grow stronger, and hold the line as the siege escalates.
