Crustacean Crusaders is a two-player strategy board game that pits two warring factions of crabs against each other for control of the beach. The players use their crab armies to collect crucial resources in the form of seashells and crush their enemies all while avoiding the tide that moves steadily along the board each turn. The tide, while deadly to crabs, refreshes tapped resources as it recedes across the game's grid.

To win, the opposing player's sandcastle must be toppled either by using their crabs to push past the enemy defenses, spending shells to launch bombardments from afar, or getting lucky with special bonus cards that are purchased with shells.

The game boards, bonus cards, and crab soldier are gouache painted. The stacking castle pieces are digitally modeled and 3D printed.
