The Kingdom is under siege, and only your team of makeshift builders can reclaim it! However, the task is easier said than done as waves of enemies will be set to ruin your efforts. Gather resource blocks, strategically construct barricades to disrupt enemy paths, and craft defensive mechanisms to fortify your base. Battle alongside your custom-built defenses! Use blocks, toss enemies, and even launch your friends to fend off the onslaught in fast-paced, physics-based combat. Stack resource blocks and defenses to amplify their power. Higher stacks mean tougher barricades and stronger turrets—it's all about strategic placement and maximizing your fortifications. Levels have strategic objectives: defend key spots to achieve the highest scores. Experiment with creative setups to complete construction plans and outsmart your foes. Physics-Based Chaos: Engage in mayhem where strategy meets frantic action. Interactive Combat: Grab your teammates, hack enemies, and turn anything into a weapon. Character Customization: Make your character stand out! Local & Online Play: Team up with friends both online and on the couch. Can you outbuild and outfight the invading hordes? Your creativity is the Kingdom's best defense!
