In Headbutt Knights, players dive into a fast-paced and absurd top-down 2D pixel art action game where the only way to defeat endless waves of monsters is by smashing them with powerful headbutts! Play solo or team up with a friend in local co-op mode and battle through arenas infested with grotesque creatures. Explore different environments filled with traps, power-ups, and hidden secrets. Upgrade your skull with ridiculous abilities like flaming horns, seismic explosions, or rocket-powered headbutts, and unleash devastating combos to achieve high scores. Survive as long as possible, dodge enemy attacks, and take on colossal bosses. Only the toughest (and hardest-headed!) will come out victorious. Are you ready to smash everything in your path?
