ABOUT THIS GAME Time is collapsing. The Protocol is broken. Wield devastating weapons and survive a relentless onslaught of bullets in Protocol: Bullet Hell , an intense 2D top-down roguelite shooter. Your first challenge: survive the chaotic, gun-slinging badlands of the Old West. But your fight is just beginning. SURVIVE THE ONSLAUGHT Master fast-paced, twin-stick combat. Dodge thousands of projectiles. Defeat endless waves of enemies, elite foes, and screen-filling bosses that will test your skill and reflexes. BUILD YOUR ARSENAL Death is just a setback. Grab powerful weapons like the auto-revolver and the devastating shotgun. Stack game-breaking upgrades—from bullet bounces to electric bolts—and create a new, unstoppable build with every run. A UNIVERSE OF CHAOS The Old West is only the first stop. Your battle will span across time and space. We plan to dynamically expand the game with entirely new eras, each with unique enemies, weapons, and challenges: Feudal Japan: Dodge shurikens and face down mythical warriors. Neon Space Zone: Blast cyborgs and hostile aliens with futuristic tech. ...and more! This is an ever-expanding 2D universe where every update brings a new world to conquer. Your fight is just beginning. Can you survive the protocol?
