About

ShootUp.io is a chaotic zombie shooter where you battle hordes in a run-down town. Blast undead foes with guns, drive vehicles to crush them, or set traps like turrets and landmines. Play solo or invite friends via a shared link to build defenses and outlast rivals. The goal is simple: survive waves, grab power-ups, and rack up points before getting overrun. This browser-based game leans into fast-paced, no-frills action that’s easy to jump into. Its open-ended approach lets you experiment with weapons and tactics, while leaderboards track your high scores. With over 1 million hours played since 2020, it’s a staple of the .io genre that keeps things brisk and bloody. The lack of complex systems makes it a go-to for quick sessions of mindless mayhem.
