Mr Autofire is a fast-paced free online shooting game where you play as the last line of defense against non-stop waves of alien invaders pouring through tears in reality. Armed with an auto-firing weapon, you run, jump, and shoot your way through increasingly chaotic levels while racking up the highest score possible. The controls are tight and the action never lets up — one moment of distraction and the aliens will swarm you.

What keeps players coming back is the progression system. Between runs you unlock new worlds, discover more powerful weapons, and stack perks that make your character faster, tougher, and deadlier. Some perks improve your dodge ability, others boost your fire rate or damage output. Finding the right combination for your playstyle is half the fun. The retro pixel art style pairs perfectly with the hypercasual pace — easy to pick up, tough to master, impossible to put down when there's a personal best on the line.

If you enjoy endless arcade shooters, run-and-gun games, or hypercasual shoot 'em ups with upgrade systems, Mr Autofire delivers exactly that. It's a great fit for fans of classic alien shooter games, side-scrolling action games, and anyone hunting a free browser game with real replayability. No download, no sign-up — just jump straight into the chaos and see how long you survive.
