Weapon Survivor is a free online arcade shooter where you fight off relentless waves of enemies by shooting and merging weapons to build devastating firepower. You play as a lone survivor trapped on a battlefield, and your only path through is to keep pulling the trigger and upgrading your arsenal before the enemies overwhelm you.

The core hook is the weapon merging system. Combine guns to unlock more powerful versions that tear through enemy crowds faster and with wider spread. As enemy waves ramp up in difficulty, smart merging decisions matter as much as your aim. Position yourself to maximize your bulletstorm coverage, avoid getting cornered, and prioritize merging when you have a brief window of breathing room. The fast-paced, chaotic gunfights keep each run feeling different and push you to beat your previous survival record.

If you enjoy auto-shooter survival games, bullet-hell arcade action, or merge mechanics combined with combat, Weapon Survivor hits all those notes in one compact, browser-based package. It's a great pick for fans of survival shooter games online, free merge weapon games, and arcade-style roguelite shooters. No download, no sign-up - just jump straight into the action and see how long you can last against the onslaught.
