Play Chex Quest 3 Online

Chex Quest 3 is the kind of game that makes you stop and ask, "Wait, this was a cereal box promo?" It’s a full-on, no-joke FPS where you blast neon-green alien goop monsters with a sci-fi zapper—like if Doom got remade by someone who really loved breakfast. The third game in the series (yes, there were three) throws in new weapons, chaotic levels, and even multiplayer, so you can team up and splatter your friends in slime.

The whole thing feels like a weird, wonderful accident—somehow, a marketing gimmick turned into a legit cult classic. The fan-made third installment polishes up the retro graphics but keeps that fast, frantic '90s FPS energy. It’s nostalgic, ridiculous, and honestly way more fun than it has any right to be. If you’ve ever wanted to save the galaxy before homeroom, this is your chance. Just don’t expect a spoon in the box this time.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
