Plan 8 From Upper Mars is one of those classic Flash games where you hop into Daffy Duck’s ridiculous spaceship and blast away at Martian invaders. It’s got that old-school cartoon vibe—bright colors, goofy sound effects, and enemies that look like they escaped from a 1950s sci-fi flick.

You start off with a basic blaster, but after a few waves, you’ll snag upgrades like spread shots or homing missiles. The controls are simple—just arrow keys and spacebar—but dodging all those alien fireballs gets chaotic fast. And yeah, Daffy’s one-liners never get old, even if they loop a little too often.

It’s short, silly, and exactly what you’d expect from a Duck Dodgers spin-off. Perfect for killing 10 minutes between real life stuff.
