Space and alien games either send you outward or bring invaders in. Star Wing is the one with a full write-up: you pilot Earth's last hope, dodge alien fire and upgrade the ship between waves of enemies. Across the wider list you'll find pixel-art arena space battles, a social deduction game set on a spaceship, top-down survival against alien swarms, platformers with alien foes, vehicle combat on strange worlds, and lighter oddities like a flying pig or a magic finger that flicks invaders away. Most start quickly and invite another run after a crash. Free in the browser, with nothing to install.
