Xenon 2 on the Game Boy is one of those shooters that feels way bigger than the tiny screen it's on. You're blasting through waves of alien ships, dodging bullets that come at you from every angle—classic vertical-scrolling chaos. The music's got that grungy synth vibe (even on the handheld version), and the power-ups actually matter—you'll be sweating over whether to grab the spread shot or the homing missiles.

It's tough, no lie. Some of those later levels feel like the game just hates you. But when you finally thread the needle between a wall of lasers and a swarm of enemies? Pure satisfaction. The kind of game you keep coming back to even after you've rage-quit twice.
