Xenon 2 on 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 all angles—classic vertical-scrolling chaos. The music's got this weirdly catchy synth vibe, and the power-ups actually matter—like, if you don't grab the right ones early, later levels will wreck you.

It's not the smoothest port (this is the Game Boy we're talking about), but there's something satisfying about how frantic it gets once you're deep in. Just don't expect to beat it in one sitting unless you've got reflexes like a caffeinated squirrel.
