Space Invaders on the GBA is basically the classic arcade shooter you already know, but now it fits in your pocket. You're still lining up shots under that creepy descending alien swarm, trying to pick them off before they reach the bottom. The sound effects are just as satisfyingly retro—that pulsing soundtrack speeds up as the aliens get closer, which still makes me panic a little.

It's simple, sure, but there's something weirdly addictive about clearing wave after wave. The GBA version keeps it faithful—no fancy upgrades, just pure "defend Earth from pixelated doom" vibes. If you've never played it before, you'll understand why this thing started an arcade revolution back in the day.
