Space Invaders '91 on the Genesis is basically the arcade classic with a slick 16-bit makeover. The aliens look sharper, the explosions pop more, and your ship actually has a proper shield meter now instead of those flimsy destructible barriers. Feels way less cheap when you take a hit—you can actually tank a few shots before blowing up.

Still plays like classic Space Invaders at its core, just with enough tweaks to make it feel fresh. The patterns get wild fast though—some of those later waves have aliens zigzagging in ways that’ll make your thumbs sweat. If you dig the original but want something with a little more punch, this one’s a solid pick.
