Super Maximum Overkill by SpacePantsGames has been published in May 2022 for the Sega Genesis / Sega Mega Drive.
The player’s autofire shooting tank moves around in an enemy field, shielding and protecting itself. When you pickup the leftovers of your opponents, your OVERKILL bar refills and you get 10x more points during those kills. It’s a challenging shooter, supposed to look hard but much easier to play. Give it a try and see for yourself!
