Does Back 4 Blood let you blow a giant bubble around a zombie and then pop it to defeat it? I doubt it. Bubble Bobble 4 Friends would seem, therefore, to be the superior game.
Taito's 2019 revival of the classic arcade series is now making the leap to PC. It's been retitled Bubble Bobble 4 Friends: The Baron's Workshop and includes a level editor, and it'll launch on Steam sometime this summer.
