With the PS Vita version, a multiplayer mode allows you to play with multiple consoles, but a PS4 is required to host the game.
Sanuk Games Manager Yan Marchal talked about Bombing Busters, which sees you fighting bosses and bombing critters in a series of 30 mazes:
True to old school standards, its difficulty ranges from hard to harder, hardest and then extreme as you progress in the campaign! But fear not: you may easily restart from the latest completed level, and skip bosses if they’re too tough for you to handle!
The game features five picturesque worlds with multiple environmental gimmicks to keep you challenged, and lots of items and power ups to collect.
A North American release date wasn’t announced for Bombing Busters, though it should arrive in a couple months if the PS4 version’s timing is anything to go by.
