Konami announced today that the latest installment in the long-running Bomberman franchise arrives this September. Super Bomberman R 2, initially revealed last year, marks the series’ 40th anniversary by taking the foundations of its 2017 predecessor and adding level-building and a wacky 15 vs. 1 mode.

For this installment, Konami added Castle mode, featuring “attack vs. defend” gameplay where you try to overtake or protect a fortress. Teams of 15 will try to open all the treasure chests to unlock passages into the castle; the lone keeper tries to keep at least one locked before the game’s end. It looks every bit as chaotic as you’d imagine. In addition, the returning game modes include Standard (classic gameplay), Story mode (a single-player adventure), Battle 64 (battle royale) and Grand Prix (“compete for crystals and knock out other players”).

Meanwhile, the new Stage Editor lets you create and share your Castle mode stages. Following the trend set by franchises like LittleBigPlanet and Mario Maker, Konami envisions a robust community of online creators giving you virtually unlimited content.

Super Bomberman R 2 launches on September 12th (although digital versions arrive a day later) and is available for pre-order now. It will support the Nintendo Switch, PS 5/ 4, Xbox Series X / S, Xbox One and Steam.
