This isn't the first Bomberman game to have a Darker and Edgier feel to it. Atomic Bomberman had the titular character with a new design that more closely resembled a robot. Also, the visuals were done with pre-rendered 3D graphics in a similar vein to Donkey Kong Country. But that game also kept the same sharp game-play as the originals and primarily used its new visual style to have a different flavor, and didn't take itself very seriously at all. Furthermore, while Bomberman had a new design, he was still recognizable as Bomberman.
The plot shares similarities to that of the original Bomberman, where the protagonist's main goal was to escape the bomb factory to become fully human. However, the tone of this installment makes it virtually unidentifiable with that game (or the rest of the series).
The First-Person Bomber mode might have been inspired by the gameplay of the Japan-only title 3-D Bomberman, which was actually played in first-person view, unlike Act Zero's behind-the-player perspective.
Too Bleak, Stopped Caring: A Darker and Edgier makeover akin to Halo on a cutesy mascot, along with a lot of bad gameplay choices (no local multiplayer, and a single player mode consisting of 99 levels with no lives, no continues, and no saving) ensured no one would be interested in playing.
