In 2004, Bomberman Online got ported over to the PlayStation 2 in Japan only as Net de Bomberman. Unlike the US-only Dreamcast release, it is completely designed around its (now defunct) subscription-based online multiplayer, without any support for offline play. Only playable online, the game features ten different maps, based on the grid-like mazes seen in classic Bomberman titles. Accompanied by up to seven other players, the player has to collect items and kill enemies in order to unlock new stages. Players were able to communicate with other players through online chat.
