Bomberman GB 2 is the second Bomberman GB game. It was released in Japan in 1995. It was later released in North America and Europe in 1998 by Nintendo as Bomberman GB due to the previous game being released under the title Wario Blast: Featuring Bomberman!.
For the most part, the game plays like a traditional Bomberman game on a grid-like field. Before each new area, the player can select between Mode A and B which is different for every area. The modes create different rules that must be followed in order to clear each level in the area. For example, in Area 1 if the player chooses Mode A they must defeat all enemies. If the player chooses Mode B then they must defeat the monsters in order, according to where the arrow is pointing.
After clearing an area, the player earns a new ability that can help them later on in the game. For example, after clearing Area 1 the player earns the ability to use the whip. They can use the whip to knock bombs away from them (similar to the Boxing Glove's ability).
Indy Bomber has been combing a vast jungle in search of the Ring of Wishes. He discovers a ruins with the jungle and as he is reading a scripture, falls through a trap in the floor. He must find his way out of the dungeon and find the Ring of Wishes.
