Beast Rizer Plus

Petro-Plus (ペトロプラス), stylized as Petro+, is a 2D action-adventure game developed by Burst Arts Inc. and published by Namco Bandai exclusive for the WiiWare. This game was produced in commemoration of the Petropolis series' 15th anniversary. Because of this, the game homages the original classic games (from the first game to Petropolis 4), featuring fast-paced action gameplay.

Story
The Garage Kids received news about a mysterious gem hidden in the Southeastern Islands. Thunder and Selene took off to search for the stone, but so did five of Whisker's chimera soldiers. As the two heroes saw the five chimeras excavating the gem, it is revealed to be a diamond with unfathomable power. Soon, all of them were thrown into a cavalcade of illusions based on their past experiences, leaving Thunder and Selene, as well as two new faces with incredible skills, to find a way to destroy the diamond.
