Bionicle Heroes is a third-person action game where the player takes on the role of the various Lego Bionicle Toa Inika - Jaller, Matoro, Hahli, Kongu, Hewkii, and Nuparu. These heroes wear Toa Masks of Power - power-ups that can be found throughout the levels to gain different elemental based abilities. There are also Bionicle canisters to aid the protagonists on their quest to defeat Vezon - the 7th Piraka who had stolen the Mask of Life.
The gameplay centers around firefights against the alien "robots" called Vahki, Visorak, and Bohrok. Players will collect Lego pieces for every enemy they defeat, and eventually enable an invulnerable Hero Mode to help defeat the Toa's enemies.
