In Mercury Meltdown Revolution, players guide a mercury blob around futuristic environments complete with moving machinery, test tubes, trap switches, spikes, rotating walkways, dangerous ledges, and other obstacles, in order to reach an end-level goal. The Wii build of the title is set to feature more than 150 levels, hidden labs, updated blog physics, and a variety of bonuses.
