Extreme-G is a futuristic racing game developed by Probe Entertainment and published by Acclaim Entertainment, released for the Nintendo 64 in 1997. Set in the far future, players ride plasma-powered bikes on sci-fi tracks at speeds over 750 km/h. Unique track designs with loops, jumps, and spirals deliver a rollercoaster-like thrill. The game features various weapons like multi-missiles, magnetic mines, and laser mines that players can pick up to attack opponents. Special weapons such as cloaking devices, phosphorous flash bombs, and the "Wally-Warp" add strategic depth. Single-player offers three difficulty levels: Novice, Intermediate, and Extreme. The main "Extreme Contest" mode includes three championships: Atom (4 tracks), Critical Mass (8 tracks), and Meltdown (12 standard tracks). Players must finish first in each championship to unlock new content. Multiplayer supports up to four players in racing, capture the flag, and battle modes. Upon release, it earned positive reviews for its unique track design and high-speed racing experience, achieving commercial success.
