Quantum Redshift is a futuristic racing game for the Xbox console, developed by Curly Monsters and published by Microsoft Game Studios in 2002. Created by Wipeout designer Nick Burcombe, the game puts the player in the shoes of 16 different characters, paired off in rivalries, whose stories unfold as tournaments are completed. The game has five different speed limits, which act as the difficulty levels for the game (Novice (Max speed about 300 km/h), Amateur (max speed about 400 km/h), Expert (max speed about 600 km/h), Master (max speed about 800 km/h) and Redshift (max speed about 1300 km/h)). Points earned after races allow players to upgrade their hovercraft's offensive and defensive capabilities. The game featured a soundtrack by Dutch musician Junkie XL.
While featuring 16 different characters, critics generally noted that there wasn't anything particularly "likable" about the characters.
Despite the critical response to Quantum Redshift being positive, garnering 76% at GameRankings, the game sold poorly. As a result, the second game, which was to include play over Xbox Live was cancelled by Microsoft, and Curly Monsters closed shop shortly thereafter.
The biggest selling point of Quantum Redshift was the graphics detail it possessed. Water and glass would show real-time reflections, each of the game worlds were abundant with high-resolution textures, and the camera "lens" would be flecked with water droplets after being submerged. Quantum Redshift was rated as one of the most graphically advanced games for the Xbox.
