Game Description:For those who haven't played Extreme-G, up to four players take control of futuristic, magnetic bikes and race against one another on a variety of planets. While racing is at the heart of the game, there are so many weapons and power-ups that shooting and destruction also become a major part of the gameplay experience. Developer Probe invested a lot of time to add plenty of features, improve the Battle Mode, and up the top-speed of bikes to Wipeout proportions. You can even break the sound barrier and hear a sonic boom that then drowns out all other audio until you slow down below Mach 1. There are 12 different tracks, each with 3 variations, an improved Battle Mode with slow-moving tanks, a multiplayer Cup (up to 16 players compete in two-player split-screen competitions), as well as a contest mode with three cups, three difficulties, plus an added Duel Challenge.
