announcing Sonic Jump Fever
, a brand new title coming this summer as a free download to iPhone, iPad, iPod touch and Android devices. In Sonic Jump Fever, players compete for high scores in fast vertical jumping challenges. Playing as Sonic, Knuckles, and a host of other characters, friends blast each other's scores by pulling off huge combos and quickly deploying boosters, upgrades, and unique character abilities. Quickly earning points unleashes Fever Mode and puts the player into hyper-speed for earth-shattering scores.
To keep the competition burning, twice a week, playable levels automatically move up to the next zone for all the players. Each time, all scores get reset and players have a new chance to battle their friends for leaderboard dominance.
