From Southpeak Interactive: Iridium Runners takes players to the year 2050, where rivalries on the track are no longer settled by vehicle but by feet. Racing at breakneck speeds through a myriad of challenging tracks, players must do whatever it takes to win. Shrinking your opponent, knocking them over as you pass, or setting traps that will fling them over the side and into oblivion are all legal methods of being first across the finish line.
