Run, jump, swing around, fire rockets, grapple onto people to knock them off screen
Developed by Double Dutch Games for PC and Mac, SpeedRunners is a multiplayer running game in which multiple heroes compete with each other. All action takes place on a single screen, and the goal is to run off of it. You can use weapons and power-ups to slow down your enemies.
SpeedRunners is now fully launched on Steam.
