About the Game

BECOME THE FASTEST CHAMPION Forget gravity. In Synthopolis, speed is your greatest weapon. Compete online against other players as you race through a vertical cybernetic megacity at breakneck speeds. Every millisecond counts, every turn must be perfect. Will you set the pace?

ONE GRAPPLING HOOK, PURE SKILL, ZERO HANDHOLDING The grappling hook is the core of your gameplay. It's not just a tool; it's an extension of your reflexes. Learn to maintain momentum, calculate your angles, and chain slides. Easy to pick up, but with a massive skill ceiling.

PURE COMPETITION & 100% FREE TO PLAY No shortcuts, no credit cards. Synthopolis is completely free and built for healthy competition. All champions are on equal footing. To claim the city's vital energy (Elyr) and climb the ranks, you will have to rely solely on your reflexes.

AN ALMOST... LIVING ENVIRONMENT You run to save Earth in 2084, but the arena you cross hides heavy secrets. Synthopolis' shifting architecture feels almost organic. Can you tame this parallel world while crushing the competition?
