Master pure speed in this ultra-fast, 100% free competitive parkour game. Two grappling hooks, one vertical megacity: swing, chain acrobatics, and hold the Elyr against a rival hunting you down. Climb the global ranks. No Pay-to-Win, only your skill matters.
BECOME THE FASTEST CHAMPIONForget gravity. In Synthopolis, speed is your greatest weapon. Compete online as you race through a vertical cybernetic megacity at breakneck speeds. Every millisecond counts, every turn must be perfect. Will you set the pace?
TWO GRAPPLING HOOKS, ONE SET OF REFLEXESThe grappling hook is the core of your gameplay — and you carry two of them, swappable in mid-air:
- The Swing hook reaches further and keeps every bit of momentum you have built. Anchor, arc, let go at the right instant, and the ground never gets you back.
- The Tract hook trades speed for precision: it cuts your velocity and pulls you exactly where you aimed.
Knowing which hook to fire, and when, is what separates a good run from an untouchable one. Layer wall running, sliding and climbing on top: easy to pick up, with a massive skill ceiling.
TWO WAYS TO WIN- Final Pulse — one shared countdown. Take the Elyr, keep it, and survive until the clock hits zero.
- Core Charge — no time limit at all. Every second you hold the Elyr charges your core. Fill it and the round is yours. Lose the Elyr and your progress freezes exactly where it stopped.
ITEMS DON'T WORK THE SAME FOR BOTH SIDESThe arena is scattered with items, but holding the Elyr forbids you from using them — you can only pick them up. Every one you take is one less for the players chasing you. They use theirs freely: reveal your position, muddy their own, double their firepower, or cut your grappling hook clean off. Running away is already denying.
RUNNING ISN'T ENOUGH — YOU'RE ARMEDA clean hit cuts your target's grappling hook and pins them in place. It is brief, and it is long enough to take the Elyr back. Aiming mid-sprint, at the end of a cable or coming out of a slide means working with your momentum instead of against it — and knowing when to trade speed for a shot.
PURE COMPETITION & 100% FREE TO PLAYNo shortcuts, no credit cards. Synthopolis is completely free and built for healthy competition — every champion on equal footing. Each match feeds a global Steam leaderboard: ranking score, wins, losses, matches played.
SEE WHERE YOU STAND, LIVEThe menu shows the global top 10 and your own position around it, on demand, straight from Steam's servers. Two separate leaderboards, one tap apart — one for ranked play, one for Speedrun — because running alone and hunting a rival aren't the same game.
RUN ALONE, RACE THE CLOCKNot in the mood to be hunted? Take the city on your own. Speedrun mode scatters ten objectives across Synthopolis and times you to the millisecond, with its own leaderboard and your personal best kept on Steam. No hunters, no items — just you, the map and the clock.
AN ALMOST... LIVING ENVIRONMENTYou 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?
PLAY IN YOUR OWN LANGUAGESynthopolis is fully translated into 11 languages — English, French, Spanish, German, Italian, Portuguese, Russian, Korean, Chinese, Japanese and Arabic. Menus and HUD: everything.
