// The game
SEIZE THE ELYR.
KEEP IT. OR TAKE IT BACK.
In 2084, humanity has exhausted its resources. One last hope hides in a virtual, brutalist city: the Elyr, the vital energy that can change everything.
You play a champion across tense 5-minute rounds. In 1v1, one carries the Elyr and must hold it, the other hunts relentlessly to tear it away. Two rules clash: in Final Pulse, whoever holds the Elyr when time runs out wins; in Core Charge, you must hold it for 3 minutes total. And for the group brawl, Free-for-all unleashes up to 4 players in a free hunt. Slide, leap, swing on your grapple and trap your opponent with shooting and betrayal items. Reflexes, reads and anticipation will be your only weapons.
SYNTHOPOLIS · THE CITY
Grapple & momentum
Two grapples to choose from: the swing to chain curves and keep your speed, the boost to launch yourself from point to point. Easy to pick up, dizzying skill ceiling.
Zero pay-to-win
Free, and it'll stay that way. 100% cosmetic monetization. Every champion equal at the starting line. Your wallet never wins for you.
Low-spec optimized
Built to run on modest setups, no war machine required. Competition with no hardware barrier, open to as many players as possible, emerging markets included.
Pure competition
From the 1v1 duel to the 4-player Free-for-all. Short, tense rounds, two rules (Final Pulse and Core Charge), zero downtime. A pure test of skill where every millisecond counts.
