Endless
There is no level cap
XP needs grow exponentially and monster levels never stop climbing. The endgame is wherever you are brave enough to walk.
Free endless cyberpunk MMORPG · in your browser
Walk out from Largo do Trilho.
Level forever.
Explore, fight and loot your way through a free cyberpunk RPG. Build your survivor alone or with friends in Véspera, a São Paulo-inspired city that redraws its streets every hour.
No download, no account. Desktop and phone. Your saves stay in this browser.

The hour
Every hour-world has its own streets, monster roster, drop tables, anomalies, loot caches and one to three rare MVP bosses. Nobody has walked it before you.
Read the hour's threat report, buy from the Camelô, talk to the class NPCs, then pick a direction. The plaza is safe. Nothing past its ring is.
Monster levels climb the farther you go: the city ring, the outskirts ruins, the wastes and the unbounded Deep Crater. Every kill drops loot for you alone.
Core Zero starts the rewrite. Bank what you found, see the hour recap, and wake up on the plaza of a city that did not exist a minute ago.
What makes it different
Endless
XP needs grow exponentially and monster levels never stop climbing. The endgame is wherever you are brave enough to walk.
Loot
Every weapon and armor piece comes from a monster. Legendaries hit 10% harder than the regular weapon and burn on your sprite.
Together
Damage a monster, heal or shield someone fighting it, and you get full XP and your own loot roll. Revive downed survivors for bonus XP.
Zero Ops
Purge a nest, hold a relay, hunt a rogue or recover data cores. Anomalies with real effects, elite affixes, MVP phases and enrage timers.
Combat
Hold to attack in reach, dodge telegraphed bites, cast five equipped skills from a growing book. Melee, ranged and magic all read differently.
Progress
A bestiary that fills in as you meet things, achievements with wearable titles, three save slots with export and import, English and Portuguese.
The classes
Choose your class before your first fight, with its starting abilities ready to use. Feed on enemies, command machines, push your heat limit or crash an infected network. At level 50, specialize further.
STR / AGI · Dr. Pestana
Feed on enemies to grow biomass. Spend it on regeneration or a killing frenzy. Stolen code grows a temporary mutation.
Predator · ReclaimerSTR / INT · Scrapper's Workshop
Place turrets and mines, move your machines into position, then sacrifice them in an explosion. Install stolen code to strengthen your drones.
Demolisher · Drone LordAGI / INT · Shelter Armory
A survivor rebuilt with a synthetic combat frame. Heat powers your weapons until they overheat. Switch configurations and vent at the right moment.
Marksman · SentinelINT · Relay Booth
Infect enemies and connect a network. Spread it with stolen code, then trigger Cascade to crash every linked target together.
Phantom · OracleInside the game
