About the Game

Infil into the dark sci-fi world of Tau Ceti IV: A derelict colony rife with rival Runners, hostile UESC security forces, and hazardous environments. As you scavenge its zones for valuables with a crew or alone, tense moments of exploration break into fast-paced PvP combat where gunplay is responsive, time to kill is low, and preparation is rewarded.



Exfil to advance your seasonal power, earn cosmetics for your achievements, and assemble stronger builds with your stolen loot. Then put your gear back on the line to seek even greater fortunes in your next run.



A GRAVEYARD OF POSSIBILITIES

Trespass across deserted research facilities, rugged landscapes, and security outposts holding the remnants of a vanished expedition, yours to salvage. Tau Ceti threatens death at every turn with unique enemies, dynamic events, and environmental hazards. Each zone escalates in difficulty, preparing you for the UESC Marathon locked in the heavens.



POWERFUL. CONFIGURABLE. EXPENDABLE.

Six equippable Runner shells offer diverse playstyle foundations to build upon, like Destroyer, Recon, and Thief. Scavenge an arsenal of moddable weapons, body implants, and core system upgrades to craft countless builds. Strategize as a crew each run to form comps that maximize your combined strengths, shaping the way you approach fights and objectives.



ENEMIES EVERYWHERE

Face the unknown as a crew of two or three, or alone in solo lobbies. Or sneak into in-progress crew lobbies as Rook, a lone scavenger with no starting gear and nothing to lose. Forge uneasy alliances with rival Runners in prox chat to defeat mutual foes, but remember your new allies might revert to enemies just as quickly. Be merciless in combat: A lone survivor can reboot their crew, even from death.



Later in Season 1, compete in Rated mode to measure your skill and build a name for yourself.



INFLUENCE IS POWER

Liaise with six competing factions, each offering lucrative incentives to advance their foothold on Tau Ceti. Completing faction contracts grows your baseline power via season-long unlocks like Runner shell upgrades, stronger starting loadouts, expanded vault space, and specialized wares on offer for spare loot.



DEFRAGMENT THE TRUTH

No one knows what happened a century ago when the Marathon expedition went dark. As a trespasser into UESC territory, you are uniquely positioned to piece the story together. Unearth the skeletons of Tau Ceti’s past as you run deeper into the colony.



DEATH HANGS ABOVE

Once the way into orbit unlocks, bring your endgame build to Cryo Archive, the first floor of the UESC Marathon. Solve raid-like security measures to unseal frozen vaults and pillage the artifacts within. Every cramped corridor forces you into conflict with fully-geared enemy crews racing for the same prize. Breach the seventh vault to challenge an entity even the UESC fears.
