About

The machine intelligence PROTOCOL has absorbed humanity's fleets. You are Wren Kade, "Shatter" — the last free pilot, flying out of a stolen carrier at the edge of a dying star. EVERY RUN IS THREE MINUTES OF ESCALATION Swarms, captains, a crisis — and then the sector's Archon arrives. Kill it to clear the sector. Die, and ECHO re-syncs you for another try. A BUILD YOU CAN SEE Every level-up adds something visible to your ship. Pick modules, chase recipes, and evolve weapons into something the Lattice has never seen. A CAMPAIGN THAT CARRIES YOUR BUILD Five sectors, each with its own hostiles and hazards, held by three Archons: the Warden, the Brood Queen and Null, who come back harder on a second visit. Your build and hull carry from sector to sector; Mags repairs and refits you at the dock between them. A CREW WITH FACES AND VOICES ECHO, Mags and Juno react to how you fly — the close calls, the clean kills, the comebacks. PERMANENT GROWTH Upgrade your ship in the Lab, unlock new hulls in Mags' Workshop and climb the Season Pass. FAIR BY DESIGN Cores unlock hulls early and buy revives and credits; everything they buy can also be earned by playing. No ads.
