ZERION: INFINITE SPACE Pilot your starship across an infinite, procedurally generated galaxy. Explore 4,096-unit sectors on an endless grid, trade with neutral merchants, raid hostile fleets, and stake permanent claims on the sectors you can defend. Free to play, with no pay-to-win combat upgrades. WHAT YOU CAN DO โ€ข Explore the infinite grid โ€” every sector is generated on demand from a seed: planets, asteroid belts, comets, warp gates, and ruin sites, all procedural and all persistent. โ€ข Pick a civilization โ€” 15 playable races, each with its own hull silhouette, lore, and faction palette, from the disciplined Terran Commonwealth to the silicate Tharix Cabal to the time-weaving Chronos Seers. โ€ข Build a fleet โ€” 7 pilotable ship classes from light Scouts to capital Motherships. Mix and match 54+ weapons, 37+ shields, and 23+ engines to suit your playstyle. โ€ข Hold ground โ€” claim a sector, garrison NPC defenders, and run the shop economy at a discount. Rival pilots can siege your station; survive the siege window and the sector stays yours. โ€ข Trade and craft โ€” 22 resource tiers feed a player-driven marketplace and a crafting tree of weapons, shields, drives, and consumables. โ€ข Real-time fleet PvP โ€” coordinate with friends, run garrison ops, and siege rival claims on the open server. Combat is twitch-based and server-authoritative. FREE, FAIR, AND YOURS Zerion is free to play, with no pay-to-win combat upgrades. Premium accelerates progression โ€” 1.5x XP, unlimited direct warp jumps, exclusive deep-ring worlds, and extra civilizations โ€” but PvP stays parity-balanced: at equal level, every duel is decided in-sector, not at the store. Play on iPhone and iPad, or in any browser, with cross-progression that keeps your pilot identical across your devices. The galaxy is open. Stake your claim.
