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 โข 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. โข 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. โข 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. โข 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. โข Trade and craft โ 22 resource tiers feed a player-driven marketplace and a crafting tree of weapons, shields, drives, and consumables. โข 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.

Verdict
The clearest difference is in-app purchases: Zerion at none against Gem Slash's 1. Zerion also leads on update cadence (weekly vs every 5 months). Gem Slash's advantage is iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
