SteamAbout Wayward Cosmos
A galaxy grown from a single seed
Wayward Cosmos generates everything at runtime: the spiral galaxy of ~120 star systems, every ship hull, planet, station, asteroid field, nebula, enemy, weapon, and item icon. Enter a seed and the exact same universe is rebuilt, share it with a friend and you are exploring the same worlds.
You start near home with a small ship and a handful of crew. The farther you fly from home, the higher the threat: pirate wings grow bigger and smarter, but bounties, loot, gear quality, and salvage climb with them. Reaching the deep-space regions where top-tier "Proto" and "Relic" equipment appears is the long game; surviving the trip is the challenge.

Steam co-op
Play the galaxy with friends over Steam lobbies and invites, no external servers. The host's seed rebuilds the identical universe for every guest, and a peer-to-peer trade system lets pilots exchange goods directly.
Every run is yours
Save your favorite generated ships to a 50-slot launch collection, keep an atlas of galaxy seeds worth revisiting, and reroll a whole new universe whenever you like. A seed-driven galaxy, every world procedural.
