What you do

Outer Accord is a real-time strategy game played in one persistent world. Everything you build stays where you left it.

Real planets

Every world is a sphere you can drive round and build on anywhere. Each rock has its own soil colour and deposits.

Build a colony

Your seed ship hovers over the site while little haulers bring the materials and the structure goes up in phases. Extractors, generators, plants, habitats, depots and workshops.

Keeps running offline

Mines extract, factories build and settlers grow whether or not you are logged in. When you come back, the world has moved on exactly as if you had watched.

Trade and research

The three hub stations trade goods and fuel and post contracts. Research takes you from the starting zone through frontier metals to deep space, and each step needs resources from beyond the next gate.

Real flight

Moves in space are flights, not teleports. Fly your ship, dock at the station, land on a planet and jump through the gates.

One shared galaxy

Everyone plays on the same server, with chat between players. Player-versus-player combat is planned and is not in the game yet.

In this build

Windows may warn that the app is from an unknown publisher, because the game is not signed with a Windows certificate. If you want to check the download, compare its SHA-256 with the value above. Choose More info then Run anyway if you are happy with it.

Early test

Outer Accord is in active development. The world you play in is a test world and will be wiped before launch, so build freely but do not expect your colony to carry over. Models and interface are provisional, combat is not in yet, and things will change from build to build.
