Short summaries of each Steam post, with the player numbers Alawar published after the playtest and the demo.
The game was announced as a full colony sim in the Wall World universe, and an open Steam playtest started the same day. That first build had no save system, so progress was lost between sessions.
Manual saves and autosaves arrived, along with better robo-spider and enemy behaviour, easier placement of buildings, roads and foundations, reworked HUD panels and many new models and sounds.
The playtest ended with 12,000 players, a 37-minute median playtime and 20,000 wishlists. Alawar promised reworked foundations, mining, electricity and repairs for the demo.
The demo opened with the new foundation rule: construct a building and connect it with roads, and it works. Electricity and mining were improved over the playtest.
The demo stayed playable for the whole of Steam Next Fest, with a new demo trailer.
The largest patch so far, with 22 changes: simpler road placement, a fix for removing stairs near the Core, miners that collect resources automatically, a cheaper concrete defense wall, refined power balance, a clearer Morale bar and a long list of bug fixes.
The demo closed with over 12,000 players, a 32-minute median playtime and more than 36,000 wishlists. The team named its next priorities: more vertical building, visual refinement and quality-of-life features.
Launch was set for November 11, 2026, with a developer commentary trailer. The post lists five additions for the full version: scenarios across biomes, new challenges and events, an expanded research tree, difficulty settings and Sandbox Mode.
The changes fall into three builds. The demo is closed, so the full release on November 11, 2026 is the next chance to play.
