Building and Managing Your Colony

Wall World Strategy is a colony sim on a sheer vertical surface, and that single fact drives everything about how you build. You are not arranging a flat grid. You are working with a narrow vertical band, and the space you spend on one thing is space you cannot spend on something else.

The three-way decision

As your colony grows you have to decide how to expand, which structures to prioritise, and where to allocate resources — and the official framing puts it as a choice between production, housing, and defence. Every settlement you build runs into the same trade-off, and the demo patch notes show the developers tuning exactly these knobs (refined power balance, cheaper concrete defence walls).

Structures the developers have named publicly

Alawar has not published a full building roster, but the official Day One Update patch names several structures by their in-game names while describing fixes to them. These are confirmed names, taken from the changelog:

• Greenhouse — exists in Small, Medium and Large sizes; the patch corrected their size descriptions and adjusted their output values
• Canteen — was not applying production bonuses correctly, and now does
• Hospital — had incorrect size descriptions
• Modular Housing — had incorrect size descriptions
• Statue of the Builder — had incorrect size descriptions
• Faces in the Rock — had incorrect size descriptions
• Stockpile — tracked by a resource achievement
• Core — the heart of the colony; it can be destroyed and it can be recovered

A full and authoritative building list, with costs and unlock conditions, has not been published by Alawar at the time of writing. Everything beyond the names above is best learned in-game or from the Steam Community Hub.

Infrastructure and roads

Roads are a real system rather than decoration. The June demo update shipped simplified road-tile placement, a fixed road-construction animation issue, and an optimised road-placement algorithm — which tells you that pathing between structures was one of the biggest technical problems in development. Stairs matter too: the same patch fixed an issue where removing stairs near the Core broke things, which is why stairs appear in the bug list at all.

Power

Power is managed explicitly and can fail. There is an achievement for reaching an energy surplus, one for running on solar only, and one for surviving 20 power failures. The demo patch also added a fix for a bug that prevented disabling the small energy dome — a structure you can switch on and off — and a fix for miners flying around empty excavation points when resources were not there to collect.

Scale

The population achievements are numbered: first colonist awake, 200, 500, all houses filled. The building achievements are also numbered, up to 1000 buildings. This is a game designed to be played at a considerable scale, not a compact puzzle box.
