Build a colony on the surface of an endless wall. Keep it from collapsing.
Wall World Strategy is a colony simulation game from Alawar, and it takes place on a surface most people would never want to live on: the sheer vertical face of a colossal Wall that stretches past the visible horizon. You are not a lone miner here — you are a settlement overseer. Start from a small outpost, plan where every structure goes, lay out production chains, pull in resources from the depths, keep your colonists fed and housed, and hold off the zyrex that keep coming back for another bite. Then send robo-spiders out into uncharted sectors, because the Wall goes down as well as up, and the good ore is not on your doorstep.
The colony is built on the sheer face of an endless Wall. Space is a vertical strip, not a flat field, so every structure you place is a layout decision you have to live with later.
Send specialised spider machines into uncharted sectors and the depths to extract resources, recover technology samples and find rare artefacts. They work where people cannot safely go.
The zyrex do not stay dead. They raid again and again, and the achievement list names the ones you will meet: Bombardiers, Rock Throwers and a Queen.
Overpopulation, food shortages and supply disruptions tank efficiency and can trigger riots. Population, morale and promises to settlers are real systems, not flavour text.
The Wall is a colossal structure stretching far beyond the visible horizon, hiding traces of ancient eras and unexplained phenomena within its depths. Among stone, metal and darkness, humanity was forced to build a new life, clinging to the Wall and trying to survive in a world full of threats and mysteries.
Wall World Strategy is a colony sim on a sheer vertical surface, where every decision affects the stability of the system. Build and expand your base, gather resources, take care of your people, strengthen your defences, and send expeditions into distant regions and unexplored depths. Each new step forward brings not only opportunities for growth but also new dangers.
The game launched on Steam on November 11, 2026 for $19.99 (€19.99), developed and published by Alawar. It supports Windows and macOS, full controller support and Steam Deck. A soundtrack DLC launched alongside it for $4.24.
The demo opened during Steam Next Fest on June 15, 2026, and closed on July 1. Alawar reported over 12,000 demo players, a median playtime of 32 minutes, and wishlists exceeding 36,000. The demo period is where most of the mechanical tuning happened, and the official notes are unusually specific about what changed.
The achievement list names three campaign difficulty tiers, so the campaign is explicitly selectable: Light, Medium and Hard. Each has its own completion achievement.
Sandbox drops the story constraints and the time pressure. You still get attacked by zyrex, but you set the pace and can experiment with different development and defence strategies, choose from different maps and tailor conditions to your liking.
The colony can collapse, and the achievement names make the failure conditions explicit. There is an achievement for the Core being destroyed, one for saving without using the save system, one for recovering the Core after it falls, and one for a total power failure — you have suffered 20 of them. That is the shape of the risk profile: this is a game where you lose ground, not just minutes.
The campaign has three story chapters (Story 1, Story 2 and Story 3), and side content is tracked separately. Side quests are named in the achievement list: the first zyrex attack, Listener Fate, Refugees, and Core 43. A Wall that has a number attached to it is a place with history.
