Wall World Strategy

Beginner guide

The opening hours are a short chain of named objectives. I am following the cards visible on the official screenshots, plus achievement rates, not a cycle number someone invented.

The Core is already there. Colonists come out of cryosleep. The achievement New Day, New Life — wake the first sleeper — sat at 62.0% of players on 13 November. Bread and Water, one Canteen plus one Rain-Collector, sat at 83.3%. Food and water are the first pair the achievement list itself names.
First Discovery, finish one research, was at 67.5%. The screenshot objective Awakening of the Machines tells you to research and build the Robospider Technopark, then build a robospider. That is the machine chain, not a guess about an optimal tech order.
On the Front Line asks for two machine-gun turrets. First Onslaught, repel the first Zyrex attack, was at 71.2%. The wave panel on the same screenshot lists 4 flying and 24 ground, with the line “The swarm attacks in: Now”. A different screenshot shows “The swarm attacks in: 13 h”. I do not turn those two labels into “the first wave is on day 8”. Nobody official has published that day.
Shelterless City tracks people without a bed. One screenshot shows 6/124 and a population of 31/134 on day 2. A discussion reply says you choose who wakes from the main-base panel. One source.
A player reply says pause lets you issue orders and place buildings, and construction starts when time runs again. One source. Power sits on the right of the HUD in watts. Early weather on the top chart is often clear for the first two days, according to that same style of player report, so solar and a battery are the opening power plan. Details live on the resources page.
The Day One Update matters on hour one: Canteen bonuses were fixed, and greenhouse size text was fixed. If a canteen looked like it ignored a bonus on 11 November, that was the bug the 12 November note claims to have closed.
Objective cards read off official screenshots. Completion rates are global achievement percentages on 13 November 2026.

Questions

How do I win the first scenario?

The FAQ says there is a story scenario and then endless challenges. First Step, clear the story on any difficulty, was at 12.9%. The page does not list a turn count.

Which building comes first?

The achievement pair is Canteen plus Rain-Collector. That is the only “first buildings” order I will state.
