What is the robospider in Wall World Strategy?

It is the mobile mining and exploration rig attached to your vertical colony. Footage shows it harvesting metal, minerals, and biomass while separate from city worker job counts.

How do wall expeditions start?

After researching the expedition line, you build an Expedition Center. Its tooltip says it grants access to the wall beyond the city, and dispatch text describes squads exploring the wall.

What is Technopark for?

Narration and building text describe Technopark as the place that produces spiders and modules after you research robospider repair following the crash landing.

Can two expedition teams run at once?

The On All Fronts achievement requires sending two expedition teams to explore the Wall at the same time, so the game supports parallel teams once you unlock the capability.

Wall World Strategy Robospider Guide: Expeditions

This guide covers robospider mining, Technopark, Expedition Center, and achievement-backed upgrades, with links to economy and defense basics and without spoiler-heavy campaign endings.

What does the robospider do in your colony?

Official Steam screenshots and gameplay footage show the rig on the cliff beside modular factories. In those captures:

It harvests metal, minerals, and biomass markers on the wall.
Miners attached to the spider are not the same headcount as workers / miners / engineers inside the city (workers and jobs).
Commentary references extra miners on the spider while city jobs stay full (t71evun6cd8@19:58).

Keep roads and power ready at the Core so surface posts you unlock later snap into the same network (beginner guide).

What happens after the crash?

Narrative scenes show a damaged robospider inside the Core district after impact. Players must research robospider repair and build Technopark (spoken as Spider Robot Tech Park) to restore production. Technopark tooltips in footage say it produces spiders and modules (-H4tjMjf-kM@16:53).

Until Technopark is online, the spider stays damaged in narrative scenes; Laboratory research gates robospider repair in the tutorials we checked (research order).

How do Expedition Center and wall expeditions work?

After the expedition research line completes, you construct an Expedition Center. In P1oPvwC3b7Q@44:20 footage, its English tooltip says it grants access to the wall beyond the city once you finish the associated research expedition step.

Dispatch audio and UI text include lines such as Squad dispatched… exploring the wall, and event cards name locations like Crash site or Glowing fissure in P1oPvwC3b7Q@44:55–50:32. Spiders can enter caves along the wall for mining or scouting (e_DdRHob1T8@02:45).

Achievements that define expedition scope

Achievement	What Steam verifies
On All Fronts	Send 2 expedition teams exploring the Wall at the same time
Trailblazer	Visit every biome on the Wall
Nothing Left Unexplored	Explore every location on the Wall Map in any scenario
Steel Swarm	Operate 8 robospiders in one city (achievement text)

Expedition buildings and city production share the same Power Grid in tutorial footage (power and electricity).

How do robospider modifications work?

The Robospider 2.0 achievement fires when you modify a robospider for the first time. Technopark-produced modules supply those upgrades according to tutorial voice-over.

Spoiler: ultimate module pair (achievement names only)

The Ultimate Machine achievement requires equipping a robospider with both Storm-Bulwark Hull and Singularity-Generator on the same machine, per the Steam achievement text. We have not verified acquisition order or scenario locks beyond that wording.

Day One patch notes mention new movement audio when spiders receive orders, enter caves, or return to Technopark—useful feedback when juggling multiple rigs.

How do expeditions interact with Zyrex defense?

Swarm countdowns still run while expeditions are active in the footage we checked (Zyrex overview, defending waves). Tutorials also pair Intelligence Center setup with wave-direction prep before heavy exploration pushes.

Mining Outpost research lets you exploit remote soft soil veins without moving the whole city (first Zyrex attack timing).

What we have not verified yet

Exact Technopark recipe list and build costs.
Spider miner cap (mentioned in a Steam developer reply; we did not confirm the number in the game UI).
Loot tables or combat stats on expedition events.
Whether expedition map fog matches campaign vs sandbox (sandbox and difficulty).
Leviathan observation targets tied to expeditions (narrative strings only; see achievements list for story spoilers).
