What does the Intelligence Center approach meter track?

Tutorial text in footage we checked says it reflects the approaching swarm; the wave interface shows which side enemies will use.

How are Outposts different from Core Turrets?

Outpost tooltips in commentary footage describe small caliber machine guns on forward tiles. Separate objectives mention Core turrets mounted on the Core—we treat those as different placement roles, without stat numbers.

Can I play through waves without repairing buildings?

No Room for Error requires surviving three waves with no repairs and no repairs between waves, so repairs are optional but damaged tags still appear in UI we checked.

What happens if the Core loses all integrity?

The End of Everything is described as triggering when you lose the Core. Reboot requires restoring Core integrity after durability drops to 10%.

Defending Waves in Wall World Strategy: Turrets and Intel

Defending waves in Wall World Strategy builds on the first Zyrex attack Outpost goal. Assaults can show multiple approach directions in footage we checked, and tutorials warn about electricity crises when consumption beats generation. This page records what UI and achievements confirm about Outposts, Core Turrets, intel tools, power wording, and repairs—without quoting unverified range, cost, or DPS numbers.

How should I use the Intelligence Center during waves?

When a scenario pushes defense, tutorial text in the DeepSpaceMatt playthrough we checked states that the Intelligence Center surfaces an approaching swarm, asks you to monitor the approach meter, and points you to the wave interface for enemy approach directions.

UI piece	What footage or tutorial text showed
Approach meter	Tied to the approaching swarm (Intelligence Center tutorial).
Wave interface	Lists approach sides on the Wall map.
Countdown clock	One example read 1 day and 4 hours to the next swarm on a separate playthrough.

Steam’s Flying Blind achievement requires completing a scenario without building an Intelligence Center, so the building is optional. The Official FAQ still describes procedurally generated Zyrex waves in Sandbox, so waves continue outside the story timer.

Where do Outposts belong on the Wall face?

Outposts are forward defenses. Tooltip text in the DeepSpaceMatt playthrough we checked calls them buildings with small caliber machine guns that attack enemies within range. The same campaign flow that covers your first Zyrex attack asks for two Outposts in a recommended defensive strip before the first swarm.

Footage we checked places Outposts inside highlighted defensive zones when objectives supply them, and the wave interface shows bearings before contact. After combat, structures can show a damaged state, and tutorials prompt building a Repair Shop when damage piles up.

The same commentary playthrough also shows early Outpost placement without an immediate grid extension, then later marks a defense tile as needing power. We could not verify a single rule that covers every wave and difficulty.

If a turret goes dark, see power and electricity for crisis wording and grid coverage in tutorials we checked.

When does Core Turrets research appear?

Core Turrets are distinct from frontier Outposts in verified objectives and voice lines that mention researching Core turrets and mounting guns on the Core. We do not copy third-party guides that list fixed turret counts. Artillery Cannon and Energy Dome names also appear in gameplay footage we checked, without verified numeric stats in this article.

How do electricity crises interact with turrets?

Tutorials in the DeepSpaceMatt playthrough describe an Electricity crisis when consumption exceeds generation, warning that continued overload can cause widespread outages and shut buildings down. Other footage includes narration about unpowering buildings when demand outruns supply. Steam’s hidden Tripped Again achievement tracks allowing 20 emergency power outages, which confirms that wording exists in the shipping build.

We could not verify megawatt thresholds or a single UI rule for every turret tile. If the grid looks positive but a gun still drops offline, treat that as an open case rather than a fixed formula.

What should I do right after a wave ends?

Footage we checked shows Storm attack repelled (or similar) with a duration readout. Tutorials then steer players toward a Repair Shop after researching Repair Workshop; the Damaged Buildings list shows what cracked during the wave. Reboot and The End of Everything on Steam describe Core integrity recovery at 10% versus losing the Core entirely.

Worker reassignment after sieges is covered in workers and jobs. Research pacing between waves is on research order.

How does this tie to named Zyrex types?

Steam lists hidden Bombardier, Swarm Queen, and Rock-Thrower kill quotas at 25 each, plus Exterminator totals for all Zyrex. Commentary footage shows some giants dwarfing Outposts, but we do not map silhouettes to those achievement names. See Zyrex overview and hidden achievements.

What we have not verified yet

Artillery range, Energy Dome coverage, or Core Turret arcs (single-stream UI reads only).
Whether every Outpost must be on the power grid for every wave and difficulty.
Fortified Outpost / Mechanized Outpost as official English build-menu names in release footage we reviewed.
