Prepare a working defense before the first wave

To survive the first Zyrex wave in Wall World Strategy, prepare an attack warning, cover the reported approach with turrets, and make sure the colony can power those defenses. Keep essential supplies running while you do it. The first attack is easier to prepare for when a shortage has not already consumed your remaining construction time.

The practical sequence here comes from SplatterCat's early alpha player experience. The official Wall World Strategy Steam page confirms recurring Zyrex attacks, but does not publish a guaranteed first-wave turret count, timing, or release-version build order.

Get the warning and read the approach

In that playtest, the tutorial directed the player to build an intelligence center after scouts reported dangerous creatures nearby. Once built, it displayed a countdown and showed the direction of the approaching attack.

Use that information to decide where to defend. Check the approach before spreading your limited materials over several disconnected positions. The player focused the opening turrets on the indicated route; later waves required attention to additional directions.

If you are using that early build as a reference, remember that the countdown described one particular run. It is not a promise that every scenario gives the same preparation window.

Gather the materials your defenses actually need

The reported opening had enough metal at several points while crystals delayed important buildings. Keep the relevant extraction staffed and producing before spending your reserves on optional expansion.

The player also encountered the nighttime rest period, when production and mining stopped. This made a small material shortfall significant: waiting for a missing resource could mean waiting until work resumed. Check both the attack timer and the work schedule before leaving construction until the last moment.

Maintain water, ration production, and housing during the buildup. In the same run, water and food shortages needed attention before the defenses were finished. A stable colony gives you more freedom to spend the remaining time on protection.

Place turrets and check your electrical margin

The player placed multiple machine-gun turrets near the indicated approach and successfully repelled the opening attack. That demonstrates a workable early-playtest example, rather than proving an exact minimum.

Before letting the timer run down:

  • Confirm your defenses have finished construction.
  • Check that the reported approach is covered.
  • Check available power against the defenses and existing buildings.
  • Keep the supplies needed by the colony producing.

Power became a larger problem as more turrets were added for subsequent attacks. Avoid carrying an already strained grid into the first wave. Once the attack is over, check the next warning; surviving one direction does not establish coverage for the next wave.

FAQ

Is one turret guaranteed to stop the first wave?

The available sources do not establish that guarantee. The tutorial requested a turret in the reported playtest, but the player built several before the first attack.

What does the intelligence center do?

Early alpha player experience describes it revealing the time until the next attack and an approaching-enemy indicator.

Why am I waiting for resources even with workers assigned?

In that early build, production and mining paused during nighttime rest. Check the time, deposit status, and building staffing before deciding that another extractor is needed.

Does this advice guarantee survival on every difficulty?

No. It explains the supported preparation sequence from an early run. Map conditions, difficulty, and changes since that playtest can affect the defense you need.
