Wall
More actions
The Wall is the primary defensive fortification in Whiteout Survival. It protects your city from enemy attacks and must be breached or destroyed before enemies can attack your Furnace or inner buildings directly.
Overview
The Wall serves as the first line of defense for your city. When enemy troops attack, they must first defeat your Wall and any garrisoned defenders before reaching the interior of your settlement. Upgrading the Wall significantly increases its durability and the effectiveness of any troops stationed behind it.
Wall Stats
The Wall has several key attributes that scale with upgrades:
| Stat | Description |
|---|---|
| Wall Durability | Total HP of the Wall structure — how much damage it can absorb before being breached |
| Garrison Capacity | Number of troops that can be stationed inside the Wall for defense |
| Defense Bonus | Percentage buff applied to all defending troops fighting behind the Wall |
Garrison System
Troops stationed at the Wall act as defenders. When your city is attacked:
- Enemy troops must first defeat the Wall garrison
- Defenders receive a defense bonus from the Wall structure
- Once all defenders are defeated or the Wall is destroyed, enemy troops attack the city interior
- Garrisoned troops that survive earn no attack kills but protect your city's buildings
Upgrading the Wall
Each Wall upgrade:
- Increases Wall Durability (more HP before breach)
- May increase Garrison Capacity
- Requires meeting Furnace level prerequisites
- Consumes Wood and Coal
Keeping the Wall upgraded is especially important before events like State vs State, where your city may be targeted repeatedly.
Wall Repair
If your Wall is damaged or destroyed in an attack, it can be repaired using resources. Severely damaged Walls reduce your city's defensive capabilities until repaired.
Troop vs. Wall Defense Strategy
Some players prefer to not garrison troops in the Wall and instead use a peace shield during vulnerable periods. The reasoning is:
- Garrisoned troops can be killed, causing permanent losses
- A shield prevents the attack entirely at no troop cost
- Conversely, in events where shields are unavailable, Wall garrisons are essential
Tips
- Keep the Wall upgraded: A higher-level Wall has dramatically more HP and garrison capacity — it's worth regular investment.
- Garrison your best defensive troops: If you expect attacks, station your toughest units in the Wall garrison.
- Repair immediately after attacks: A damaged Wall leaves your city vulnerable — repair it as soon as possible.
- Use peace shields wisely: Shields cost resources but prevent all attacks; combine with Wall garrison for maximum protection.
- Alliance reinforcements help: Alliance members can send reinforcing troops to boost your Wall garrison. See Embassy.
