Last War Survival Alert Tower Guide: Introduction
Last War Survival Alert Tower is a vital structure unlocked at Headquarters level 10, acting as your base’s early warning system. It detects incoming scouts and attacks, giving you critical time to respond. Upgrading the Last War Survival Alert Tower boosts your scouting range and accuracy while concealing key base data from enemies. This guide covers its core functions, upgrade benefits, and how it strengthens both your defense and recon strategies in the fight for survival.
Last War Survival Alert Tower Guide: What is the Alert Tower?
The Alert Tower in Last War: Survival is a critical defensive structure unlocked at Headquarters level 10. Acting as an advanced radar system, it detects incoming enemy troops and provides early warnings, allowing players to prepare for attacks by reinforcing defenses or repositioning forces in time.
As the Last War Survival Alert Tower is upgraded, it gains enhanced capabilities—offering more detailed intel on enemy activity and concealing more of your base’s information from enemy scouts. This dual role makes it an essential asset for both defending your base and planning effective reconnaissance missions.
Last War Survival Alert Tower Guide: Understanding Scout Level and Hidden Info Count
In Last War: Survival, the Scout Level and Hidden Info Count determine how much intelligence you can gather—or conceal—during scouting. Upgrading your Alert Tower raises your Scout Level, letting you uncover detailed enemy data like squad power, unit buffs, gear, and more. However, the enemy’s Hidden Info Count, also tied to their Last War Survival Alert Tower level, reduces your effective Scout Level, limiting what you can see.
For example, if your Scout Level is 14 and the enemy has a Hidden Info Count of 5, your effective Scout Level becomes 9—restricting the intel you receive. Importantly, Hidden Info Count starts at zero until HQ Level 22, meaning you can’t hide information from scouts until reaching that milestone. Mastering this balance is key to smart recon and strong defense.
Last War Survival Alert Tower Guide: Upgrading the Alert Tower
Upgrading the Last War Survival Alert Tower is crucial for both offensive and defensive strategies. It requires a significant investment of resources, including Iron, Food, Coins, and eventually Oil as you reach higher levels. The exact amounts of resources required for each level are provided in the upgrade details, but keep in mind that research and bonuses can slightly reduce the actual cost of upgrading.
| Upgrade Benefit | Description | Max Value / Key Milestone |
|---|---|---|
| Anti-Scout Probability | Increases the chance of detecting enemy scouts trying to gather intel on your base. Starts at 0% and grows with each level. | 100% at Alert Tower Level 5 (remains constant afterward) |
| Hidden Info Count | Reduces the effectiveness of enemy scouts by subtracting this value from their Scout Level. | Starts at HQ Level 22, maxes at 5 |
| Scout Level | Determines how much intel you can gather from enemy bases. Higher levels reveal more detailed info (e.g., gear, unit stats, hospital capacity, etc.). | Increases with each upgrade |
| Recon Plane Speed | Boosts the speed at which your scouts return with information. | Improves by 1% per level up to level 11 |

Upgrading the Last War Survival Alert Tower beyond level 30 requires your Warzone to reach the Age of Oil, unlocked during the Season 2 Celebration. You must also complete the HQ Expansion research in the Age of Oil tree to unlock levels 31–35.
These upgrades offer major boosts to scouting and base defense but come with steep costs—requiring large amounts of Iron, Food, Oil, and longer upgrade times. Careful resource planning is essential to balance these powerful improvements with your overall base development.
