Want to crush your enemies in Last War: Survival? Then you need to master the Alert Tower! This crucial building keeps your base safe. Also, it reveals your opponent’s secrets. Let’s dive into how to maximize its potential.
Understanding the Alert Tower 💡
The Alert Tower is your first line of defense. It’s available once your Headquarters reaches level 10. Essentially, it acts as a radar. It detects incoming troops and protects your intel. Upgrading it boosts your scouting abilities. Besides, it also hides your base details from prying eyes. Therefore, strategically upgrading your Alert Tower is crucial.
How Scout Level and Hidden Info Work Together 🧊
Here’s the deal: your Alert Tower has two key stats. Scout Level determines how much info you gather when scouting. Hidden Info Count reduces an enemy’s Scout Level against you.
- Scout Level: The higher, the better intel you get.
- Hidden Info Count: This stat protects your base. It lowers the effective Scout Level of attackers.
For example, a Level 22 Alert Tower has a Scout Level of 14. It also has a Hidden Info Count of 5. So, an enemy with a Level 22 tower scouting you would see: 14 – 5 = Scout Level 9 intel. Therefore, your base is partly protected.
Important Note: You cannot upgrade the Hidden Info Count until your Headquarters reaches level 22.
