Quick Answer

Good defense in Build a Gun Army means your automatic guns kill enemies before leaks reach the base. Start with coverage, then add DPS where the wave actually fails.

Defense problemBest fix
Small enemies leak oftenAdd more steady-fire weapons or cover the weak lane.
One tanky enemy survivesUpgrade single-target damage or add burst.
Waves clear slowlyImprove the weapon firing most often.
Offline defense feels weakTrack what happens after leaving and returning.

Lane Coverage

Watch the path instead of only the shop. If enemies survive in the same area every wave, that is your first upgrade target.

  1. Identify where the first leak happens.
  2. Add firepower before that point.
  3. Recheck after one full wave.
  4. Upgrade only if the same problem remains.

Offline Defense

The Roblox description confirms that guns fire automatically and defend offline. It does not publicly confirm the exact offline reward formula.

Track:

  • Time away from game.
  • Coins or rewards before leaving.
  • Coins or rewards after returning.
  • Weapons active before leaving.
  • Whether wave progress changed.

What to Verify Next

The best defense page should eventually include screenshots of base layout, wave number, weapon setup, and before/after results. Until those are collected, avoid claiming a permanent "best base" layout.
