Dartling Gun with Focused Firing upgrade artwork

Focused Firing (BTD5) or Steady Barrels (BTD4) is the first upgrade on path 1 for the Dartling Gun in Bloons Tower Defense 5, and the first upgrade for the Dartling Gun in Bloons Tower Defense 4. It allows the Dartling Gun to shoot much more accurately. For its price, Focused Firing will do wonders, as darts are much less likely to strafe off of their mark. However, it may still miss its shots sometimes.


Description: Greatly reduces spread of the gun.

Cost: $215 (Easy) / $250 (Medium) / $270 (Hard) / $300 (Impoppable)


  • The upgrade icon shows 6 barrels whilst the official artwork shows 4 barrels.
  • The Bloons Monkey City artwork has the similar anger to the Dartling Gun walking on the path in the mobile version of Monkey City. (See below right)
