Mega Sentry

All types of Mega Sentries

The Mega Sentries are sub-towers spawned by the Master Builder that makes their first and only appearance in Bloons TD 6.

Mega Sentries are created only by the Master Builder, and are distinguished from ordinary Sentries by their immense sizes and capability to produce their own Modified Paragon Sentries.

There are three Mega Sentries, and each are able to be placed when the Master Builder's ability is activated. One sentry is placed at a time, and follow a set order for placement, starting with Green, Red, and then Blue.

General Information

Each Mega Sentry has its own means of fighting off bloons. The first Mega Sentry placed is the Green Mega Sentry, and it functions similarly to the Plasma Accelerator. It fires a purple beam that follows your mouse and does more damage at the endpoint of the beam. The second sentry is the Red Mega Sentry, which fires plasma at incredible rates. The plasma fired is similar to the Anti-Bloon's projectile, having a distinct red color. The third and final sentry is the Blue Mega Sentry, which fires large blue missiles, similarly to the M.A.D., that do huge damage to blimp and Boss Class bloons specifically.

All three types of Mega Sentry spawn Modified Paragon Sentries every 6 seconds. They last 19 seconds total, and work similarly to the Champion Sentries of the Sentry Champion, firing unstable purple plasma.
