Submerge and Support is the 3rd upgrade on Path 1 for the Monkey Sub in BTD5 and BTD6. It costs $425 on Easy, $500 on Medium, $540 on Hard and $600 on Impoppable. It adds a new targeting option: Submerge. When selected, it ceases firing darts, however, it will send out green concentric circles that will remove camo from Bloons, including DDTs (both BMCM and BTD6). It will remain submerged until you set its priorities to one of the default (First, Last, Close, Strong).
Note: In BTD5 generation games, the target settings must be changed manually to use the "Submerge" option. Activate the "Submerge" option by clicking "Submerge" down at the left under the icon. In the mobile versions, press the left button from "First" to "Submerge" to activate submerge mode.
- In BTD6, this upgrade automatically submerges the Monkey Sub, while in the BTD5 generation it did not.
