Off The Coast is the third and final chapter of the Master Mode Tale in Bloons TD 6, introduced in Version 57.
Master Mode brings back the classic Mastery roundset with an additional challenge: Bloons have extra layers or fortification, making the rounds considerably more difficult than their standard versions.
How to Beat Off The Coast
Step 1: Build Your Starting Defense
Start by placing your towers in positions where they can cover as much of the track as possible.
Off The Coast offers useful water placement areas, so take advantage of them when building your defense.
Step 2: Upgrade Your Main Damage Towers
Prioritize upgrades that provide reliable damage against the stronger Bloons in Master Mode.
Avoid spreading your money across too many towers before establishing a strong main defense.
Step 3: Prepare for Fortified Bloons
As the rounds progress, the additional layers and fortification become increasingly important.
Make sure your defense has enough damage and pierce to deal with groups of stronger Bloons, while also preparing for MOAB-class enemies.
Step 4: Strengthen Your Defense
Continue upgrading your main towers and add supporting towers when necessary.
Use the available water space effectively and make sure your defense can handle both regular Bloons and the tougher MOAB-class waves.
Step 5: Complete Off The Coast
Keep strengthening your defense until you clear the final round.
Completing Off The Coast finishes the three chapters of the Master Mode Tale.
