Bloons TD 6 inside Subnautica: real BTD6 monkeys vs. Subnautica's sea life, layer by layer, up to a Reaper Leviathan MOAB.
Bloons TD 6, played inside Subnautica. Press the new BTD: 4546B button on Subnautica's main menu to defend a winding track through the Safe Shallows.
The Dart Monkey, Tack Shooter and Bomb Shooter use their real models, portraits, upgrade icons and sounds, read from your own Bloons TD 6 install while you play. Each monkey has two upgrade paths up to tier 3, from Sharp Shots and Triple Shot to Hot Shots, Blade Shooter, Really Big Bombs and the MOAB Mauler. BTD6's crosspath rule applies: one path can reach tier 3, the other tier 2.
The bloons are Subnautica's own creatures, and each one pops into the layer below, just as bloons do:
| Bloon | Creature | |---|---| | Red | Peeper | | Blue | Boomerang | | Green | Bladderfish | | Yellow | Hoopfish | | Pink | Spadefish | | Black | Eyeye | | White | Spinefish | | Purple | Jellyray | | Lead | Gasopod | | Zebra | Stalker | | Rainbow | Mesmer | | Ceramic | Bone Shark | | M.O.A.B. | Reaper Leviathan |
Black and Zebra shrug off explosions, Lead needs bombs or Hot Shots, and Purple can't be burned.
The rounds follow Bloons TD 6's standard rounds 1–40 and end with the Reaper Leviathan MOAB on round 40. You play by BTD6's Easy rules: $650, 200 lives and Easy prices. Round 40 is a tough finale: spread your towers out, and bring sharp ones for the explosion-proof Zebras inside the MOAB.
Solo play. Matches aren't saved.
Not in this version: camo and regrow bloons spawn as normal bloons, since no tower in this version can detect camo.
