Round 90
Round 90 in BTD6: 50 camo regrow fortified Leads and the first 3 DDTs. RBE, cash, DDT counters and how to beat it.
Guide
Round 90 is small but famous. It starts with 50 Leads that are Fortified, camo and Regrow at the same time, then sends the first three DDTs of the standard rounds about 10 seconds in.
DDTs are the problem. Each one has the properties of a camo, a lead and a Black bloon at once, so it needs camo detection and is immune to sharp damage and explosions. It moves faster than other MOAB-class blimps and has about 480 health after ramping. When it pops it drops four Camo Regrow Super Ceramics. The whole round is worth just 2,756 RBE and pays about $149 from pops plus a $190 bonus, but players without a DDT plan lose here all the time.
Bloons in round 90
- 50 × Lead Bloon (Fortified, Camo, Regrow) (0–10 s)
- 3 × DDT (10.4–11.9 s)
How to beat round 90
Build a DDT answer before round 90, not during it.
- Camo detection over your blimp damage: a Radar Scanner village (x-2-x) is the easiest fix. Towers like 2-5-0 Elite Snipers already have detection built into their path.
- The right damage type: the Monkey Intelligence Bureau village (x-3-x) lets every tower in range pop all bloon types, which fixes bombs and sharp towers. Otherwise use towers that pop lead and black naturally: Elite Snipers (Full Metal Jacket), Sun Avatar or Sun Temple with camo detection, and Plasma Accelerator or Ray of Doom Dartlings.
- Bombs alone will not work: MOAB Assassin and Eliminator deal explosive damage, so they need an MIB village to hurt DDTs.
- Slow them: DDTs are quick, so Glue Strike, MOAB Glue and Maim MOAB help a lot.
The Fortified Camo Regrow Leads at the start need the same camo and lead coverage, so if they get far, the DDTs will too. In CHIMPS, this round also previews 93, 95 and 99, which all add more DDTs.

Frequently asked questions

What pops DDTs in BTD6?
Towers with camo detection that can pop lead and black bloons, such as Elite Snipers, Sun Temples and Plasma Accelerators, or any tower near an MIB village with camo detection.
Why do my bombs not hurt DDTs?
DDTs have Black bloon properties, so explosions cannot damage them unless the tower is buffed by a Monkey Intelligence Bureau village.
