Guide
Round 138 is the biggest DDT round of the first 140. Waves of Fortified DDTs (81 in total) start first, and waves of normal DDTs (45 in total) join from about 21 seconds, all running until 40 seconds.
At ×4.70 ramping, Fortified DDTs have about 3,760 health and DDTs about 1,880. They are camo, immune to sharp and explosive damage, and by now very fast. RBE is 442,872 and the round pays about $1,920 from pops plus a $238 bonus.

How to beat round 138
It is the ultimate DDT check.
- A Monkey Intelligence Bureau village with Radar Scanner must cover every tower you rely on.
- Fast-firing DDT killers (Elite Snipers, Plasma Accelerators, Ray of Doom) and DDT-capable Paragons do the heavy lifting.
- Glue Strike, MOAB Glue and Super Glue slow the stream, and camo-capable area damage cleans up the Fortified Camo Regrow Super Ceramics they release.
