3TC (not an official achievement btw) is similar to 2TC, but you can place down 3 towers and you're required to complete up to Round 140 on CHIMPS. In this scenario, we are using the combined might of the Ultraboost, Tier 5 middle path upgrade of the Engineer Monkey, the Lord of the Abyss, Tier 5 top path upgrade of the Mermonkey & the M.A.D, Tier 5 middle path upgrade of the Dartling Gunner to complete Rounds 6 to 140 on CHIMPS.
