This video demonstrates the second part of the strategy I use to perfectly win (without losing any lives) the second Intermediate track or Pool track for Bloons Tower Defense 4. No premium upgrades are used (not even the free one) and neither is the save feature. The basic outline for this strategy is blatantly stolen from the following user: www.youtube.com/user/ICantFindADamn, with some differences:
1) I can acquire the BRFs earlier, and without selling anything
2) I get three Rings of Fire before the first Republic (admittedly, this isn't much of a difference)
3) I don't get an Ice Tower before round 49 (this helps save money so you can get the BRF earlier)
4) Pineapples are a crucial necessity for rounds 28 and 30.
Please don't come to this video to hate, if you have a different, better way to defeat this track, then please post a video response. I own nothing, Bloons TD 4 was made by Ninjakiwi! (But ultimately, I play on a different site, because the Ninjakiwi Bloons TD 4 is lagging too much for me these days...)
In Part 1, I put one less Dart Monkey, and more glue. In level 10, I set the two monkeys on the right to Strong priority (but I change them back to First priority at the start of level 11- just a minor detail) , and use glue repeatedly from level 11-25, except in rounds 18 and 24.
