Round 2
Round 2 in BTD6: 35 Red Bloons and 35 RBE. Bloon list, cash and how to use this easy round to set up your defence.
Guide
Round 2 sends 35 Red Bloons in one long stream over about 19 seconds. It is still a single-layer round, so the only challenge is coverage: the stream is a little longer and slightly tighter than round 1. Like round 1, it is only played on Easy and Medium, since Hard begins at round 3.
By the end of round 2 you will have collected the end-of-round bonus twice, which is usually enough to add a second tower or the first upgrade that defines your early game.
Bloons in round 2
- 35 × Red Bloon (0.0s–19.0s)
Total: 35 bloons worth 35 RBE. Popping everything pays $35, plus the $102 end-of-round bonus.
How to beat round 2
Anything that cleared round 1 clears round 2. The useful question is what to buy next.
- Add a second Dart Monkey or upgrade your first one if your hero is not in range of the whole path.
- On Easy and Medium a Banana Farm bought this early pays for itself long before the first MOAB on round 40.
- If your map has water, a cheap Monkey Sub or Monkey Buccaneer can be bought now and grown into a key tower later.
Keep in mind that Blue Bloons show up on round 3 and Green Bloons on round 6, so a single unupgraded monkey will soon need help.
Alternate Bloons Rounds
The ABR version of round 2 is never played in a normal game, because Alternate Bloons Rounds starts at round 3 on Hard. It can only be seen through custom setups like the Challenge Editor.
- 35 × Red Bloon (0.0s–15.0s)
- 20 × Red Bloon (18.0s–25.0s)
ABR total: 55 bloons, 55 RBE.
