User:Qwertyxp2000 the second/Bloons TD Battles 2/Strategies/Intermediate Unlocks

In Bloons TD Battles 2, a novice player should be able to unlock the majority of the important T3 upgrades in the game. Next step for the player is to unlock the most powerful T4 upgrades as soon as possible, which helps to adequately compete against other players who already have an advantage in tower unlocks. The purpose of this page is to guide players towards the milestone of achieving the stage of the game where the "best" Tier 4 upgrades can be unlocked. Starting from Version 1.0.6 (at least upcoming), players in White Wasteland and Lead Dungeon are restricted up to Tier 4 upgrades.

General Strategy
After getting the hang of various loadouts up to Tier 3, it is important to mix strategy with large quantites of gameplay. This helps progress levels for upgrades faster across all towers. Make sure to

You get double XP if you win, and you also get double XP again if you watch an advertisement. With VIP access, which can only be bought with in-app purchases, it gives 4x XP, to which adding a watched advertisement increments it to 5x.

For purposes of this page, this page mainly focuses on sustaining steady XP progression to such a stage that all Tier 4 upgrades are unlocked.

Also, importantly, no Battle Points, Monkey Money, or Trophies will be earned if losing on a super early round. So intentional death games is not a valid strategy for earning anything other than Tower XP.

Try to optimise your loadout pre-game and your defence in-game to defeat all kinds of bloons such as: regen bloons, camo bloons, moab class, fortified bloons, grouped bloons, leads, black and whites, purples, and more.

Heroes and Towers
The best strategy here for defense is to revolve the tower loadout based on the hero. Each hero has their own advantages and disadvantages that will help out as the game goes on. Offensive strength is one aspect to view, but there's also base cost and buffing potential. Assume any hero could appear, so watch out for all types of heroes!

Quincy has a cheap early-game that progresses decently throughout the game, and better than Obyn in the first round. He is good at cleaning up bloons, or just defending against bloons coming from the natural end. He also gains camo detection as he levels up. At this point, it is a good idea to experiment with different towers to see what pairs well for offsetting his grouped-popping and spaced bloon weaknesses.

Gwendolin...

Striker Jones...

Obyn Greenfoot...

Cyber Quincy...

etc.

Important Towers
With the gathered Monkey Money, use it to unlock new heroes, after obtaining all the necessary towers. One can choose not to unlock specific towers first by focusing on one specific hero first before then, which still works. Heroes are very expensive, so focus on mastering one hero first before unlocking any other heroes. Cosmetics should be prioritized later at all costs.

The below table is a recommendations table, ordered by recommended priority to start focusing on unlocking with Tower XP:

Important Upgrades
Applies to upgrades up to Tier 4. Throughout all tower categories: Primary, Military, Magic, and Support. The table below covers important Tier 4 upgrades.
