Erosion is an Advanced map in Bloons TD 6, introduced in version 37.0.
Layout
Erosion has 6 different paths. Starting on Round 18 and every 18 rounds after, the land will collapse between the current track and the next tracks, selling all land towers on the ice and changing the path to the next lane. Pat Fusty, Mermonkeys, Sun Temples, and True Sun Gods are not sold and transform into water towers when the land under them erodes. The map reaches the top-right lane and stops eroding on round 90, and the round 90+ lane is the shortest lane out of any lane in any map that gives rewards in BTD6. Only Blons has a shorter lane. Heli Pilots cannot fit on the top-right section of this map while Banana Farms could, despite Heli Pilots having the smaller footprint out of the two.
Strategy
Erosion is not particularly difficult outside of CHIMPS mode, as towers sold by the eroding mechanic give back cash. This is not the case in CHIMPS. The eroding mechanic, along with the extremely short length of the round 90+ track, make Erosion generally considered as an Expert-level, mis-categorized map that is only bested by X Factor in terms of the difficulty of Advanced maps. Attempt to place as few towers as possible outside of the top-right in CHIMPS, as they will be sold for no money before the hardest rounds come. For the early game and mid-game, use global towers or towers able to be teleported that can function on the top-right.
Recommended towers and upgrades
| Name | Portrait | Reasoning |
|---|---|---|
| Corvus | His Spirit can pop Bloons from anywhere, and his Spear spell is very powerful throughout the early game. At level 7, he can use Spirit Walk to move to a new lane away from collapsing ice and constantly gain mana. During the mid-game, his Spellbook can save up titanic amounts of money for a solid tower that defeats the late-game, such as Carpet of Spikes and Bloon Exclusion Zone. In the late-game, Corvus still has solid utility with Ancestral Might and Overload. | |
| Carpet of Spikes | It is powerful on this map due to the extremely short length of the round 90+ lane. The short length of that lane allows for extreme concentration of spikes that deal massive damage with every passive & active ability, easily sweeping DDT rounds, doing solid damage to ZOMG shells, and eliminating Round 100's BAD as a problem altogether. Use the 0-5-2 crosspath, as without it, most spikes will be wasted on inactive lanes, and use a MIB or Embrittlement to give it DDT popping power. | |
| Advanced Intel | This upgrade allows Monkey Subs to adapt to lane changes by attacking within the range of other towers. It is primarily used for the early game, with Airburst Darts coupled with this upgrade contributing significantly throughout. |
