Assaults

Assaults (BMC)
Assaults are modifiers added on certain tiles in Bloons Monkey City. They come in two varieties - regrow and camo assaults. Each type will increase the number of the respective bloon modifier dramatically.

No tile will have both regrow and camo assaults, but in Monkey v Monkey, it is possible to send an attack with both assaults enabled.

Appearance
Ceramic tiles and under will show the same bloon, but as a regrow or camo variety.

MOAB tiles and up will show the MOAB-class bloon, but with a red regrow or green camo bloon next to it and a plus symbol.

When an assault tile is played for the first time, a warning will pop up, warning the player of the assault.

Monkey v Monkey
Assaults can be added in Monkey v Monkey, at a cost of 10 Bloonstones for Camo and 15 Bloonstones for Regrow. It is possible to enable both, at a cost of 25 bloonstones. Note that you must have researched regrow or camo for the respective assault to be applied to the attack.

Trivia

 * Assaults always increase the difficulty of a tile by one pip. (Easy to Medium, Hard to Very Hard etc)
 * This is why there are no trivial regrow or camo assaults, as there is no difficulty below trivial.
 * Most early players find camo assaults tougher, but high-level players find regrow assaults tougher because high-level regrows will multiply as well as grow.
 * The lowest tile type eligible for regrow or camo assaults is Pink.
 * Assaulted tiles will always contain the highest type of bloon with the camo or regrow modifiers (excluding MOAB-class tiles), as opposed to the usual case of the highest regrow or camo bloon being one rank lower than the highest bloon or lower. (Camo Leads can appear on Rainbows, Camo Ceramics can appear on MOAB tiles)
