Monkey Avenger League

Monkey Avenger League is an achievement in Bloons TD 6 introduced in the initial release. It is achieved once the player completes 4 games with 4 different heroes. The reward for completing Monkey Avenger League is 100.

Summary
Monkey Avenger League is a trivial achievement. However, it requires the player to unlock 4 heroes due to it's condition. The player can just unlock the 4 base heroes or use Monkey Money to unlock more heroes, however this isn't recommended as most heroes are very expensive for newer players. The reward is a nice amount of Monkey Money for newer players to use, as newer players generally have a low Monkey Money count.

Tips

 * Playing on the map Logs on Easy Standard 4 times with different heroes should work.
 * As stated above, the player should level up until they unlock all 4 base heroes instead of purchasing heroes with Monkey Money, due to how expensive heroes are, especially the recently released heroes such as Psi and Etienne.

Trivia

 * When using mods to place more than one hero at a time, it is possible to get the achievement in one game. This is likely because of the way BTD6 checks the code
 * [UNKNOWN:_PLEASE_VERIFY] The game checks to see if a Hero is on the map once the game is complete. If there is a hero on the map, it adds one to a "list". This list is the percentage of achievement completion. When you place more than one hero in a game via a mod, it checks both Heroes if they are different from each other and adds them to the list separately.
