Where It All Begins

Where It All Begin is a special mission unlocked at Rank 80 or by completing at least 1 expert level! taking place in Monkey Lane. This mission is at hard difficulty, with all bloons being completely normal and so does all your towers. Except for one difference, all your towers except Dart Monkeys are locked, and so are all the upgrades, just like the first time you're playing the game. (Rank 1)
