Special Agents Only is a Special Mission in Bloons TD 5. It is unlocked at Rank 30 and reward 50,000 XP (gives 20,000 XP after every following completion) and File:AwesomeIcon.png40 upon completion. You have to complete the first 50 rounds in Switch on Hard Difficulty with only Special Agents to beat this mission. None are provided, making this a very costly special mission in terms of Monkey Money.
