Infiltration

The Special Mission Infiltration is the battle when you fight T.M.A. Mk. I. It has only 10 rounds. All agents are forbidden. It is Medium difficulty and you start with 8 times as much money. The first four rounds give 5 times as much money as normal, but the following rounds give only half as much.

Rounds
1: 50 Spaced Red Bloons

2: 20 Spaced Green Bloons

3: 2 Pink Bloons

4: 5 Regen Black Bloons, 5 Regen White Bloons

5: 5 Rainbow Bloons

6: 1 MOAB

7: 5 Corrupted Ceramic Bloons

8: 4 MOABs

9: 1 S.O.D.I.U.M.

10: T.M.A. Mk. I (Boss version)

Strategy
Due to the rapid escalation of the bloon types, Ice Towers will be helpful, along with Boomerang Throwers. To deal with the MOABs, get a MOAB Mauler. Because fighting the T.M.A. Mk. I will take a while, your money production will be rather low, but you'll probably have a Super Monkey or two after a while. The Robo Monkey is more useful than the Sun God here; it's cheaper and money is limited.

Rewards
For completing this mission, you get 100 MM and you unlock the fight against the T.M.A. Mk II.
