Bloons Tower Defense 5 - Daily Challenge 22 September 2012 (That Special Bunch)

That Special Bunch - Start at round 35 on Monkey lane hard with 0 cash. Use the provided agents to hold the bloons off till you get more powerful towers. 8 towers maximum.

Since you don't have any money in the beginning, agents are what you are depending on. Bloons Device is the most important early game as you won't have enough firepower to kill all the bloons in time until you have at least 2 Sun God. For the rest, you can pretty much learn all the agent placement in my video. Remember to set both the Tribal Turtle to aim last.
