1. Start the game by placing Quincy on the rock at the bottom center of the map. Then, place a Dart Monkey on the upper rock.

3. Place a Heli Pilot on the rocky area to the right and quickly upgrade it to 2-0-0.
4. Upgrade the Sniper Monkey to 1-1-0.
5. Upgrade the Heli Pilot along Path 1 to 3-0-0 with Razor Rotors.
6. To give your Heli Pilot camo detection, place a Monkey Village nearby and upgrade it to 0-2-0.
7. Support your Heli Pilot with an Alchemist and upgrade it to 3-0-0.
8. Upgrade the Monkey Village along Path 1 to 2-2-0 for Jungle Drums to boost attack speed.
9. Use Quincy’s ability to pop the MOAB that arrives on Round 40.
10. Upgrade the Sniper Monkey to 2-2-0.
11. Upgrade the Alchemist to 4-2-0.
12. Upgrade the Sniper Monkey further to 3-2-0.
13. Upgrade the Heli Pilot to 3-0-2, and start saving money. By Round 57, once you have enough, upgrade it to 4-0-2 with Apache Dartship.
14. Place a Wizard Monkey on the upper-middle rock where it can cover the lower path, and upgrade it to 0-0-4.
15. Support the Wizard Monkey with an Alchemist upgraded to 3-0-0.

19. Place two Boomerang Monkeys above and below the Glue Gunner to cover both paths, and upgrade both to 2-0-4.
20. Use Quincy’s abilities to help survive Round 95.
21. On Round 96, if you have the funds, upgrade the Heli Pilot to 5-0-2 with Apache Prime.
22. Place a Monkey Sub and upgrade it to 0-4-0 so the missile will be ready to fire at the ZOMG on Round 100.
23. Round 99 is tough! Use any remaining cash to power up the towers on the upper-middle rock, and time Quincy’s abilities correctly to beat the round.
24. Use the Monkey Sub’s missile and Quincy’s ability to take down the ZOMG in Round 100.

Victory is yours!
