Begin your Lost Crevasse – Primary Only (Easy) strategy by placing Quincy at the start of the map. You can optionally use his abilities to speed up rounds, but this guide works without any Monkey Knowledge or hero abilities.
Place a Boomerang Monkey and upgrade along Path 1 to 3-0-2, then a Dart Monkey along Path 3 to 0-2-4, creating a strong primary defense early in the game.
Enhance your Boomerang Monkey further with the M.O.A.R. Glaives upgrade, reaching 4-0-2 for powerful multi-target attacks. Place a second Dart Monkey and upgrade it to 4-0-2, balancing your coverage and ensuring no bloon escapes.
Prepare for Round 40 by placing a Bomb Shooter and upgrading it to 0-4-2, allowing you to easily destroy incoming MOABs. You can use its ability at the right moment for maximum effect.
With this setup, your towers are optimized for Primary Only mode on Lost Crevasse (Easy). Focus on timing your upgrades and abilities, and victory will be yours!
