The Bloons TD 6 (BTD6) modding community is constantly innovating, and one popular concept revolves around giving players more control over their tower upgrades. While there isn’t one single mod universally titled “Upgrade Monkey Mod,” the idea often manifests in mods that allow for more flexible or powerful upgrade paths than the standard game offers.

This can take several forms, such as:
- Removing Crosspathing Restrictions: Mods like “Ultimate Crosspathing” allow you to get all five upgrades in every path simultaneously (creating “5-5-5” towers).
- Custom Upgrade Paths: Some mods introduce entirely new upgrade paths for existing towers or even create new “upgradeable” monkeys with unique branching options.
- “Choose Your Own Upgrades” Style Mods: Mods like “Ancient Monkey” or “Enhancement Monkey” provide a system where you spend upgrade points to select specific weapons and abilities for a tower, offering immense customization.
This guide will focus on the general concept of mods that enhance or alter the upgrade system, allowing you to make your towers feel truly unstoppable.
Important Note: Using mods in BTD6 is done through third-party software and carries potential risks. Ninja Kiwi may detect mod usage, which could lead to your account being flagged, preventing you from participating in online events like Races, Odysseys, and co-op with non-modded players. It is strongly recommended to use upgrade-altering mods on a separate account if you wish to continue playing online without risk on your main account. These mods are also only available for the PC version of BTD6. There are no reliable and safe methods for such mods on mobile devices.
