10 Things You Must Know About BTD6 Mods

The world of Bloons TD 6 (BTD6) modding offers exciting ways to customize and enhance your gameplay experience on PC. From new towers and heroes to unique game modes and quality-of-life improvements, mods can add a fresh layer of fun. However, before diving in, here are 10 crucial things you must know about BTD6 mods:

1. PC Only (Generally): As of April 2025, the robust modding scene for BTD6 is primarily focused on the PC version of the game (available on platforms like Steam and Epic Games Store). Modding on mobile devices (Android and iOS) is significantly more complex, often requires rooting/jailbreaking, and carries substantial risks. Be extremely cautious of any claims offering easy BTD6 mods for mobile.
2. MelonLoader is Your Friend (Usually): The vast majority of BTD6 mods on PC rely on a mod loader called MelonLoader. This is a third-party tool that allows mods to be injected into the game. You’ll typically need to install MelonLoader first before you can use most mods.
3. BTD6 Mod Helper is Often a Dependency: Many modern and more complex BTD6 mods require another foundational mod called BTD6 Mod Helper. This acts as an API (Application Programming Interface) that simplifies common modding tasks for developers. If a mod description mentions BTD6 Mod Helper, you’ll need to install it as well.
4. Installation is (Usually) Straightforward: Once MelonLoader and BTD6 Mod Helper (if needed) are set up, installing most mods involves downloading the mod file (usually a .dll file) and placing it in the Mods folder within your BTD6 game directory. This folder is typically created by MelonLoader after its first run.
5. Use Mods at Your Own Risk: Modding is not officially supported by Ninja Kiwi and can sometimes lead to unexpected game behavior, crashes, or even save file corruption (though this is less common with well-maintained mods). Always download mods from reputable sources.
6. Offline Single-Player is Highly Recommended: Using mods, especially those that provide unfair advantages (like infinite money or overpowered towers), in online modes like Races, Odysseys, and public co-op can lead to your account being flagged or potentially banned by Ninja Kiwi. Stick to offline, single-player mode when using mods. Some players even use separate accounts for modded gameplay to avoid any risk to their main account.
7. Mod Compatibility Can Be an Issue: BTD6 receives regular updates, and these updates can sometimes break compatibility with existing mods. Mod developers usually need to update their mods to work with newer game versions. Always check if a mod is compatible with your current BTD6 version before installing.
8. Trusted Sources are Crucial: Download mods only from reputable sources like Nexus Mods ([nexusmods.com/bloonstd6]), well-known BTD6 modding communities (often found on Discord), or the mod developer’s official GitHub repository. Avoid downloading .exe files claiming to be mods, as these can be malicious.
9. Read Mod Descriptions Carefully: Before installing a mod, always read its description thoroughly. Understand what the mod does, if it has any dependencies (like BTD6 Mod Helper or other mods), and if there are any specific installation instructions or known issues.
10. The Modding Community is Active and Helpful: The BTD6 modding community is generally welcoming and willing to help. If you encounter issues with a specific mod, try reaching out to the mod developer (if they have a Discord server or contact information) or asking for help in BTD6 modding communities.

By keeping these ten things in mind, you can safely and enjoyably explore the exciting world of BTD6 mods on PC and discover new ways to play your favorite tower defense game!
