Multi User for Bloons TD 6
Introduction
Multi User is a mod for Bloons TD 6 that allows you to run multiple copies of Bloons TD6 at once.
Download
You can find the download for the mod in the Releases Section on GitHub.
Simply extract the DLL to your Mods directory.
Warning
⚠️ RISK OF DATA LOSS.
Before using this mod, consider creating a backup of your save data contained in:
Steam/userdata/<user-id>/960090
Usage
In order to use an alternative profile:
- Create a game shortcut.
- Add desired flags (see below).
- Launch game.

In this example, adding --profile Sewer56 --save Sewer56 will make the game use an alternative account associated with the name Sewer56. When you boot into the game you'll be prompted to log-in. When you use the same shortcut in the future, you will be automatically logged into that account with its own separate save file.
List of Available Flags
--profile ProfileName: Specifies an alternative account to use.
--save SaveName: Specifies an alternative save file to use.
It is recommended to specify both --profile and --save; unless your intention is to share the same save file between multiple accounts (co-op with self).
Note: This mod will likely get you hacker pooled and (by design) cannot be used to circumvent the hacker pool.
