In Heat

(Deprecated with the release of Overwatch 2, see Underwatch for a similar OW2-compatible mod)

A windows application to control sex toys based on the user's performance in Overwatch (On-fire Meter)

Here's a list of suported devices (only vibrating or linear toys will work for now):


  • This application is not a cheat nor does it inject any code into Overwatch, but Blizzard's End User Licence Agreement is vague, so I can't guarantee you won't be banned. Use In Heat at your own risk.
  • Remember to always play safe, sane and consensual. Please, do not drag unsuspecting players into your play.

Making It Run

Video Tutorial:

  • Dowload and install Intiface Desktop.
  • Download a release(.zip file) of In Heat and extract it to a folder.
  • Open Intiface Desktop and start the server, the computer icon on the top right should turn green.
  • Turn on (Bluetooth) or connect (USB) your devices.
  • Open the InHeat executable inside the folder and click connect. Intiface's phone icon should turn green and a list of connected devices should appear.
  • Open the game and test it. You can easily do so by creating a game with bots (Play > Game Browser > Create > Add IA).

Bugs And Observations

  • The game/image must be open in your main screen (in case you have more than one monitor).
  • The game must be running in borderless mode for the overlay to work.
  • Only tested on 1920x1080 screen/game resolution, let me know if it works on a different resolution.
  • Only tested on the game's default color scheme, if you want to use a colorblind color scheme please let me know.
  • In Heat only works with devices that vibrate or stroke.
  • If you want to use XInput devices (gamepads) as vibrators you'll have to follow this workaround to disable the game's control over the gamepads.

How It Works

Controling Devices

In Heat uses the Buttplug library. Buttplug is an open-source standards and software project for controlling intimate hardware, including sex toys, fucking machines, and more.

Tracking The On-fire Meter

In Heat uses Emgu CV, a C# image processing library, to locate the brightest cyan spot on the bar area, and calculate the distance from the capture box origin;
