A downloadable game for Windows, macOS, and Linux

Ultra Dance Murder Legacy

is a challenging twin stick arcade shooter with a fantastic heart pounding 80's styled synthwave soundtrack by Three Chain Links, glitch art, dance inspired combat, and local multiplayer gameplay that either builds or destroys friendships. Don't have friends? That's fine, AI will always be your friend. Set in a futuristic antivirus immune system where you are tasked to quarantine and eliminate all threats to the central operating system, even if it takes one restart after another. Play either with or without an XBOX360 gamepad.

If you like the soundtrack support James by listening to his music on bandcamp!

And if you enjoyed playing the game please vote for the remastered version on greenlight!


Late December 2014 Ultra Dance Murder had a very small conceptual build which was shown at Colorado Clutch Con, a gaming convention, and got some positive feedback and attention there. Therefore, the development continued!

Greenlight campaign

On August 28th 2015 StevenHarmonGames put Ultra Dance Murder on Greenlight in order to have a chance at getting the game published on Steam. It didn't get enough votes yet, but nevertheless you can still vote now for the new rebuilt game!


The game's greenlight was a learning experience in marketing and is currently in a sort of limbo. The game was put on hold for some time. However, January of 2016 Steven decided to scrap all progress made on udm up to that point and remake the game better than originally envisioned. The remake of the game is now expected to release by Spring of 2017. However the original feature complete finished version of the old UDM is free to play here.

What if the game doesn't run?
  • If you're playing on a MAC you may need to press the control key, click the app icon, and choose open from the shortcut menu.
  • If you're playing on a PC you just need to run it either as an admin or approve it if the dialog comes up
  • If you're playing on a Linux, you should be fine. Linux is cool that way.
Best practices
  • If you plan on playing with a gamepad, be sure to plug it into your PC before you launch the application, because the game auto detects how many gamepads you have at the start (This is kept track of to give you the correct controls in the controls menu, and configure the game's various modes to either play with AI or not. If you have 2 or more controllers you can play locally with a friend!)
