Plays inside your own copy of Garry's Mod, on your device, not in a browser tab. Opens github.com in a new tab.
How to play
Have your own copy of Garry's Mod installed: the mashup plays inside it.
Download it from its release page on GitHub (it runs on Windows).
Install it as its page says. What it asks for is just below, in the list's words.
Start the game the way its page says: some mashups come with a launcher of their own.
What it asks for
Garry’s Mod on the x86-64 branch, a controller, and the user’s own Xbox 360 Skate 3 dump are required. The creator recommends disabling Steam Input if the controller does not respond. Each player who skates installs the mod locally.
