What powers Rust?

I don’t play it but I looked it up and it looks really fun. What I would like too know is: Does Rust run on the Source Engine?

Yes, the Unity splash screen is just a ploy, and everyone complaining about Unity errors when playing the game is in on it as well.

Haven’t seen it mate. I don’t play it as I have no key, second I haven’t seen a video in which Unity appears.

Could’ve at least read the About Rust section on the main page of the wiki.

Unity
(in case you didn’t get it the 2 first time from the guy above me :P)
