Doom
 

Hello,

There is a game called DOOM (released 2016 on steam), it has a free demo on steam, DOOM Demo.

How can I run DOOM Demo without steam?
What can be done to make it work without steam?


(Again, I am talking about free DOOM Demo, not DOOM full version)

Your question is outside the scope of this forum. (See forum rule #1 about cracking demos and digital downloads. Steam has its own backup features so your purchased games won't be damaged as no physical media is involved but this is a free demo anyway. I do understand, though, that you don't want to "infect" your PC with Steam.)
