[HELP] GMOD 13 SVN

Hi everyone,
I downloaded the SVN version of GMOD BETA 13 and I placed second in sourcemod folder garrysmodbeta, but the game does not appear in the list of games steam.
I own gmod 12.
A friend asked me my key gmod 13 1 month ago, I gave him because I played not gmod 13. Now, I want to play, that’s why I took the SVN version.

I believe the SVN just provides the most up-to-date updates for owners of the Garrysmod 13 beta.

Correct me if I’m wrong. :stuck_out_tongue:

You still gotta get the key silly.
