Free Steam keys on that link.
Disclaimer: You need a valid Steam account with the paid Garry's Mod on it to get a Garry's mod 13 beta key.
How is this piracy @gravzy, creator decides to give away the keys for free.
It's really slow?
Got a key
First reaction: "Free Steam keys? Free GM?
"
What I saw: "You don't appear to own GM"
After that: "WTF I HAVE BEEN THIKNKING OF"
I already had one months and months ago, still pretty cool that garry gave them away to everyone now
This site still has limited amounts and tbh it sucked months ago. No idea what changed since then, probably still a miserably failure of a copypasted game.
anyone want to get me it :3?
