Can i add Garry's Mod to Source SDK without any of the Orange Box games?

Is that possible?

No.

Ok

This is a good thread.

Yes.

EP2 Will do.

Don’t mind it’s being broken at the moment.

I suggest reading the thread title. He does not own any game included with the orange box.

No.

Oops, my bad.

Yes, you’d have to write the CFG manually and it would still appear under the episode one engine.

It’s possible but not worth it. Garry’s Mod alone mounts other games plus any addons you have, the load times for maps would be immense.

But it is possible to create a configuration for Souce SDK Base - Orange Box.

Garrysmod != Source SDK
