Is there any substitute for HL: episode 2, CS:S and the like?

I’ve never really gotten into Gmod because most things to do on it require Half Life episode 2 and Counter Strike Source. Is there any way to acquire the resources from those games just to use in Gmod, or do I need to just suck it up and buy those two games?

Buy the games. There are content packs avaliable – which links cannot be posted to due to the Facepunch rules, but they’re almost always incomplete or buggy. Buying the games is the best option for mounting the content.

Also, EP2 is not needed nearly as much as CS:S, so you could get by with just Counter-Strike.

I see, thank you. I suppose the games will be dirt cheap next time there’s a sale.

Garry should get them to be put in a bundle on the storefront with Gmod, they seem basically required for most things.
