Is it posible to mount other source games?

I’m looking to mount Left 4 Dead (1/2) and alien swarm, Is this possible?

You can sue Gmount2 to mount L4D and L4D2

alien swarm: no idea

Holy crap, I want the AS weapons!

I think you can do without sueing it, I mean it IS a great addon

I think he meant use.

Alien Swarm doesn’t work 100% at the moment as it uses VTF format 7.5, whereas currently GMod (even with Mount2) only supports 7.4

Unless aVoN secretly updated it.

I kinda knew that, was just trying to point out said mistake in a funny way.

I thought Gmount2 was broken?
