Anything to help play through HL2 in gmod?

I just got HL2, so I loaded up the first map in gmod, I got to the crate part, and walked into the loading screen, then nothing. It said “loading” and nothing happened, yes I did wait and stuff, Any help would be appreciated.

Also I’m missing hunter model, zombine texture, etc. still. Help?

  1. loads next map, i recommend just playing the game by itself, play it in gmod later
  2. those models are from like ep.1 and ep.2, if you have them make sure to mount them

Thanks, I got ep2, but I’m saving for a computer, and all my steam purchases slapped me back down to 30 dollars.
