Half life 2 mod

[Storfigge]

I've so far created one Amnesia CS and is currently working on my second one which is almost done. Before I started modding Amnesia I had no clue about programming, I've learned what I can here on this forum and the wiki page. I'm really enjoying making custom stories. Now I would like to know if any of you guys here on the forum has done any HL2 mods? Is it much more advanced than Amnesia or is i like "If you can do Amnesia mods you can do Half life mods". I would like to try making something with a bit of action.
I hope it's ok to ask about this here since this is an Amnesia forum and not a HL forum .
