crossing NPCs from one game to another

[nekoheehee]

is it possible in any way to take an NPC like a combine and put them in another source game like CSS? or more ideally take a civilian zombie download made for GMOD and put it in HL2 for a single player game (so not DM.)?


also this is my first post, so i want to say hello and introduce myself. people call me nekoheehee (got it from my evil way of playing with people like a cat with its food during DnD games as the DM) and i'm a 3D and 2D animator for a ad agency in PA. i like designing games in my free time and hope to make a career out of it soon.
thanks for your time and i hope someone can help me out

I don't think you can do the first thing and you certainly can't do the second thing (without modding).

You might be able to make a plugin to add a COmbine npc to CSS, but I wouldn't count on it.
Half-Life 2 doesn't have lua support so you can't use anything from GMod. You can make a Half-Life 2 mod with lua support though.
