Can someone help me find a mod I used to have?

Here’s the story.

A long time ago, in a galaxy far far away, I had a computer. That computer sucked. On that computer. I had a mod. I have a new computer. I forget that mod.

Yes that was a terrible story and included very short sentences. Anyway as it attempts to say, I used to have a mod for Garry’s Mod. In this mod I could pick a player model, like Breen, and combine wouldn’t attack me and the resistance would. If I chose stuff like a rebel, rebels wouldn’t attack me and combine would etc. Anyone know of any mods like that?

Something like this?

That’s exactly it, thanks a bunch.
