Forum:Modding Question, woo

FIRST OF ALL, YEAH MAYBE THIS SHOULDA BEEN IN THE HELP DESK.

BUT I 'PUBLISHED' IT THERE AND IT NEVER SHOWED UP.

SO IM TRYING HERE.

Anyways, I wanted to ask; does modding disable Steam Achievements?

I've gotten a little intesrested in modding, but just to be safe, I would like to know if modding will cost me my achievements. I'm a completionist. Can't live without my pointless achievements.
