hmmm. I might have misunderstood you, but i use the regular latest source code build(well its an older version now). I'll find you a link.
It plays exactly like normal CTP2 except at the momment the MP aspect hasn't been fixed(but its being worked on as we speak).
If i want to do a multiplayer game i stick with the origonal CTP2+activision patch+fav Mod(usually SAP or Cradle, but i also play others), but i haven't done this for a long time.
