Basically you drop OL 2.2 into the complete mod then edit a bunch of files. I don't remember how to do it exactly anymore, but I can send you a copy if you really want. I do seem to remember needing to edit a bunch of files to point to the right textures, and little things like that. I still have an energy drink in there or something that shows up one color in inventory but a different color in 3D and I never bothered to fix it. Also the weather changes are rather abrupt. I don't know what that's about. That's all I really remember. But it plays fine all the way through to the bitter end! The main reason I did it is because OL had my favorite gameplay and SC2009 had the best night effects.
