I feel like an idiot asking since similar quesitons continue to be answered, but:
1. I know you need both Arma II and OA. If I buy Combined Operations on Steam for $30, does that handle everything I need besides the mod?
2. If I get Combined Operations on Steam, is there a step by step guide to installing the mod (which is presumably just a matter of copying over files)? I was looking around the thread and OP but maybe I'm blind and missed it.
3. Neither game is VAC protected, correct? So modding and installing this mod will not cause problems with VAC or other (normal ARMA II) anti-cheat systems?
4. If I want to see if my system can run it, the Arma II free version (not the demo) is the one to download on Steam, correct? Or should I get the demo since it's smaller?
