Having given it some thought, and also having acquired the Euro Forces pack, I think I'll be skipping over this one.
I was hoping, in EF, that the new weapons would be available in normal maps, or maybe as unlocks or something. It's just like a tiny extension, though, and the one map I've actually had chance to play (Operation Smoke Screen) I really didn't like -- too much damn airpower, too little anyone can do about it. So a mod with more planes, so more chance for being raped from the air, really isn't appealing.
That said, I've wondered, on-and-off, about getting Special Forces. Is it worth it?
