I think the game is mostly dead but we'll see what happens after the sale.
Red Orchestra 2 and Rising Storm are the same game. The difference is Rising Storm let's you pick your class on japanese levels. If you only get Red Orchestra 2, you're forced to be a rifleman in japan levels.
I wouldn't bother with RO2 any more but rising storm or whatever it is can be amazing if you find a full server. The base game is botched, buggy, and still divided between two installs/exes. --- There is a glory in humiliation. A throne to be claimed; a crown to wear! http://i.imgur.com/OhZgm.jpg
