Splat, I can honestly say that I think you will enjoy Red Orchestra. The gameplay and pace of the fights is very similar to COD4. There is also the added bonus of "realism" to the game, you need to account for bullet drop and you need to lead you targets etc. Try it out, for the price it's at you can't go wrong. Since I left COD4, this game is by far the closest approximation in terms of gameplay, tactics and pace
