Yep, just install Rising Storm/Red Orchestra multiplayer.
Last week we also did 2 vs 2 + AI bots. It was quite good actually. Loved the last map with the factory buildings. Great scenery and good places to hide :). I also liked the tank battle map. Sort of WoT but then from 1st person perspective!
There is a sort of mini-campaign mode where you have to progress through a number of "levels". Win/loose results determine the army strength of the next level. Wouldn't it be great to have this for RoF or BoS?
