I have a few questions regarding this topic, I own BlazBlue CT on 360 was able to play people on the PC as well as 360 owners, is there anything like that on CS? I won a free PS3 CS game in a Tekken tourney and I am only able to fight PS3 users was just wondering if the 360 version of CS has PC players on it like how it was on BB CT? This is a pretty old topic but would like to hear a response.
