To my knowledge, you never receive info on damaged internals on a computer. I recall one memorable session where a comp ejected with maybe one part yellow, and I couldn't figure out why, till the end of game and I looked at his ToS, and just about all his systems were medium or heavily damaged... Gotta love mesons
To do a net game, you see that thing on the battlefield that says Network Game? (You need v1.4) You also need to contact someone with ICQ or some other IM program. You need their IP, if they're hosting, or you give them your IP, if they're hosting. Then just fill in the info, and its pretty self-descriptive from there. If it isn't, the person yer chatting with on the IM prog will help you
