I've bought Borderlands and I've been playing it on my own. I'm starting to get interested in playing co-op online, but never done it before so not sure how I go about it.
Do I need to do anything else other than the game & an Internet connection?
Do I just click on the Xbox live link in the game load screen to take me to the correct online location/screen etc?
Do I need to buy an Xbox live card to be able to go online?
A real newbie question but I've never played online, not sure how it works, and not sure if I'll prefer it to the single player I'm going through now. I don't want to pay loads of additional cash for Xbox live access and then not use it.
