I have got a question.

I preordered Crysis II via steam. I like the very cool functions of steam e.g. invite friends to gamerooms when they are not ingame. These functions were not implemented in the beta. Will they in the Final?

And a small second question. How to change my e-mail address? I only found the function to change my password.

Crysis 2 does not have steamworks integration, so no to your first question.

if it did have steamworks integrated, it would prolly be using **** VAC. but thats another discussion

LOL, you're not the only one who wants to know.
