I have the same issue. I read somewhere that we were supposed to buy it like the other default classes like when you would earn unlock points for leveling up. I hope this is not the case because i would really like to see how the custom class mechanics work. Hope this helps!How do you unlock the custom class in crysis 2 demo for the 360?
are you sure, you only have one custom class, and you can change it through the customize equipment

then you unlcok weapons and attachments, then you select them to stay for that class



if u still have an issue, then its because this is a beta download, and there are issues
