I purchased ME2 recently, and the code it came with had expired. Today I spoke with EA Support on the phone, and they told me you can download it for free from http://social.bioware.com/page/me2-dlc. The Cerberus Network is listed there, it says it is free, and there are links for PC, Xbox and Playstation. The only one that does not work is the Playstation one (it takes you to the Playstation Network and then says "Page not Found"). The EA Agent I spoke to told me to contact Bioware support, but I cannot find an email for them. Can anybody help?
