Present Codes consist of a word that is posted on specific adverts, websites, and magazines. Finding a code word and entering it on Resident Evil.net will reward members with useful items that will be sent to Resident Evil: Revelations, aiding them in gameplay.
Codes expire within 48 hours, rendering them useless, so it is best to use them as quickly as possible.
If 10 codes, regardless if it's valid or expired, are inputted within a certain time frame, the site will recognize it as suspicious activity and lock the user out to temporarily prevent them from using any more codes. Once the time limit for the ban has been lifted, the user is able to resume using the service.
