In just 2 days, Konami and Sony will allow gamers who have obtained a beta key to download the MGO client. According to the PlayStation Blog:
If you have attained a MGO Beta UPVC, then Thursday, April 17th, this week, the download of the MGO Beta client will be available to you through the PlayStation Store on your PS3 (but please bear in mind, gameplay does not start until April 21st , and then will run until May 5th) – again, please do not try to redeem your UPVC before April 17th, you will just get an error message. You need to carefully follow the instructions provided on the MGO Beta UPVC insert in order to get at the download of the MGO Beta client through the PlayStation Store on your PS3. It is also important to note that your UPVC for the MGO Beta is good for only one PS3/PSN/PlayStation Store account, so you should absolutely NOT share your UPVC with anyone (unless you plan to forfeit your MGO Beta to whoever you give the UPVC to). There will not be any additional issue/reissue, replacement, etc of these codes – so again, we stress, please DO NOT share your UPVC for the MGO Beta with anyone!
MGS4 is one of the most highly anticipated PlayStation 3 titles to date. You can obtain a beta key by reserving the game at a GameStop or Best Buy location. You can read the rest of the MGS4 post at the PlayStation Blog HERE.
