I have found a way to get a free Metal Gear Online BETA code for USA every time (got about 5 from this with 0% failure rate).
As you guys might have heard the BETA is having tremendous issues as is, and its pretty unfair UK and Japan all get the BETA for free while US has to go out and preorder the game to enter the BETA.
Recall that many people had a error of getting 9 letter codes versus 12 letter codes from the Metal Gear Saga Vol. 2. Konami said to fix this issue you would have to email them to get it fixed, will since this was a error on their part they really have no way to check to see if the code you send them is legit or not.
How to get the free key:
Its fairly easy process first go here: http://www.konami-data.com/support/
Fill out the information it asks for, this is what I chose from the drop down menus for those who hate to read:
In the Question Detail: area is where your going to write up your message, this is where you have to sound like an innocent and frustrated newb
Tell them that you got the Metal Gear Saga Vol. 2 DVD from a preorder at Gamestop/EBGames and you found that the code was only 9 digits long instead of 12, and when trying to enter the code, it would be rejected. Also let them know you live in USA, and ask them to please help.
This is what I sent in, not recommended you use the same message or your request might get bounced back:
Be sure you include the fake BETA key, it can be anything 9 characters long, just no symbols and all caps. Besure to use a combination of numbers/letters.
Send the form and that's it, I got a reply back from them in about 2 days with the new BETA key.
And there you have it, a new brand, free, USA MGO BETA key!
Note: Konami is now asking a scanned form for this method, here it is, photoshop and add in the fake characters:
