I have an official promo disc of Uncharted 2 : Among Thieves for the PS3.
This promo is the full game, and is exactly the same game you would buy in the shops, this is an official sony promo.
No box or manual included, the game comes in a jewel case.
Having completed the game (on hard, i might add)!, it's just been gathering dust.
Believe what you read, this is a modern day classic.
