I didnt pre-order MOH Limited Edition, but did buy it new on release day. My code came via email at 14.00UK. I dont think pre-ordering MOH was required to rec an early beta code. Everyone who registered the MOH 'online pass' should get a code.
how will i get the beta on the 27, how to get the code and when?
You only get the code if you got the limited edition of medal of honor,besides you only get the game 2 days early. Just be patient and wait until the 29th like everyone else who didn't pre order medal of honor.
