Some ppl on my friends list are playing it how'd they get it though?How can I get the medal of honor beta for ps3?
You have to pre-order Medal of honor to get a code..

then you take that code to the medal of honor website ( http://www.medalofhonor.com/beta ) log in with an EA games account, put in that code and it will generate the beta key for you. which is also where you download the beta



im pretty sure it ends on the 19th July so better get in quick

I play it on PC but its the same deal
