nope Simply head over to FileShack to download the Medal of Honor Multiplayer Open Beta Client ahead of Monday's beta. The maps Kunar Base and Shahikot Mountains will be available to play, "inspired by real-world locations" and offering the 'Sector Control' and 'Combat Mission' modes respectively.
The last phase of the beta ran through August 9 and improvements have definitely been made to the game since then. I played an updated build at PAX Prime about one month ago and it was a much more polished experience.
Anyone can participate in this open beta. Just download the client and wait patiently for Monday. You will need an EA account, though. The full game will be released on October 12 on the PC, PS3, and Xbox 360.
