i honestly would have been surprised if it didnt play like bad company 2. dice was hired on to do the multiplayer for medal of honor and they used a lot of the same engines(if not all the same) for the multiplayer.
the multiplayer plays pretty much the same as the beta. a lot of the maps i played were small-medium sized maps, which i liked because there was fast paced action.
ive heard the single player is fantastic. i didnt play it yet, i only got about an hour and a half of game time in yesterday before i went to bed.... i hate working mon-fri 40 hours a week + overtime if i have to
