Welcome to the second big patch to Medal of Honor: Allied Assault. You'll listen to great music.
One thing which entertained me a lot was that the "difficult" level was really difficult, and it took me a lot of hours to finish the game in that level. It is almost impossible to successfully accomplish a mission without getting killed, so if you weren't used to use the quick-save and quick-load buttons --as it was in my case-- you definitely will have to reserve a finger for them...
...except that you really want to spend several hours trying to learn the enemies' behaviour pattern and the ideal path across the battlefield. Instead, you could read Gamespot's review of the game and give up your intentions.
The music is still good, and the sound effects remain impressive. But if you upgraded your graphic card thinking of the launching of this game, you'll get very disappointed, for the graphics are still as in the original game of the series.
