hey mate... try typing this into console ( where you insert the map name put in the name of the level you want to play - without the brackets)
I think the name of your map is: MadisonSquare
map [map name here]
for Semper Fi or Die the command would be:
map MadisonSquare
where you find level names (Win 7):
C:\Program Files (x86)\Steam\steamapps\common\crysis 2\gamecrysis2\Levels
hope it helped... if you don't have this game off stream please go to Crysis 2\gamecrysis2\levels
