I haven't even tried the multiplayer but the single player portion of Medal of Honor is seriously fuckin broken. I am only into the second "chapter" which seems to be a bit better but....holy shit the first part sucked ass.  
 
Enemies seriously disappear right in front of you. Animations are FUCKIN HORRIBLE!!! Like BUDGET SHOOTER level type of stuff.  
 
I'm going to try the multi half some time after I struggle through the single half.  
 
God I hope it gets better.
