Bollocks !!!!!

Maybe it's a good game when you play it on line , but first person campaign is total bollocks !!!
At first it is bearable to play it , but later on it does become annoying ....
You go and shoot some bastards, you kill about 40-50 of them and than you enter for example in some cave and when you come back everybody is alive again.In the cave(it's some guy's hideout) is even worse, there you go and kill some idiots,pass three or four rooms and when you come back there are some more idiots,you kill them and ....it can go for ever you now...
I hate this absolutely ridiculous game!!!!
