achievement"Killroy was here" should be changed !!!
I've done it by going to the left the door going to the objective several times,but the game refuses to give me credit,since the game demands you follow one path only,period.What do anybody else think of the subject.On the internet,one site shows you how to accomplish the mission,but the jerkused a cheat file to excellerate his character to run pass everybody to get to the location,which I just refuse to do!!!!
