Well got the Ratslayer , la longue carbine , the mysterious magnum , mercy , bozar , smitty's special and Sleeyptyme.
Inorder to get La longue carbine I simply shot Sterling in the head with the Ratslayer while nobody was looking.
Mercy was very loving difficult to get. I mean I had to set it to "Very Easy" just to beat all the crapload of deathclaws because I was playing on hardcore mode - and I still lost tons of health and Lily.
