Where the hell is the shotgun, i cant find it anywhere. And how the hell do i beat the boss on the plane i hit him with the crates about 4 times after i shot loads of times with the flame rounds but he still wont go down. Plz help me.

You can get the shotgun when you are Chris. But the Tyrant only needs a few flame rounds and all the bow rounds and he drops easily.

Use the BOW Gas Rounds for the Tyrant, makes it so much easier, you need all bow and flame rounds etc for later on in the game when it gets tougher, you find the BOW Gas rounds at the other side of the metal detector room where you see Steve in the computer room, you have to head back that way when you are getting the Piano roll, where you move the crate out the way and then pick them up. Easy...

If only there were more BOW gas rounds, i loved them, but only 3! They were amazing.
