MGS2:where do you go.

[Rocky]

having got mgs2 this weekend i am now stuck at the bit where you have found E.E and have to go 2 the computer room.
I went back past the bit where you just fought Vamp.
I cant get to strut L (which is where you have to go) because i don`t know where it is and E.E keeps on running out of oxygen.
Can anyone tell me how 2 get to strut L?

You just have to retrace your steps till you arrive back into the collaspe strut area.Then from there you can pretty much find your way back.Anyways if emma starts running outta air surface in one of the air pockets there labeled whitish blue on your radar
