So I'm on the last step of the last T4 mission with Mamba and am at the stage of "Find Captain Bosscrelli" to get the silver keys I have spent 2 days looking all over this prison (where I can go with out being shot) and can't find him anywhere.

Can anyone who has finished it, and remembers where he is supposed to be give me a hand?
getting stuck on this after 2 months is a bit of a bummer :)

Thanks in advance
