 In level 1 ("Seppuku Station") is a TV playing footage of Michael  Fayes Singapore caning incident. After you get the gold key located  on the crates, youll notice a window of a room above which houses  an Uzi. If you stand along the ledge with this room to your left,  you can make out another window dead ahead. Make a running jump  towards that window and youll land on the ledge of that window.  Inside, youll see the video along with some weapons and a medkit.
