Hitman Blood Money - PRO/SA/All Guns speedrun in

The goal of this run was to complete the game on Pro while getting the Silent Assassin rating in every mission, and to collect each gun that to the hideout. The nailer is collected despite it not appearing in the hideout as it does show up in the weapon select menu. The real WWI pistol doesn't appear anywhere so it's not collected. The custom 1911 doesn't appear anywhere either, but I end up getting it anyway.
When collecting large weapons I often use the detonator glitch, which makes the NPCs unable to see the weapon I'm carrying. -- Watch live at / thekotti
