Hitman 2: Silent Assassin & Collector - Mission 04 Tubeway Torpedo

The main goal is to collect all weapons in Hitman 2 with SA style.
Weapon: DEagle, Combat Knife
The hardest part in this mission is to avoid all contacts with guards on the
ground. After 47 changes his clothes and gets into the military facility, things
would become much easier.
Notes:
The first guard's movement can be triggered by footsteps.
