[HSA] Collection of glitches/easter eggs/tricks for Hitman 2

I couldn't see any post about "Hitman 2 Silent Assassin" Collection of glitches/easter eggs/tricks, so I made myself even though it's similarities with HCA.

I am starting with an unknown cool glitch that I have found couple of months ago. 

Hidden Valley Truck Glitch:

Triggering the truck glitch allows you to become invisible to ninjas. Cool trick to use in challenge runs like Sa/SO/AZ/Pro.
