Hitman 2: Silent Assassin & Collector - Mission 07 Hidden Valley

The main goal is to collect all weapons in Hitman 2 with SA style.
Weapon: Crossbow
This mission is truly a pain in the ass. I mean it.
There are two bugs in this mission:
1. The trucks would sometimes run over the ninja at the checkpoint,
causing an alert. (That means you need some luck to get all zero.)
2. The trucks would sometimes come to a halt and never move for
the remainder of the mission.
In this video, I faced the second bug I mentioned above. I was waiting
for the trucks to take me to the exit from 09:50 to 11:40, but they just
didn't make a move. So I had to run through the tunnel myself.
Notes:
The key to whether the snipers acquire 47 as a target or not is "timing".
The snipers would sometimes check their rifle scope and not look outside of
the windows. The timing is programmed, so 47 could infiltrate to the base
without disguise if he knows the perfect timing to sprint.

Thanks! I thought no one would be interested in these videos now :P
