Boarding Pass

This is the first mission of phase 5. It is not too difficult and one of the last ones that you don't sweat it out.
You can take out most of the bad guys using stealth, which I always recommend (it should be a piece of cake for you now).
In the next to the last stage you will go head to head with your third boss - Stingray.
To me he was the easiest to beat (my first time here in easy mode I won the first time with around 75% of my health intact.
Once you get through Stingray, you unlock the security system and have 1:30 to get to the elevator.
But wait, you must also defeat all the bad guys along the way.
Use tonfas if you have to but try to keep at least a total of 4 in your inventory (you will need them soon).
On this mission you can add the following items to your inventory:
Health - 10
Ammunition - 1
Walkie Talkie - 1
