In this mission you will work as a Gatekeeper of area 69. You will check every visitor's documents. That's it, no more spoilers.

For no particular reason here's how to initiate a slide: Press Crouch>W>Sprint>Aim in quick sequence. (Don't worry, it's not required!) And if you want to slide with minigun: Crouch>W>Sprint>Change Weapon>Aim

In this mission you will encounter:
Documents checking
Shooting range
A nightmare
Mass genocide
War crimes
A psycho with a fire extinguisher

That's all I can say without spoiling much!

This is the first time I've tried a DYOM Editor tool, and I can't believe I haven't found out about it earlier! I've also discovered the beauty of "Player Animation" and how it can seamlessly transition between animations!
