Re: Multi kills with Tactical and SMGs

@aaomorph3us& @Kompura:

- Equip the 12M with the extended mag.
- Find a busy flag (C on Exposure, C2 on Stranded.
- Sprint up to a doorway and slide across it.
- Face the doorway as you slide.
- Shoot. Just hold the button down.
- Profit.

This will also work for the headshot task as you get random headshots with shotguns - if the pellet that kills is a headshot, you get a headshot kill.
