Great shotgun montage by TheXBLJMOR, but what I wanted to draw your attention to was his quick reload of the weapon. When reloading, once your ammo count has increased change weapon and back again and your weapon will be reloaded. Here’s a forum thread on the technique:
- Reload
- Wait until your ammo counter says the gun is reloaded (the animation won’t be finished yet)
- Interrupt the reload (ie swapping out weapons, etc)
- Kill something
- Run out of ammo in magazine
- Repeat
