There is no killbox, I cannot shoot at your legs, there is that wireframe large 128x128x prop in the way of your feet.
The video clearly shows you being shot in my line of fire right in the center
You can clearly get past the door. There is no evidence of you getting stuck/not being able to get through, I tested it and I managed to get through fine.
You just needed to walk left. In the video you were walking to the right into the door.
Here's a screenshot I took, proving that you can walk through:
Zachery Wraith was moaning at me in-game claiming that it was a killbox, I told him to make an F1 as there were members of staff on at the time, Jayo and SilentCall. He refused to make an F1 ( I wonder why ) and made this thread.
I wanted him to make an F1 so they could check it out and see for themselves. I took a screenshot proving that both SilentCall and Jayo were there.
