I know I’m not supposed to write it down here, but it’s just too funny to resist. Mods can move it if they want. Well, here it goes. I was fixing the ramp in White Chapel, and I could not and neither the other guy can mount it. Here’s what happened:

… Wtf
The last one you can’t see well, because I screenshotted it just when he went out.
It happen to some one i saw but not on an MG. He was actualy moving. The funny thing is you can’t aim the head 
But when it happen, the guy is so big that you can’t really hide ahaha.
Regular bug indeed, people moving in this position just used an mg and left it. One of the last I saw one he took an emp charge on chapel, rushed the obj, I wasted all my magazine on him until I stabbed him when he was trying to deliver…
I saw this twice yesterday lol. It would be fun playing a match where everyone looks like spaghetti man. I wonder if this changes the players hitbox…
Headshots are definitely possible. This is a very old bug as clown stated and if you aim for around the upper torso, you’ll hear that nice clank sound we all love to hear on a headshot.
