Played a game two weeks ago. Hit someone from inside a room out of the doorway, and saw two more guys behind him in the distance. The first guy walked right in front of my line of fire, so I tried to shoot around him. He then proceeded to have a go at me but I apologised anyway. Soon afterwards I realised my attack was a failure so I decided to leave the room via the back door. A minute later the marshalls announced "Weapons down! Weapons down!" through the PA. Turns out the guy I first shot came back with a solid-state grenade and attempted to throw it into the room, as he thought I was still there (I presume). He threw it at the glass door instead and shattered it everywhere.
So remember kids, don't stay in the same area for too long or you'll get impaled by shards of glass.
(It was actually safety glass so it shattered into billions of harmless pieces)
