I remember seeing it on YouTube awhile back, but I can’t seem to find it. I believe the video is from the UK and is in a urban setting. I think it was for Military/LE training. One of the scenes is when they’re on the bus and the buss is driving around in circles. Also, they’re walking through an abandoned house/warehouse and they have random attacters coming out of certain rooms. Any of this ringing any bells? Thanks in advance.
