Hotline Miami is a depraved, deranged, disgusting, disturbing, and ultra-violent video game. It will make you vomit with glee. I couldn't find and gameplay footage online, so here is the 1st part of it, without the tutorial, 3 chapters. I had already played it a little bit and unlocked some masks and weapons beforehand. The game runs at 1200*768 pixels fullsceen, so I had to reduce the scale a teensy bit to make it fit in 720p.
