Here are trailers for two 2008 Japanese films from Tokyo Shock that I watched recently. They’re outrageously violent. The Machine Girl was especially creative- it had a bra that had drill bits. In one scene a woman blows a hole through a guy’s stomach, then puts the gun through the hole to shoot someone else. A character shoots nails into a guys face.
I’m not going to tell you these are great films but they are entertaining if you can handle all of the bloodshed.
