Well, there is Black Lagoon that I mentioned to you before. There are 2 seasons of it, which lasts a pretty long time. The is graphic violence and Swearing (a lot of swearing) This series is very action heavy, and I really enjoyed it.
Then there's Elfen Lied. This anime has a very deep story and is very sad, rather depressing. It has very heavy graphic violence and has scenes with nudity (although not really in the same line as fansevice) It is rather light on language though. It is a very great anime in my opinion, although if you're sensitive to violence, this might not be good for you. The entire series doesn't revlove around the violence though, it has a great story.
I'll link you to some reviews as well if you want. And trailers too.
