I need an anime to binge on, any help?

I don't watch much bloody anime, but Hellsing Ultimate seems to be a decent adaptation of the very good manga. Kuroshitsuji was a good series but apparently they may have neutered the darkness a bit

Neon Genesis Evangelion. - more Mecha, Post-apocalyptic, but if you haven't seen it, it's a must

+1 for Death Note

anidb.net -> search for tags like in the mentioned series. :)

Mhm! Enjoy the following: Kill La Kill, Sekirei,Vampire Knight, Freezing, My Bride is a Mermaid, Heaven's Lost Property, Harlock: Space Pirate, Deadman Wonderland, Blood+, Rosario + Vampire, Dance in the Vampire Bund, Blue Exorcist, Attack on Titan, (Psycho Pass you've already seen), Death Note and Knights of Sidonia.

People mentioned Ergo Proxy and Elfen lied, those should be perfect for you. I'll add in Corpse Princess and Berserk they are very dark and bloody and are some damn good series. I hear Gantz is extremely violent but I havnt seen it myself. Someone mentioned Mushi-Shi which is a dark anime but it has no major action/blood it's just heavily story-based and it's really good in that regard. Also honorable mention Highschool of the Dead for lots of fan service and blood.

If you like those with few episodes you could check out Shingeky No Bahamut and Noragami.Also there is Zankyou No Terror.

Hunter x Hunter 2011, Became my favorite anime after watching it, it took me 1 week to watch 133 episodes because i was so hooked, around the first few episodes it doesn't seem like it's dark and it kinda looks like the usual Shonen, but if you stick with it, you are gonna have lots of mixed emotions. Also Code Geass loved that one it has an amazing story, and if you try to guess the outcomes most of the times you are gonna be wrong(which is what i love about it, its unpredictable). And Tokyo ghoul, main character is kinda wimpy for most of the episodes of season 1, but he gets really badass somewhere around the end(plus season 2 came out a few days ago).
