Fatale is a great lovecraftian, crime, noir book from Brubaker. You may like that.
David Hines work on The Darkness has been awesome. Only 5 issues in.
The current direction of Spawn is very dark/noir. Jump on at 201 or 220
The Shadow by Garth Ennis. Pulp/Noir/WW2 Vigilante awesomeness
The Spider by David Liss, similar kinda thing albeit modern day.

To get away from crime noir books;

Saga over at Image is extremely popular. Itis a fantastic book by Brian K Vaughn. Intersteller war, love, fantasy book.
Manhattan Projects by Jonathan Hickman. Sci-fi WW2 conspiracy book.
Prophet. Euro-style world building sci-fi.
Morning Glories. Mindbending mystery/sci fi series. Lost meets Runaways.
Invincible. Fantastic superhero book. Oney of the best on the shelves.
Walking Dead. Very popular zombie series.

And Valient recently relaunched their universe. All have been great so far.
X-O Manowar, Harbinger and Bloodshot out now. Archer and Armstrong later this month. Shadowman in November.

Thanks for this list! I've actually checked out a few from it and love what I'm reading so far. The mini descriptions helped to point out what I wanted to look into more.

I'm looking for some more mature aimed comics other than the major marvel and dc heroes.

I myself enjoyed Rasl, Long Halloween, etc. Things of that nature that are deep.

I would think Bloodshot would be up your alley. Hero dies repeatedly (generally in a very gory way) as a strategy rather than as a defense mechanism. Explores some psychological issues as he discovers all his memories are compartmentalized and stored, to be triggered by the agency that deploys him for motivational reasons. It's the only title in Valiant that is not quite to my taste, but it sounds perfect for you.
