So, I'm completely in love with dystopian/post-apocalyptic/grimdark settings, and I was wondering if there are any more bleak Mecha series that would cater to my tastes? Something with little-to-no hope for the protagonsits?

I really enjoyed the BLAME! mangas, NGE, Betterman, most UC Gundam series, Vandread, etc.

I really can't stand series like TTGL, G-Gundam, Star Driver or anything like that. I know this may seem like a childish request but it's the only kind of story I can enjoy.
