What kind of game are you looking for? Action, adventure, story, ...?
The Walking Dead game: Mainly story.Deus Ex Human Revolution: Story, action.
Indigo ProphecyHeavy RainAlan WakeI'm assuming this is what you mean by "dark" games? They're all mystery/crime games with not a lot of action but a LOT focused on the storylines.
The walking dead doesn't look very promising.
I'm surprised nobody mentioned any of the Devil May Cry games, they have a dark and grim theme.
