Dishonored
A 2012 game from Arkane Studios and published by Bethesda Softworks. Along with at least one guy from the Half-Life 2 peoples.
I know anyone who gets Game Informer has seen this game and I can't wait for it.
You play as the ex-royal bodyguard to the queen of a dystopian future society. The queen has been assassinated and you've been made to look like the killer. You've become Dishonored.
You've joined an underground rebellion, and your actions will shape how the world changes around you. Gameplay is broken down into sandbox exploration, stealth, melee combat, and magic.
Everything you do has multiple ways of being completed, and each different way could potentially affect the current situation and several ones after that. For example, you come across a woman being attacked in an ally by some thugs. If you walk by, it might turn out that she was an informant for the resistance and with her death you lost a valuable source of information. If you save her though, she'll share with you more information than usual something.
It's shaping up to be a great game from what I've seen, and I honestly can't wait for it.
