Okay so I just heard about this game and am really excited about it.

It's basically a steampunk-ish stealth action game set in an open world and the AI is dynamic, which makes me think it's similar AI to the Stalker games. You get melee weapons, guns, and you have special powers, such as stopping time, that you can get. They're really going for player choice as well and one of the lead developers worked on Deus Ex.
I'm currently reading this interview with the developers and some of the stuff they're talking about is really cool, especially the part where they talk about testers doing stuff they hadn't thought of while testing the game.
Harvey Smith: Yeah, or I took these two powers and they work in combination that was not planned, but I tried it and it just worked. All the time we saw testers do things we never planned. Like, the time stop power. A guy runs into a room, there are six guys – and six guys in our game is serious problem – so he stops time, then he puts an arrow in the air, an arrow in the air, an arrow in the air [air-draws a semi-circle in front of him]… Anything touching you moves at real-time, so if you bump a lamp it falls, but as soon as it’s half a second away from you it stops. So if you hit a guard, he animates but then stops. So the crossbow bolts leave you for half a second and stop, and then when time resumes all the guards die at once, they all get hit by crossbow bolts at once. And it was magical the first time we saw somebody do that. It’s just this general purpose approach to making game systems.
I can tell you crazy ones, like a guy stops time and as somebody shoots the bullet hangs in the air, then he possesses the guy, walks him around in front of the bullet, and then ejects and then when time resumes the bullet kills him. He suicided in this weird way. There’s all these crazy combinations that we had no plans for, but we trust that if we make things general purpose, the player can get creative. It’s super-cool. That’s our main thing about the game. On one level, you’re a supernatural assassin in a retro-future world, but on another level there’s a lot of variability in this game and it’s ultimately going to be your playthrough.
Can't. Fucking. Wait.
