Sunset Overdrive is in a playable state and has "passed its vertical slice" according to Microsoft Studios Corporate VP Phil Spencer, which in non-management speak means it's been demo-ed successfully. Speaking to Polygon, Spencer said, "We're playing a full section of the game and feeling really good about the open world gameplay that they've put together. I like the investment around new IP at the launch of a new console."
Insomniac hasn't revealed too much about its stylized open-world shooter, which looks to be an over-the-top, vibrant multiplayer game like Fuse once was. With Spike TV's VGX show around the corner, we wouldn't be surprised to hear more in the near future.
