What you're seeing in the video is supposed to be the game itself. They've also stated that they're using the Unreal Engine 3

"Driven by the powerful and versatile Unreal Engine 3, the new title will feature sharp visuals, almost unlimited and visible weapon customization and unique superhuman powers. The new title also offers a variety of maps and modes in new PvP matchups, such as the intriguingly named Crystal Boost mode, giving players the opportunity to acquire and use their superhuman powers."

Here's hoping it'll be good!
