Sony Computer Entertainment is teasing what appears to be a brand new game for Playstation 4.

Featured above, you can view a trailer for a game that is currently known as “Emagon.” The reveal came via a PlayStation Spain Blog Post, in which Sony Europe Software Product Manager Javier Borrego teased the video:

“As many of you know, this week, the Playstation is 20 years old. This is a very special time for us, we never thought we’d get this far when our company launched the PSone back in 1994. So, we prepped something up for this occasion. Unfortunately, you’re going to have to wait to know what it is. Featured above, you can view a mysterious teaser labeled “EMAGON,” and a date: December 5th. On that day, you’ll know our best kept secret.”

The trailer features the voice actor Roberto Encinas, known for his work in a multitude of Sony Computer Entertainment-developed games like Uncharted 2, Killzone 2, and various notable third party games as well.

Here’s an English translation of the teaser:

“20 years is a lot of time. If you look around, you’ll see everything you’ve obtained. You’ve dominated in an infinite number of places, you’ve conquered and you’ve been freed. You’ve created and destroyed. You’ve fought with light against darkness. However, things are different this time. This time, it’s the real deal. For the very first time, your input has direct consequences. They need your help, and I know that you can hear their cries. The power to change the world is in your hands.”

The reveal is going down on December 5th, just before Sony’s Playstation Experience conference. It’s worth noting “Emagon” is “No Game” backwards.

What could the game be? A Project Morpheus exclusive?
