Copenhagen-based developer Ultra Ultra has announced that its third-person science-fiction action-adventure game, ECHO, is poised to finally release for PS4 and PC on September 19th. And to celebrate the announcement, the developer has released a brand new trailer.

For those that don't know: Ultra Ultra is a studio consisting of eight people, most hailing from Hitman developer IO Interactive. The studio was founded in 2015, and ECHO is set to be it debut game.

The following elevator pitch of the game is provided by the developer itself:

After a century in stasis the girl En arrives at her destination:  A Palace out of legend, a marvel of the old civilization eons gone, still awaiting its first human occupants. Out here, using forgotten technologies, she hopes to bring back a life that should not have been lost...

According to Ultra Ultra, ECHO starts as a character driven journey of discovery, but slowly unfolds into something "more punishing," as you dabble in the aforementioned's Palace magical technologies. Studying everything you do, everything you are, it quickly becomes apparent the Palace has a will of its own.

The Palace is said to create Echoes -- exact copies of you in every way. They behave like you and do things just as you do. Thus, the way you play the game will shape them -- and they are your enemy. If you run, the Echoes will get faster. If you sneak, they get stealthier. You shoot, they shoot back. The Palace and Echoes constantly react to your every choice and input.

The Palace also apparently "reboots" every few minutes, resulting in a blackout. This blackout-cycle is the rhythm at which the "Echoes" get updated with your latest behavior, learning and unlearning from your actions. During the blackout, the Palace is blind and you are free to act without it watching your or with any consequence. Aka, this is the time to run and gun and do everything that you don't want the Palace to see.

Ultra Ultra has confirmed that the game will  support PS4 Pro -- but in what ways it will take advantage of the supped-up machine remains to be seen. Further, it's also unclear how much ECHO will cost when it releases.
