Yep, the second paragraph of the article says that the new app will eventually replace both GeForce experience (yay) and the Nvidia control panel (boo).

Yeah the beginning is a bit rough because apparently the alien is specifically programmed to not leave you alone in the first level or two that it appears. My initial experience was similar but after the first level it got a lot better.

To me the game either works great and you get a legit scary experience or the alien pops out at the wrong time and you have to briskly walk through the rest of the level or die instantly.
