And for some reason, a strange phenomenon that couldn't—no, shouldn't—be happening to the Captain is occurring.

Please explain why I am getting a "virtual environment has been detected" alert that then kicks me out of the game when I just downloaded the game from the Google Play store. I even tried uninstalling and reinstalling just to face the same issue. Since there is clearly something wrong with the game and I can't even get a chance to login, I'm rating it at 1-star until this is fixed.

"Here, download our game...you'll have to wait a day to play." Then why bother releasing it?! I remember when spps were playable ON RELEASE. The kicker is this game might not be f2p friendly from reading threads about it.

One of the best experiences I have ever had. My experience playing it went from twenty minutes beta to five continuous hours without getting bored. The story is amazingly deep and scary. The animation and gameplay change perspectives during combat and the animation changes from 2D to art, with the creativity of the characters can die and their different stories. An experience that deserves five stars with merit. can't wait for the launch!
