An Unreal Engine 3-powered iOS game by Mythic Games coming soon (expected in Q1 2014). Official screenshot(s): Official development blog: nightmaredeveloper.blogspot.com
I see. So, the video is from the iOS game, not the PC/Mac game. However, it is noted that the video was posted on Dec 9, 2012. From what I know, at that time, the game was called Nightmare: Among Shadows for both PC, Mac and iOS. In Feb or Mar 2013 (I don't remember exactly), Mythic Games split it into two separated games, Nightmare: Among Shadows for PC/Mac and Nightmare: Into Darkness for iOS. As such, the video you see is actually from the iOS game at that time, Nightmare: Among Shadows. The current iOS game, Nightmare: Into Darkness is a little different game which only has one screenshot being released (above).
Nightmare Developer Haha you found my game sweet! I am currently working on Nightmare : Among Shadows for PC and Mac Into Darkness will be released shortly after and will be a bit different than among shadows though taking place in the same universe. Really cool to see it made it onto here by chance. I am also the gameplay programmer for another game on here Surreal System. Though there is no set date for into darkness you can expect it early next year! Thanks.
