Demonik is a cancelled action game that was in development by Terminal Reality. The project was canned by the publisher, Majesco, for economic problemsIt was supposed to coincide with the film Grandma’s Boy (there’s a scene in the film in which they play this game).
Dead Rising is an action adventure / survival horror developed by Capcom and released in 2006 for the Xbox 360. As we can read on Wikipedia, Keiji Inafune, designer of Mega Man and Dead Rising, wanted the main character Frank West to be different from the usual Japanese main character. Instead of having a young and beautiful protagonist, he wanted an everyman that looked average rather than beautiful or ugly. Before chosing Frank’s final design, they created different models (especially for the face) that can be seen in the beta screenshots below.
Also, as noted by DCodes7, in the beta Isabella is holding a sniper rifle, but she never holds that weapon in the final game. Isabella’s brother Carlito is the only one who uses the sniper rifle.
In another old screen we see Frank reuniting an old couple in the middle of a zombie apocalypse after being separated. One think to note is that Frank reunites the old couple on the roof of the mall in the final, not at the entrance of the mall as shown in this image.
The camera HUD is different. In one of the images it shows the battery life of the camera exceeds 30 (thirty), in the final version of Dead Rising the cameras battery life is 30+ (thirty). Meaning that the battery life of the camera cannot exceed thirty, but the image shows that the camera battery life exceeded past 30 (thirty) in the beta. There are other small details of the HUD’s camera that are different from the final.
Created by Silicon Knights, Eternal Darkness was an interesting game for the nintendo 64 that seemed to be able to bring new life to the Survival Horror creating the first “psychological thriller”. However, it was later ported to the Gamecube. Was it really never released for the Nintendo 64 or it was just an insanity effect ?
