As reported by PlaystationLifestyle.net, Thierry Perreau (Creative Director at Neko Entertainment) lists work on a Halloween video game on his LinkedIn page:
[Translated] Halloween (from the film) for the Wii, the Xbox 360 (Kinect) and the PS3 (PS Move)
Unfortunately, there are no other details regarding the project, so this could be an abandoned demo used for a pitch or a new game they are working on. Given the listed motion controllers, we expect that this project was recently worked on or is still a work in progress.
The chance of this particular Halloween game seeing the light of day is anyone's guess, but The Weinstein Company recently announced its push into video game territory, and Halloween was one of the mentioned properties. Would you be interested in playing or escaping from Michael Myers in a motion controlled video game? [Thanks STYD]
