Supererogatory spotted the unannounced development studio's website (replete with strange video). In a Digital Development Management brochure (warning: PDF link), the studio is advertised as having one "Original IP with major publisher" in development and one "Licensed IP -- TBA," though it's said to be working on games for Xbox 360, PlayStation 3, PC, iPhone, and Facebook. A quick search on LinkedIn shows that the dev house has been picking up employees from the likes of Obsidian Entertainment, Pandemic Studios, Red 5, and EALA, and will be focusing on "3rd and 1st person character action" titles. It also appears that some employees have been with the studio for over a year, meaning it's not exactly a brand new venture.
Odder still, it appears that one Douglas Markland of Killspace Entertainment is down as the contact on a WHOIS of both ApocalypseNowGame.com and WarIsNotAGame.net (though both sites are still devoid of content as of this writing). We've reached out to the studio for information on any of this and will update this post if we hear more.
