GamesAreFun has pointed out that according to some recent job postings, Midway is currently looking for a little help in developing a possible Area 51 sequel, called Area 52, of course. According to the listings, the game will most likely appear on the 360, PlayStation 3, and PC. Sorry Ninty fans, no Wii.
There is also another new IP listed as Criminal for the PS3 and 360. Area 51 was a decent FPS, so it'll be interesting to see what direction Area 52 will go. We can only hope David Duchovny will make a return appearance.
