Two more of the high profile titles that did not make the cut of the Activision merger with Vivendi Games have now been picked up. Ghostbusters: The Game and The Chronicles of Riddick: Assault on Dark Athena will published by Atari.

Both Ghostbusters: The Game and The Chronicles of Riddick: Assault on Dark Athena had been rumored to have been shopped to several publishers before landing with Atari. 50 Cent: Blood on the Sand was also recently picked up by THQ, which leaves only Brutal Legend, which was being developed by Double Fine Productions, as the only title that was dropped from the Activision merger with Vivendi still unable to find a home.

Some of our sources are insisting that Atari has also worked out a deal with Universal to allow it to develop additional games based on the Chronicles of Riddick movies beyond Assault on Dark Athena title that was already in development.

Some have suggested a similar deal had been pitched to Sony pictures who own the rights to the Ghostbusters movie franchise to extend development of future titles beyond the one currently in development, but as of yet no deal has been reached.

Atari was said to have worked out a flat fee deal with Activision to cover a portion of the development costs associated with the two titles so far, but details as to the exact nature of the entire deal remain a bit unclear.

As for expected release dates, Ghostbusters is expected to be released at some point early next summer so as to tie in with the movie’s 25th anniversary. As for the Chronicles of Riddick: Assault on Dark Athena, it is slated for the spring of 2009.
