It looks like someone saw a ghost, because the Ghostbusters have been called. This time they aren’t packed on a retail disc. Atari and Sega have announced that they are teaming up to bring gamers Ghostbusters: Sanctum of Slime for the PlayStation Network along with the XBLA and PC.
The game is being developed by Wanako and puts players in control of the rookie who was hired by the Ghostbusters in the first game. The game will be 4 player, both online and locally, and will be a top down shooter. It will feature plenty of big bosses and new weapons, but will sadly not feature any of the voice talent from the original movies.
