The announcement was made via the company's official Twitter page. Atari notes the game will arrive on the Xbox Live Arcade and PlayStation Network on March 23. Since that specific day is a Wednesday, the PSN version will presumably launch the day before (Tuesday, March 22) along with the platform's regular content schedule. The PC version was not mentioned. Shacknews has contacted Atari for clarification on the PS3 and PC release.
Ghostbusters: Sanctum of Slime is being developed by Wanako Studios, the team that recently launched 3D Ultra Minigolf Adventures 2.
