This article has a talk page!This is a sub-page of Ghostbusters: Sanctum of Slime.
The following source code was found embedded inside the main Sanctum of Slime executable, from 0x4CD0B0 to 0x4F6365, in the PC (Steam) version of the game. This source code is not in the PS3 or Xbox 360 versions.

This needs some investigation. |
