"The game is not a direct port. Instead, Spiral House was contracted to modify the original codebase by Sick Puppies to make it more user-friendly for the consoles. This includes a complete overhaul of the interface to make commands easier to access, the introduction of battle elements - next to the regular missions - to speed up the game's pace, a more linear game structure, and a redesign of the control over ghosts. They now have less AI and there is more variety in the types, requiring you to tap wisely into the plasm pool to deploy the most adequate ghost for each situation."
