Early footage shows footage of the original game mixed with early preview of the early mobile port, which at the time has been using the assets from the original game, collections (possibly initial version of ghost collections) showcase several enemies / ghosts in their old model appearances, It's unknown if it was running on the old engine or a new one (Unity).
