eGhosts NPCs and can either harm or help John during his search
Blue ghost - The most common ghost. Walking into one results in a small speech bubble and occasionally a resource
Big Blue ghost - These ghost are either indicators of a large item or multiple items. Sometimes its also for a sidequest.
Shining Orange ghost - Indicator of a key item, usually for the rocket.
Orange/Red ghosts - Not to be confused with the Shining Orange ghosts, these ghosts are impatient and will harm John if he comes into contact with one. Sometimes these ghosts directly block pathways.
Night ghosts - At night, John will automatically be attacked by ghosts if he dose not retreat to the Opus Rocket Factory. This can be avoided to search longer with the camping equipment but only once per night.
