Just when you think you have a handle on your resource management, the weird and wonderful mysteries of space travel come knocking at your dome: Mysteries Resupply Pack, the new free content pack for Surviving Mars, adds three new mysteries for players to investigate and survive. New mysteries afflicting the colonies on Mars include: • St. Elmo's Fire - Colonists find it hard to get a good night’s sleep, especially when mysterious lights begin appearing where they have no reason to be. What is causing these unexpected apparitions and is it connected to the confusing changes in the water supply? • The Philosopher's Stone - Encounter beings that are a far cry from the fleshy bags we call carbon-based life when the colony stumbles upon entirely crystalline entities. Are they here to be of assistance or only out to protect the family jewels? • Metatron - Colonists look to the sky agape as a great floating monolith has parked itself directly above your fledgling colony. Does it come in peace or is it even sentient? Either way, it is certainly blocking the views from the dome!
