It's heavy going moving over the surface of LV-426, or Acheron as the colonists now call it. Rocks frequently crumble, rubble and rocks being pushed around by the frequent severe storms, making it pointless to maintain paths or tracks between locations. Because of this, while faster and safer and more comfortable than walking, the tractor isn't fast - managing a speed something like 5-10 km/hr.
The ride back is uneventful. You make several repeated attempts to re-establish audio contact with the colony, but apart from a single garbled panicked transmission, you hear nothing further from them.
It's not pretty - but still, it is a relief when you are able to make out the shape of Hadley's Hope in front of you through the rain and the low cloud.
You bring the tractor through into the nearest entrance, the West Airlock. This lock is away from the main body of the base, and the door is big enough for you to drive the tractor inside. Vehicles can be serviced here away from the constant storm.
OOC:
You can see where this is on the plans on this
plan of the colony on the Level 1 Ground Level image. Confusingly, this image lists a West Lock and a "Hadley's Hope Last Day Starting Location" - it is this second one, the one labeled starting location, that you have arrived at.
As you get out of the tractor - very glad to be out of it, after having been cooped up for so long - you hear a distant voice talking over the intercom. It’s obscured by static but you can make out the following:
"This is an emergency message. All colonists must immediately assemble at the main storeroom on the sub-level for safety."
After several repeats, the message cuts off with an electronic screech.
