Arrival: Module 2 – Terraforming Earth

Adds dynamic environmental systems that force players to manage atmosphere and weather across a tidally locked planet. Players pilot vehicles between the permanent day and night hemispheres, contend with a hypercane event that strips nightside atmosphere, and respond to episodic dropstones that rebuild it. New rules model runaway water disassociation and a thermal tide event, creating shifting risks and resource pressures that affect survival and movement. Components and events change how players plan routes, allocate protection and life-support, and react to sudden planetary shifts.
