Game set on the moon
Core Mechanics:
Game takes place on a colonised moon. Human colonies live in massive biodomes which are not easy to travel between.
One day, all communication from one of the smaller domes suddenly and mysteriously stops. This is suspiciously combined with a moon-wide systems malfunction which inhibits the vehicle systems. Transit between domes becomes extremely timely and perilous.
Despite this, your character has been sent to investigate the other dome and see what has befallen it.
They must journey across the surface, using primitive, low range vehicles to travel through outposts and other domes.
Along their journey the character would solve puzzles (including many physics ones to make use of the low gravity) In the vehicle and foot sections that took place outside of the outpost the player would have to be aware of their depleting oxygen level adding urgency to their movements. At one point you would need to collect various parts from wreckages on the surface in order to progress.
The whole time, you are guided and coached over earpiece by one of your superiors in your dome.
