Copy the code and paste it as a new quest in San Fran, change location. Swap critters and loot for different loot and critters. Remove machine and machine parts so steam cannot be fixed, but remove boxes that block other hallway. Bingo, another quest.
Do it again in LA. This time swap outside dock image for non-stranded ship moored to dock by ropes. Make ship repairable and operable, limited to coast (to avoid your developer island). Players can keep ship and use as slow, mobile base.
Stranded Rust is a fun quest and many players have commented. Add tons more content to this game like good quality quests and watch popularity soar.
