Mutant Year Zero: Road to Eden

This is story related and functions as the end of your tutorial for the game. Note, you can sneak past enemies, even the ones the game prompts you to kill. You may have to kill the final small group that is right beside the elevator to the Ark before it becomes accessible as a zone travel, but either way, once you can zone to the Ark, simply approach the zone travel (you can always see available ones by holding ) until you zone into the Ark and watch the cutscene explaining your main story mission, your achievement will pop and you’ll be on your way!
