Essentials - You will need to activate the three power switches, have the zipline handle and dynamite. You will need to have the Frozen Crevasse, Lagoon, and the Sunken Path (which you will need to go to the artifact room and shoot the pipe over the fire) open.
Gearbox - you will need to place the dynamite in the top area of the map. Once exploded next to the railing there will be a gearbox that you have to pick up and take to Hermit. Once he drops it back down you will have to place it back there.
All Parts - You will now need to use the flinger. Once you launch you will land on a wood box which will then have the part. You will have to fling over to three locations that all have the wood box.
Craft - You can craft the Heat Pack at the Gangway, Lighthouse Station, or Specimen Storage.
