Level 17 appears to be the interior of a cargo ship spanning hundreds of thousands of square kilometers, with a majority of the level being composed of corridors and stairwells. Occasionally, one may come across a flooded hallway. Remaining in this flooded hallway for a long period of time will eventually transport you to Level 7.
While mostly devoid of entities, there is one species which is exclusive to Level 17. Imprints are entities that appear identical to those who have previously explored '''Level 17''' and mimic the the exact movements the explorer made throughout the level. While not physically dangerous, looking at an Imprint causes great amounts of distress, and looking one directly in the eyes is able to put you into a comatose state, the cause of which is unknown.
Upon an Imprint reaching the point at which the explorer it is echoing either leaves the level or perishes of unknown cause, they simply fade away, before reappearing at their "entry point" after a period of 24-72 hours.
Heading up several flights of stairs will eventually bring you to the "upper" floors of Level 17. While appearing to have glass windows and doors with "light" coming from them, they cannot be opened, nor can they be broken. Being directly in the light emitted by these objects causes you to begin to suffocate, as if underwater. This persists until you either moves out of the light, or until you asphyxiate to death. Along with this, Windows are occasionally able to appear here, although they are extremely uncommon.
Heading down any flights of stairs will lead to the cargo hold of the ship. Huge cargo containers span the bottom of Level 17. These cargo containers are usually empty, but with some full seemingly random items. These containers are placed awkwardly in the middle of halls and doorways, blocking some paths. The stairs continue downwards, but are inevitably blocked by a gigantic cargo container.
