The Gold Chest
Sometimes, a gold chest is enclosed between two walls, if you manage to get to the same level than the chest, you can access it by going down a hidden rope and then going to the right.

Secret Area
Contains a secret area found by going off the ledge past the cabin area and entering a tiny crevice in the wall. Must at least have Photon Jetpack or you will fall past it.

UPDATE: In this area there are three golems dancing around a beatbox. Getting close to the beatbox will stop the normal musica and play an electro-dance theme. This DOES NOT require the Photon Jetpack, buy maybe having a couple Rusty Jetpacks can help thanks to the reduced fall speed.

Map
In the middle of the map there are 4 closed rooms which require 1 keycard each to be unlocked - Medical Bay, Cabin, Armory and Storage.

The Medical Bay contains several medical beds with little cabinets besides them. Opening them will give you a large heal, as well as the chance of an item. There is also a large surgical bay that you can teleport to the final boss fight. Activating it during the final boss fight will heal you and your drones fully, although it has a long cooldown before it can be used again. There are also chests in this area.

The Armory contains a large Gauss Cannon that you can teleport to the final boss fight. Activating it while Providence is in front of it will deal a large amount of damage to him. It, like the surgical bay, has a long cooldown before it can be used again.

Various little indicators on the ground will show you a map of the ship and where you are when you are over them.

To the right of the map you will find a computer asking to take you home. Press "A" and prepare to fight Providence.
