The left side has the engine control, health and noise meter. When you take control of the cyclops, there are 2 sides that have different things.
I was out in the lost river while taking these photos. There's a ladder to climb down into the lower levels as well as a color HUD to change the outside color of the cyclops. This is the captains room, it has a HUD for the cyclops health which marks where damage is as well as fire. It's basically the room you always want something in, especially an important thing. This is the airlock room, it has enough space for a bed and any other things you want to put in. This is the vehicle entrance/decoy tube area, you can enter your vehicles from the hatch and also load a creature decoy in the tube, but it's blocked by my growbed.
This is the left view of the engine room, it has another 3 power cells that the cyclops will use after the first 3 are dead, it also has an upgrade fabricator to make all the cyclops upgrades. This is the right view of the engine room, it has 3 power cells that the cyclops will always use first before using the other power cells as well as an upgrade insertion area.
