Orca individual room features

The diagram does not visualize the 'staircases' clearly, however this should be clear without.

The electrical box wiring connections will be inspected after the basic overview.


There are two minor blind spots on the Orca, a small area behind the engine, and the area above the glass window above diving suit lockers. Unfortunately, the majority of Orca underbelly is in a blindspot, including the front (nose) - meaning its best to approach targets from below.

Default wiring in electrical

Bellow we find the default wiring in the electrical room junction boxes. Highlighted are key components that should be kept powered ideally.

Additionally, here we can see the electrical and mechanical device positions within the sub - red lines represent separate submarine rooms. This image is taken from the status monitor aboard the submarine.

Things to note

• Stock speed and turning is subpar- however when upgraded allows to outrun smaller creatures with ease.
  
• Both junction compartments flood easily due to outer positioning - this causes a lot of damage to the boxes. When not flooded, Orca junction boxes get fried consistently, requiring constant monitoring.
  
• Glass window above diving suit locker is breached easily; the airlock and docking compartments flood easily, and act as a flood buffer for the command room.
  
• The general stairway structure of the sub allows for easy descend into reactor and engineering compartments.
  
• Substantial storage across the entirety of the submarine, allowing for good organization.
  
• Ballast access is spread out, requiring moderate travel between each.
  
• 4 fire extinguishers - beneficial due to a substantial amount of fires that can occur.

Upgrades available
