Fixed some sprite depth issues related to wiring.

Changes in this version:

• Added logic so ducts don't open if the room below is flooded
  
• Added third periscope to the top rear to allow the captain to scout or help spot for the back gun
  
• Oxygen generator and lights now shut off when on emergency power, dropping idle load from ~1600 to ~600
  
• Added lever to force O2 generator to stay on
  
• Added O2 generator status indicator to command room
  
• Fixed pump in Captain's Room not being set to pump out by default
  
• ARC and SRM start on by default, allowing for an quicker take-off with bots
  
• Tweaked door to captain's room so it closes much faster, stopping unwanted visitors and making it easier to climb into the Armory
  
• Tweaked door to Armory so it closes much faster
  
• Added background to ducts so you don't see the wires etc. behind them when they open
  
• Wired up a few water detectors to the flood alarm that weren't yet (mistake in the original Orca?)
  
• Tweaked Junction Room motion detectors so you can walk in and out for a quick check-up without the door slamming in your face
  
• Small tweaks and bugfixes

Changes in this version:

• Reduced power usage of some lights to partially compensate the higher idle power draw of the Mk2. Now running at 1616 instead of 1722, compared to the original 1500.
  
• Fixed the bottom periscope being in an awkward position after the visual overhaul of the original Orca
  
• Fixed flickering of certain lights (problem with relays)
  
• Fixed "SRM" indicator in command room not displaying the actual status
  
• Updated and added images to showcase lastest changes

Fixed some small hull problems, tweaked several systems for smoother operation, fixed a few bugs. Also:

• Removed useless docking port from the bottom airlock, turned it into a proper usable airlock.
  
• Added buttons to control both airlocks from the command bridge, along with open/closed status indicators
  
• Added mechanism to the ballast pumps to compensate for opening airlocks (should prevent sudden rising/falling when entering and leaving)
  
• Added SRM indicator to command bridge

Fixed problems with the Emergency Power system causing overloading on junction boxes. A few small tweaks. Shout-out to KacperRaid for testing.

Added full description. Sub still version 1.0.
