• What is [VH] The Iroh - Old Version? Why are there two submarines in this workshop file?
  The Iroh was a really strong submarine with stats going a bit over the top. On August 2022 I've updated it to be more in line with the general balance of the game.
  While I prefer to play on the current version, and strongly suggest to new and old players alike to use the new one, some people may prefer to play on the Old Version for an easier playthrough.
  
  
• The Iroh has been updated, will this affect my campaign's sub?
  No, changes made to the submarine will not have any effect on your submarine inside a campaign.
  
  
• How do I switch from searchlights to the gun in the Magnetic Shield's room?
  In Navigation, on the Navigation Terminal, there's a little switch on the right of the periscope.
  
  
• How do I switch from one searchlight to the other?
  Click.
  
  
• How do I launch the Depth Charges?
  You can launch them from the terminal in Gunnery.
  
  
• How do I use the Electric Discharge Coil?
  You can activate it from the terminal in Gunnery, or from the Navigation Terminal in Navigation.
  
  
• Why can't I move the submarine with the terminal in Gunnery?
  That terminal is not meant to move the sub.
  
  
• Can I make a copy of the Iroh and post it on the Workshop?
  Yep
  
  
• Is this ship BOT friendly?
  Yep
