Crew Size: 83 Men

Remaining Oxygen percent upon surfacing: 5%


Remaining Battery Charge upon surfacing 1%



(Speed was 3 knots, until battery charge dropped below 10%, after which time, speed slowly decreased to 1 knot, which was the underwater speed just prior to surfacing.)


It is true that the Co2 indicator pops up when Co2 levels are over 10%, however you can safely ignore it - focus on your overall level indicator which is located at the bottom right-hand corner of the screen

did you test CO2 range with a different crew size to see if you could stay under longer with less crew or shorter with more crew?(not sure you can get more than 83 in a WWII sub)
