Contained within the hull texture file of the HMS Edinburgh, a Pile of Gold can be seen, only visible in the texture file, as it does not appear to be visible on the model at all.
This is just one of about a half dozen Easter Egg’s I am personally aware of. If you are unfamiliar as to why there is this Easter Egg on this particular ship, when the HMS Edinburgh was sunk by U-456 in April of 1942, at the time, she was transporting 4,570kg of gold. With a value of £1.5 million sterling in 1942, (adjusted for inflation to 2016 currency, £63,047,983 EUR, or if you’r american $70,807,298 USD) as a payment by the USSR for war supplies.
