Upper Gun Deck

Purpose & Position
The Upper Gun Deck is a deck on top of the Submarine. It's used to fend off aerial attacks, but lacks the 88mm deck gun the Lower Gun Deck holds and is therefore unable to attack nautical targets. When the submarine is surfaced, it is wise to man at least one of the two gun decks for protection against planes (if those are present on the mission).

The Upper Gun Deck can only be accessed when surfaced. If the player attempts to access the gun deck when the submarine is submerged, they will drown. The only room from which the gun deck can be accessed from is the Sensor Room.

Platform Ring
Around the platform is a 360 degree uninterrupted ring on which the .50 Cal machine gun is mounted. This is in contrast to the interrupted ring on the lower gun deck, so the upper gun deck is technically the superior platform for taking on attacks from the air.

.50 Cal Machine Gun
The .50 Cal Machine Gun is mounted to the ring on the platform on which it can be moved sideways. The .50 Cal can also be angled up, down and sideways with the handle on the back and fired with the handle on the left. It is recommended to get the .50 Cal in a roughly accurate position and to then adjust aim more precisely with the middle handle, while using the left handle to fire.

Second Platform
The player can access the second platform by opening the door on the upper gun deck. There, the player is outside of the ring and can peek down at the lower gun deck. Currently, this serves no real purpose other than offering the player a different perspective.
