This is fun and immersive. Have you played "Havoc in the Hamak Sector?" Certain audio communications have background sounds, including a red alert klaxxon, weapons firing, and explosions.
Players can find audio communications frustrating, though, if they can't understand the message. Or is that part of the mission?
My experience with audio communications has been mixed. They definitely add to the feel of the game, but since you cannot predict the hardware that another crew will have you don't know how it will sound playing from their main screen computer. Also, there are international players who can read English at their own pace but may not understand spoken English at your pace.
Yet I plan to press on and do more missions with Audio Communications.
"Damn the torpedoes! Four bells, Captain Drayton!"
(Likely actual words of Admiral David Farragut, USN, at the battle of Mobile Bay. Four bells was the signal for the engine room to make full steam ahead).
