In advanced mode, the morse key functions like it does in real life. In simplified mode, players type in messages using the keyboard, but unlike before, the message can be typed out in full, without having to pause between each letter while it is being sent. The mode is set in the lobby settings before starting the game.
The new system has two modes: Simplified and advanced. UPDATE March 27, 2020: New radio system with Morse code. Step close to the voice tube and call out for the men in the control room. The voice tube allows communication between the bridge and the control room. There is a voice tube on the bridge that connects to the control room. UPDATE May 23, 2020: Wolfpack now features in-game voice chat with two options: simplified, where you can talk with any member on your boat no matter where they are on the boat, and Realistic mode, where you can only speak to players in the same compartment as you or talking through the hatch. Size and number of merchants varies dynamically, escorts patrol in realistic manner, and as long as you are not detected, you can maneuver in from of the herd for a salvo or a series of well-placed torpedo shots. The convoys are randomly generated just out of visual reach, so you will want to dive and locate with the hydrophones. Currently, Wolfpack is still considered Early Access but the game features the backbone of WWII U-boat missions: Open ocean convoy battles.
