Silent Hunter Online is a free-to-play, browser-based multiplayer submarine simulation game developed by Ubisoft Blue Byte. For the first time in the Silent Hunter series, players will command multiple submarines at the same time.
Manage your fleet, construct new U-boats and replenishing supplies are all important aspects of your duties as a fleet commander, and you can access the bunker and depot of your home base at any time to do this.
