Mods
Many mods have been produced for Silent Hunter 4. Some of them have been combined into major mods such as the realism-focused Real Fleet Boat mod (the successor to SH3's popular Real U-boat mod) and the Trigger Maru mod. These mods combine popular gameplay and realism mods as well as unofficial bugfixes so that players have a 'one-stop' modding solution that prevents potential confusion over the hundreds of mods that are available for the game.
