The rel_triggermaru_overhaul.7z file you have requested: Major Mods / Trigger Maru / TriggerMaru Overhaul for v1.4 - 272.22mb is not available. Perhaps try browsing all files for the game Silent Hunter IV: Wolves of the Pacific and upload any files you want to share or are missing. This is the only information we could locate:
This is Ducimas' first and last version of Trigger Maru Overhauled for version 1.4. Please note it doesn't work with version 1.5 (U-Boat Missions add-on). If you wish to install Run Silent, Run Deep - The Campaign with this, use RSRDC v370 (you'll also need v370 patch 1 and the RSRDC Crash to Desktop Fix).
