The Grey Wolves - Freeware expansion pack for Ubisoft's 'Silent Hunter'

About The Grey Wolves

UPDATE: Journey's End for The Grey Wolves Mod Team


Building on the success of our expansion packs for 'Silent Hunter 3', in early 2009 the team began creating the next installment in the GWX series: GWX4, a freeware expansion pack for 'Silent Hunter 4: U-boat Missions'.

Unfortunately, due to the team's real life commitments and the likelihood of many of our objectives for GWX4 being mirrored in Silent Hunter 5, the GWX4 project is officially cancelled and the team disbanded. For further information, please see the link below:

The Grey Wolves comprised a team of programmers, tweakers, 3D-modellers, artists, designers, testers, team managers and other contributors from the thriving international sub-simming community.

We produced high quality freeware expansion packs (or 'add-ons') for Ubisoft's popular 'Silent Hunter' series of U-boat simulations.

Since 2005, The Grey Wolves team fixed, improved or added new features to virtually every aspect of Silent Hunter 3: realism, gameplay, models, graphics, sound, historical accuracy, interface, music... Anything we could throw our collective talents at.

From the beginning, our aim was to give fellow Silent Hunter enthusiasts an immersive yet playable WW2 U-boat simulation — not only for your enjoyment, but for the sake of history.

In Appreciation

To all who are and were veterans of that horrible war, both military and civilian, that paid its price. All gave some. Some gave all.

We have not forgotten you.
