It adds, among other things:
- A better recognition manual.
- Great new sounds.
- Many more cities.
- "Living" ports full of ships.
- Historical events.
- More vessels and aircraft.
- Much more realism, including a new, more real damage model.
- The Red Cross (yipee:p!).
- Better graphics, including a mod that increases view distance.
- Many, many, many more radio messages.
There are two things to consider, though:
- Is your computer up to it? Grey Wolves needs a good deal of memory to run.
- Do you want a highly realistic experience? If not, Grey Wolves may not be for you.
