Welcome Aboard. 
There are lots of good mods out there that make SH3GWX fun, exciting and with great efforts put forth to better the realism of this old game.
We would be glad to help you with your basic SH3 w/GWX3.0 game setup.
For enjoyment with adventures in Lone Wolf Flotilla SH3/GWX Campaign play give us a shout through a PM to me for inquires and help.
Regards,
Clay
