A very flexible ruleset for historical WWII adventure gaming. Also includes guidance for running super science, occult, and even space games. Heck, you could run OD&D Modern with it, if you wanted to. Thumbs up!
If you're thinking about taking WWII: Operation Whitebox for a drive, you should definitely get this module. It consists of three short commando raids set in Norway, each one good for a play session. Would make an excellent start for an Operation Whitebox campaign. Recommended.
