It is a light war game that is midway between Risk and Axis and Allies in complexity.
[citation needed] The game is loosely set in the 1930s and includes plastic pieces featuring tanks, planes, infantry, and artillery.
The Expansion added technology cards, trade route cards, and Production Points as well as the Eastern side of the world which can be added onto the western map board to make a gigantic map of the world Earth circa 1935.
Technology cards are gained by a player if one successfully rolls a 10 or higher with the blue dice.
Every time 5 P.P are expended, the dice roll number needed to win a technology card is subtracted by one.
Technology cards give players certain advantages such as tanks that require three hits to destroy or planes get one extra die roll in battles.
Another vital factor in the expansion is political cards, which are gained every time a successful diplomatic blitz or at the end of the round is conducted.
