The basic game (Attack!) is a very simple game of expansion and conflict set in the World War 2 era. It is aimed at those game players who enjoy rules that are very simple and easy to get into. The game is not intended to be a simulation of the era; but immerses the players in the flavor of the period.

Gameplay:
Each player starts with a few regions (one of which is his capital); and a few military units. Players expand their power bases by adding regions to their sphere of influence. This may be done either through diplomacy (they join willingly); or military conquest (they join; period).

There are three major sub-games in Attack!:
1) Land Combat: A simple system where each unit has certain advantages based on its historical role.

2) Sea Combat: A simple system where each ship type (Battleship; Carrier; Destroyer; and Sub) has certain advantages based on its historical role.

3) Economic: A simple system determines production. The player starts with one card per region owned; and then gets a new one for each new region added. The cards come in four basic flavors (suites): Resources; Factories; Transport Network; and Oil. Each card has a value printed on it that represents the base economic value of that region. If the player is able to create an entire set (one of each suite); he doubles the printed value on those cards. There is also a fifth type of card which has a minimum value of 1 that represents a region without any special economic value (just population).

The units include: Infantry; Tank; Artillery; and Air. These are high quality plastic minis; which come in two sizes: regular for only one unit and slightly larger for groups of five.
The map shows the world circa 1935 centered around the Atlantic (North and South America; Europe; and Africa). The expansion contains the map of Asia; Australia; and the Pacific.
