The World at War 1939-1945 was the first unofficial Axis & Allies expansion, published by Xeno Games.
Many of the rule changes found in the later Axis & Allies Revised & Anniversary editions (such as the 2-hit battleships, "1/2 battleship" destroyers, artillery guns) were original innovations in The World at War, first published in 1990 with 238 playing pieces and a new 24"x36" map that added more territories. As an expansion, much of the 1984 edition of Axis & Allies was needed to play this expansion.
The World at War 1939-1945 2nd Edition, published in 1993, balanced some of the gameplay and added some new ideas but retained the same glossy 24"x36" color map and pieces.
The 3rd Edition, published in 1996, continued to improve gameplay balance and added Atomic Bombs to the technology development. After developing A-bomb technology, players spend 6 IPCs to buy one, which must be delivered via a Heavy Bomber (also a required technology). Damage to a land or sea zone by an A-bomb eliminates 20 IPCs worth of enemy units and renders the territory desolate (-5 IPC value, with +1 restoration each turn for two turns), causing devastation to the economy as well as military of an opposing player.
