Gamer's Paradise: Axis & Allies WWII Expansion ($20)

    Add submarines, air patrols, and increased industrial
    production that introduces destroyers, destroyer escorts,
    and cruisers.

Gamer's Paradise: Axis & Allies WWII Expansion II ($25)

    Adds German SS, US Marines, British commandoes, paratroopers,
    trucks, artillery, and includes 80 colour counters.

Gamer's Paradise: Axis & Allies WWII Expansion III ($50)

    The bombing of Tokyo through the historical events that led
    up to the Battle of Midway are re-created here.  The vinyl
    map is 76cm by 127cm (30" x 50").

StratoMax: Max's Advanced Rules ($10)

    This expansion contains 20 optional rules, including
    paratroopers, kamikazes, strategic bombing raids, escort
    fighters, and expanded weapons development.  Since it is
    a rules-only package, it uses existing A&A components.

Xeno Publications: The World at War 1939 - 1945
 (Map and rules $20, playing pieces $30)

    This is actually two separate packages.  The first includes
    a map for new territories, and the new rules, which include
    2 new players (France and China), rail movement, and political
    influence.  The second package includes 238 new plastic playing
    pieces, including sub pens and a new ship type.  You may wish
    to paint a dot or other unique mark on the Chinese and Japanese
    units to distinguish them from the US and British units,
    respectively.  It can be difficult to tell them apart at times.
