I'm also beta testing Allies but here is some info from the official readme for the game ( a bit long but it gives the information I most likely would forget ):
Pacific Storm: Allies
Information about the Game
Pacific Storm: Allies is an add-on for Pacific Storm, a unique game about the war in the Pacific. It has the elements of a global strategy, tactical naval war-game and an arcade aircraft simulator. Playing either for the United States, Imperial Japan, or a newly introduced nation (the UK) you walk through a dramatic sequence of large-scale naval and air military operations. The game covers the time from 1940 to 1948. As you play, you can develop new technologies, build and deploy new weapon systems and even change history. Thanks to a smooth and seamless combination of strategy, tactics and simulator, you are completely free to take whatever strategic or tactical decisions you consider best or abandon for a time all strategy and tactics and inhibit any of your units so as to take part in the fighting personally. Pacific Storm's gameplay combines exceptional depth and scale of the strategic mode, superior authenticity of the tactical mode and exciting dynamics of the simulator.
Main Features of the Game:
· Pacific Storm: Allies organically combines three genres into a single coherent all in one game: strategy, tactics and aircraft simulator. After attacking your enemy on the strategic level you may switch to the tactical level and if you want you may inhabit almost any of your units.

· Special unit editor where you can create new units as well as modify old ones is available on strategic level;
· Large-scale naval and air operations on the global map of the Pacific including Australia, Eastern part of North America, Oceania and part of India from 1940-1948. Possibility to change history during the Historical campaign;
· System of experience gain the crew now become more and more experienced with every battle. New possibility of forming elite squads has also been introduced in the game;

· Stunning special effects including nuclear bomb explosions, and astonishing ocean backgrounds;
· A large amount of tactical missions with the possibility to choose the side to play for: Japan, US, or Allies. Tactical battle deployment mode in which one can create any battle on one of the 50 tactical Pacific maps, choose weather conditions and the time of day, as well as units and ammunition; Using this tool one can reconstruct any WWII Pacific battle and take part in it;
· Besides strategic Historical Campaign (composition of forces in the game start is close to historical layout of forces) and Free Campaign (composition of forces is simplified) available in original game, Allies introduce Arcade Mode which greatly simplifies the strategic and tactical part of the game;
· Ability to develop new technologies including increasing the power rating of aircraft engines to guided missiles technology, biological and nuclear weapons;
· Switching from strategic to tactical level (and back) keeping all battle parameters: units' number and their ammunition and characteristics, time of day, weather conditions ;
· Improved game control in the strategic mode allowing effective base management, mission planning and supply management; Rich time control options (slow motion, acceleration and controlled pause);
· A Multiplayer for 8 players with 3 game modes: tactical battle deployment mode, simulator mode, and cooperative mode where two players can join forces in a mission.
Your fleet in Pacific Storm: Allies includes battleships, aircraft carriers, destroyers, cruisers, missile cruisers, submarines and torpedo boats as well as tankers and transports. The aerial war is conducted using fighters (at first piston-powered and in later stages jet fighters), attack aircraft, torpedo bombers and strategic bombers. There are 86 different types of units, all carefully modeled from WWII-era aircraft and ships. Also, you can develop new technologies and create new weapons systems, which may almost instantly overturn the global balance of power. About 100 technological improvements (upgrades) enhancing combat effectiveness of warships and military aircraft are available. In addition to the strategic mode with its 127 different Pacific zones and 40 naval bases, you can play 20 historical battles, including the Battle of Midway, the attack on the Japanese admiral Yamamoto's plane and the battle for Guadalcanal.
Pacific Storm is all about battleships and aircraft carriers — the giants of naval warfare during WWII — about captains and admirals, as well as rank-and-file soldiers and sailors of the two great military powers locked in a life-and-death conflict. In Pacific Storm you can become the Commander-in-Chief responsible for the lives of thousands of servicemen and the destiny of his country; or the commanding officer of a small squadron; or even an ordinary military pilot fighting in the sky over the Pacific. Gradually, as you play, from all these separate bits and pieces will emerge one impressive picture of the great and fierce battles fought in the Pacific during WWII.
