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 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.
