Well it is different from D-Day and Bulge in that reinforcements are not predetermined.
It is like those in that it is a small battle and uses Victory Points to determine the winner.
Combat system is with six sided dice but instead of a roll or less value to get a hit each unit contributes a certain number of dice that hit on two or less. Casualties are what I call semi-random. You got a shot at a big unit if the dice come up in the right slot but all of the dice that are two or less will damage something. (In Bulge you can get 5 hits on one unit and leave 4 other units untouched.)
Movement is by unit type. Load and move your transports. Then the other guy. Move BBs. Then the other guy. And so on. Players alternate turns of being first to move their units.
Combat is in phases. Air, naval and land. Units may participate in all three phases each turn if they have an attack value for that phase.
Reinforcements are ‘bought’ at the end of turn based on the islands you control. You have options for fast deployment of units to the front.
It is really very different from Europe, Pacific, Revised. Fun but different.
