Coral Sea is a variant expansion to the Midway war game. Each player has his own map of the Pacific far west of Midway, near Indonesia and the Philippines behind a screen. They search for the enemy fleet by moving search planes to the hex and calling the hex number. Once found, bombers can be sent in to sink the enemy fleet. The actual attack is fought on a separate battle board where the ships are first placed on hexes and the attacking planes are placed in hexes to indicate which ship it is attacking. Note: the rules and maps for the Coral Sea Variant were published in General Magazine Vol. 15, #5, counters were available separately via ordering through Avalon Hill.
