Box has been opened, but the game is new in the box. Never played, never punched. In excellent condition.
Description from Board Game Geek:
Avalon Hills epic German airborne attack game.
Air Assault on Crete features a bonus game, Invasion of Malta--1942, and a third game, if you count the variant from The General magazine, Volume 18, #3, Assault on Cyprus. Each game includes its own mapboard and counters and shares only a minimum of components with the other, however, they share the same basic rules system.
A strategic battalion level game, Air Assault On Crete simulates the first totally airborne invasion in history, with the Germans overwhelming the rag-tag Allied survivors of the ill-fated Greek Campaign.
Traditional turn sequencing: Axis bombard, move, combat; then Allied movement and combat. Units have attack, defense, and movement values, as well as stacking limits. Standard terrain effects. Zones of control, but theres no mandatory attacks.
