BGG.CON! BGG.CON SPRING! BGG@SEA!
A summary, from Herb Levy at Gamer's Alliance...
2 to 6 players place their planes on one of the starting areas (marked 1, 2, 3, 4, 5, and 6). The dealer shuffles the Astron cards and deals five of them to each player. The Hazard and Airport cards are shuffled separately and placed in two face down piles. Then, play begins.
The first player plays one of his Astron cards. The Astron cards control the movement of the planes and the map! For example, a card may say "Move Plane 3 back" or "Move Plane 4 Sideways" or "Move Plane 2 back, Move Map Forward Two Spaces". In all cases, the plane moves first and then, if so directed, the map. Now, the player draws another Astron card to replenish his hand, ending his turn, and play passes to the next player.
Planes MUST move in accordance with the orders on the cards played. No plane may land on a space already occupied by a plane or exit off the side of the map. If a player does not have a card that is playable, that player loses his turn and must discard an Astron card and draw another.
On the map, there are 11 Airports, numbered from 1 to 11. There are also 21 Hazard spaces (marked Tornadoes, High Winds etc.) Should a plane land on any of these spaces (whether on his own turn or because of the movement of the map), the player draws a card: an Airport card OR a Hazards card (depending upon which space his plane is on). These cards are only drawn at the end of a turn. So, if a player moves off a space because of the movement of the map, no card is drawn! Airport cards award points to the lucky player. Hazard cards result in points being lost!
Play continues, and the map continues to move, until the words "Game Over' appear at the edge of the playing area. The player on turn completes his turn and then, all points collected are tallied. The player with the highest net score wins!
