Invasion!
U.F.O.s have been sighted over the countryside! Their intentions are clear - you must stop them before they reach our cities. Fortify the surrounding area with weapons, and stop the hostile alien advance.
Your people are counting on you!
The white dots near the roads are legal positions to build a defensive turret. Each turret costs 50 gold, and you will earn 10 gold for each U.F.O. you destroy. Place wisely!
Enemies will travel along the road. Fortunately, most enemy saucers react poorly to water, and have difficulty passing over natural terrain.
These aliens are crafty and learn from their mistakes. Each wave will be stronger than the last. If 10 saucers make their way into the city, all hope (and your game) is lost!
Each placed turret can be upgraded twice - the first upgrade costs 100 gold, the second costs 200 gold. Upgraded turrets fire faster, fire multiple, stronger projectiles, and have a longer range! A reminder of upgrade cost can be found beneath the game board.
