Chute Defensetower defense
Eliminate the invading force intent on taking Space Station Xorbe in Earth orbit. If the station is captured then it will become a staging ground for the invasion of Earth itself. You have a huge arsenal of weapons and defensive mechanisms at your disposal-use them wisely and you may prevail. All aliens firs point of attack is from the air-so it is important to select, place and upgrade your AIR defenses carefully. If your air defenses fail to block the air assault the aliens will establish beachheads (shaded green) to place their ground towers. At this point or earlier place your ground defence towers to eliminate the aliens before they take too much of your space station.
