The good days are over. The creeps are determined to prepare a campaign against the human race. We're facing extinction if we don't do something about it. That's where you come in. Prepare your defense against the oncoming waves of creeps. Good luck!
Defend your fortress from the oncoming enemy waves. Place turrets in locations of your choice on your fortress, creating the best defense possible to withhold even the greatest of attacks.
Defend against the robo-bugs that are trying to take over your base. Unlock and upgrade new areas and special weapons. Collect enough exp points to get more powerful weapons.
Eliminate the invading force intent on taking Space Station Xorbe in Earth's orbit. If the station is captured then it'll become a staging ground for the invasion of Earth itself. You got a huge arsenal of weapons and defensive mechanisms to stop them.
Dino hunters have teleported a cache of dinosaur eggs in their time-traveling RV. Now the enemies are in hot pursuit. Set up your defenses to protect the Dino Hunters' RV and keep the egg snatchers at bay.
The aliens are back to snack on farmer brains. This time they are filled with ACID BLOOD! Look out, the acid will harm your defenses. Strategically place the crop circles to make the maze then set up your defenses and blast the aliens back to outer space.
To Protect the Earth from alien invasion, you're given a ship class AT-021. But unfortunately the Earth doesn't have enough resources to supply new arms to the ship. Improve the ship by collecting weapons through battles and buy turrets to defend.
