A challenging strategy game that you can play with tanks. The mission is part of the journey, what system administrator, not the enemy combat vehicles can pass through. This is so you can prevent it by placing tanks along the way. To help you there is also a bomber aircraft, which is rarely true, but you can compare them.
The first time you should do it through education, clearly explaining what to do.
You can use the mouse to play.
Enjoy the game!
