Martian Defense (KoblizekJan, AdamDonut)

You take on a role of a company, that mines rare Martian mineral. The mineral is valuable, but most of the revenue must be used for defense against the Martians.

You start the game with headquarters. Appart from them you can construct 3 other buildings.

Headquarters

provide base for your operation. When it is destroyed you lose the game. Luckily it is equiped with guns so the Martians don't have and easy job ahead of them.

Headquarters also provide the colony with geothermal energy and produce small amount of mineral.

You may improve its energy production and firepower.

Mine

Here you can collect the precious crystal which is the main in game currency. The production rat depends on the amount of mineral in the vicinity of the mine.

Mine can be improved to gather mineral more effectively.

Turret

Deffensive stucture, that should help you to fend off Martian attacks.

Its firepower can be further improved.

Lighting Tower

Provides vision and energy for the more distant parts of the colony. Every building must be placed near the headquarters or one of the Lighting Towers. Otherwise they won't receive energy needed for their operations.
