This game is win.
It was released in March 2008, but has found its way into the Steam network just a couple of days ago.
So what is the goal in the game?
The goal is to hold out as long as possible while fighting off waves of alien forces. To do this, you build laser turrets. These turrets can focus their lasers on eachother to form an even more powerfull beam. This also increases the range.
You can also build missile turret . Unupgraded missile turret fire plasma missile. The missile turret can be upgraded to fire four projectiles. Upon target contact, the tempest shell explodes, sending out a cloud of electrons generating an electric storm of death and destruction!
The other upgrade upgrades the missile turret to fire 3 seeking missiles with long range.
All this stuff requires power. So you build powerplants. The powerplants produce energy sparks. This spark is the actually power that your buildings need in order to function. To get these energy sparks to your buildings, you build energy links. These move energy sparks and redirects them in the network. Its possible to tell the link where to redirect its energy sparks. Equipped with overcharge-switch. An overcharged link will explode, dealing tremendous amounts of damage to any enemy unit within range.
And finally, there is the harvester. This is just a tower that you place near valuable resources in the form of rock formations, the tower will automatically extract the resources from the rocks within range of the harvester. The extracted resources give you the money that you need to place buildings.
