Space Is Dangerous

SID is a combination of castle defense, planetary surface management, and just trying to see how many waves you survive until the inevitable happens.

The main objective is to keep the central base from being destroyed and you place smaller unit bases around the larger central base to act as interference from the incoming barrage of weapons fire from the various enemy ships. Once the central base is destroyed the current game is over. 

Be sure to view the demo release video and the readme file for more.

Note: Progress is not saved in the Alpha demo. We recommend not shutting the game down (EVER) :)
