A realtime strategy game. This also includes the games Exodus, Ankh, Botkiller 1 and 2.

TEK (aka TEK 1608) is a command and conquer style game. The basic idea is that there has been a Nuclear war and the drug to help people survive has been pinched by another company - and so the corporate wars begin.
You are able to build weapons, set up cameras to ensure your base is monitored, carry out raids, repair vehicles watch the fog and mists roll by. One interesting thing is that as long as you have money (credits) and a production plant, the game is never over; you can even produce your own men.
