There's a terrible darkness that has consumed the world inch by inch. You have to survive this darkened consumed world by lighting the three towers that are located somewhere in die world. Some of the plants and resources have adapted to the darkness and can survive by using the life source in them to emanate light. Use these resources to your advantage and the path to victory will be shown. 

Be warned, the darkness pulls the life out of anything it touches. As time goes by the darkness' powers grows stronger and the light that is being provided by the plants gets less and weaker with the overbearing darkness. It is your job to rid the world of the darkness before it consumes you too. Light those three towers before your time runs out.
