The Alpha Mining Corporation won a war against it's biggest competitor the Kron corporation for mining rights in Xolora. This planet is full of abundant resources and there has recently been the discovery of a new mineral that can be refined to pure energy. Now the mining colonies are being attacked by a swarm of insect like aliens. In this tower defense game you will need to setup your turrets and charge them with the mining crystals to invoke the most damage to the bug like attackers. The more resources that are mined will allow you to spend more on turrets for your colony defense.
