You are the commander of a lonely outpost in a savage battle for the last deposits of minerals. Cling to life any way you can and help your faction dominate.

All is quiet, nestled on a rock, until you spy an upstart enemy fort in the distance. Suspend a bridge above a ravine to open new mines, speeding the expansion of the fort. You’ll need to meet the threat with force. Your fort grows vertically with timber and armor to reach the wind and gain height advantage. Turbines are built to add to the reactor’s power generation, making sure the wind isn’t blocked.

The enemy opens fire so a sniper nest goes in. Doors open and you snipe the offending mini-gun. A workshop allows you to unleash mortars from above, but the enemy picks them out of the air! Upgrading to an armor piercing sniper clears the way and you set the enemy on fire. They repair the damage and respond with a swarm of missiles, destroying your sniper and breaking a part of the fort – it rocks under the weight.

You gather yourself and after expanding resource storage, build a new factory; it’s time to get serious. The enemy beats you to it with a devastating laser, but only glances the foot of the fort, causing a small fire. Finally the cannon is ready – can you bring their fort to the ground?
