Welcome to the harsh planet of Tarnor. A nearly airless rock circling an ancient Red Giant, the planet is subject to baking heat in the day and freezing colds at night. Despite the unforgiving nature of the planet, the bustling colony of Oasis thrives on the surface as a major trading hub. It's often been said that whatever you need you can find it at Oasis, for a price. However, the colony has...

This is a survival map, where our place is the arena of battle. Our job is to kill the aliens in 1500. The map is quite difficult, you need to cover a good tactic. I wish you good fun.

I'm not that lazy. Online play w...

This map/campaign is in the early stages, and I thought that I should release a public alpha to get some feedback. I intended to have this map harder than normal, where you couldn't really solo this on easy but you could get through it with a team of 2 if you're smart. There's only 1 map in this campaign at the moment, however I'm in the planning stages of the rest and will release these incre...
