The Last Shelter

We did not start this war ... But we must protect our mother earth from alien invaders. The climate on earth has changed and only a small piece of land remains, which gives humanity hope for survival. All the streets of the city have become ruins, and those houses that are still standing have long been plundered. There is practically no food or water, and a small group of survivors are forced to hide and fight for their lives every day. But the aliens have other intentions, humanity must be destroyed on this planet! Buy weapons, set up a line of defense and defeat the enemy!
