Hearts of Iron: Rebuilding Civilization from the End

[Zombie apocalypse, single female protagonist, Hearts of Iron system, farming style] When Heron starships fly across our sky, civilization regresses and the world changes. With aggression from outside and betrayal from within, are our freedom and dignity destined to be destroyed? In times of crisis, Li Jianfeng activated the Iron Ambition System and began the road to rebuilding civilization. Seek aid, develop industry, and build an army. All our efforts are just to go home! When the flame storm from the heavy machine gun position swept through the corpse tide like a scythe. When the steel torrent of the armored cluster crushes the stubborn resistance of the mutant monsters. Like a swarm of fighter jets breaking through the clouds of mutated birds and beasts like sunshine. We will fight in every street, every mountain and river, and every piece of airspace on our home planet. This time! We will never surrender!
