Earth's Last Hope

The world wasn't the same when they discovered alien-invested mercury. This mercury killed millions and invested others who got too close. Humanoids are what we call them but they call themselves Eath's new hope. They capture and trap survivors to create their kind since they cannot create themselves without us. After the outbreak, survivors hid and trained ourselves to fight against those monsters that changed our world into a battlefield. My name is Zeria and I'm Earth's last hope. My mission: To kill all humanoids.
