Endless Dark Sun

When the sun no longer rises, the world falls into an abyss! Wormholes tear through space, land, and oceans, and countless stinking silhouettes squirm. Humanity's nightmare is those alien beasts that do not belong to this world but can devour everything. They tear apart cities, can easily break through the defense lines of thermal weapons, and even eat flesh and blood as food, but the most deadly thing is the excrement they leave behind! Intense radiation can wither flesh and blood in a matter of seconds, turning the earth into a dead zone. Humanity's last hope is twenty barriers made of titanium alloy. Within the high walls, there is twisted human nature and broken order. Beyond the high wall is the radioactive soil and a hunting ground for strange beasts.
