Trama
A strange rain engulfs the city, unleashing infected creatures and collapsing civilization overnight. Daniel Walker, an adopted son betrayed by his family in his past life, once gave everything—only to be cast aside and left to die. Now reborn at the start of the apocalypse, he awakens Apocalypse Squad System. He upgrades his war vehicle, gathers supplies, and builds his own force as he prepares for survival.
