After a timeline shift has made acid rain deadlier and accelerated zombie mutations, the protagonist learns from Freya that prolonged rain exposure strengthens zombies, risking second mutations. Determined to prevent further danger, he activates his turret and kills a zombie attacking his window. This victory unlocks a seed shop in his Pocket Dimension Farm, where he chooses offensive crops to boost his combat power. His RV transforms into a special crop farm, allowing him to cultivate evolved blaster chilies and organize his farm into vegetable, fruit, and corn zones. Just as he settles in, a suspicious government message arrives, hinting at new threats ahead.
