StarCraft: Doomsday Dominion

A month into his first job after graduation, Lin Chen receives a mysterious electronic watch and becomes bound to the StarCraft Terran System. He learns that the apocalypse will arrive in 30 days. The System can produce units and store supplies, but its units need crystal cores to remain operational, and its dimensional space can hold only supplies and units. Lin Chen maxes out online loans, sells his house and car, borrows from every friend and relative he can, and raises funds to buy supplies in a frenzy. Taking advantage of his foreknowledge, he tracks reports of unusual biting incidents, sneaks into quarantined zones to hunt early zombies and collect crystal cores, produces SCVs and Marines, and dispatches units around the globe to gather supplies from docks and warehouses.
