Critical Grid — Commodore 64

Critical Grid is a real-time power-routing game for the Commodore 64, written in 6502 assembly. As a reactor technician you steer a probe over the reactor floor, laying conduit from the cores to the terminals that need power. The bigger the live network, the more energy it earns — and the more heat it makes and the more sparks it draws. Sparks leave the vents and hunt for live conduit; a surge fizzes for a second, then burns along the network towards your terminals, so you ground sparks, fit stabilizers and cut the line ahead of the burn. When the heat tops out, every core overloads. Forty grids in five reactor families: Feedwater, Rotor Works with turning junctions, Diode Yard with one-way current, Coolant Basin with hot cores and coolant lanes, and Mirror Core, where every move is copied across the floor. Three stars a grid, family passwords, a records table and an attract demo. Chrome raster logo, hand-drawn industrial tiles tinted per family, an original SID soundtrack. Runs on PAL and NTSC machines; supplied as PRG and a D64 disk image.
