Armageddon

An asteroid is hurtling towards Earth. Scientists calculate it will hit Coventry and obliterate everything within a 3000 mile radius. Political and military leaders have a plan to avoid global disaster - launch a missile to destroy the asteroid. Unfortunately, an electro-magnetic field surrounding the asteroid has rendered modern digital missile systems useless. The only hope is to break in to the abandoned bunker, get the facility up and running and launch the analog rocket in time!
