Last Night on Earth 'Darkest Night' Scenario

From Flying Frog's website: Trapped and alone in the Radio Station atop Timber Peak, Samantha the DJ has broadcast for help as the Zombies close in. The only thing keeping them at bay is a thin net of arcing electrical wires she has set up surrounding the building, powered by a pair of old generators. Sputtering as their fuel runs low and the lights flicker, it is clearly only a matter of time before the generators give out. Her only hope is that someone will hear the sound of her voice before it's too late.
