Shopping District image - The Ark Mod for Half-Life 2

A zombie apoylypse mod that spans several centuries. In the year 1543, the government learns of the impending zombie apocalypse. The earth has an expiration date, and in a little over a hundred years, the dead will walk the earth in the millions, sending it into chaos. The gates of hell will open, flooding the earth with all sorts of horrors (think Silent Hill.) The government realizes that the knowledge is too dangerous and could cause a world wide panic, so they conspire to keep it under wraps. They decide to begin constructing an enormous ark to evacuate as many people as they can on the day all hell breaks loose. Basically, Hellboy + 2012+ George Romero Movie + Doom 3
