The impact from the comet raised a cloud of dust and obscured the sun. All who were on the surface of the earth are now dead. It's now only possible to survive underground. The city has long been dead, and now there are only zombies. But food and weapons remained in the city. Without them, you will not survive underground. Collect weapons and kill zombies.
