xbox game where no food no water and have to you survive

The hordes of zombies are gathering as the US Government announces that it’s no longer capable of paying its debts. The dollar is heading straight down in value. Panicked, soon to be zombies rush to their local banks to get money while it’s still worth something. Banks close their doors as they run out of cash to cover withdrawals. Food distribution comes grinding to a halt as stores run out of the 2-day supply they have on hand. Gasoline goes to 6 dollars a gallon as supplies disappear. People flee the city in huge herds, mindlessly seeking any kind of safety. Within twenty four hours, the police are overwhelmed as the battles begin in the streets.
