The Division will be updated on Tuesday, November 22nd with the Survival DLC. Survival adds a completely new game mode that pits two dozen players onto the New York City map during a blinding blizzard. As the name implies, they will need to find food, clothing, shelter, medicine all while racing the clock to find a cure for the epidemic crippling the city.
Survival comes in a PvP mode that adds another layer of danger to the game and that allows players to take out other agents. In the PvE version, friendly fire is removed.
For those without the DLC, there is a meaty patch with a number of improvements to the game including a larger stash, a bigger recoil on hip fire and twelve new high end guns and other gear.
