Tom Clancy's The Division Jumpchain

From the introduction:

Happy New Year! Welcome to New York! This world is not unlike your own, but with one… major difference. 90% of the human population has been wiped out by a genetically engineered virus known as the Green Poison. New York was ground zero, and the island of Manhattan has become a quarantine zone. To contain the many threats present on the island, the US government has activated what is known as Directive 51, resulting in the activation of a secret group of sleeper agents known as The Division. This first wave is almost completely gone, and the second wave is only just being activated.
