Plague Inc.

The folks behind disaster game Plague Inc. — your job is to infect and kill everyone on Earth — today have let loose a preview of what we can expect in the upcoming Mutation 1.7 in a couple months.

First is the addition of "real-life" diseases. You'll be working with the Black Death, Swine flu, HIV or the Bieberic Plague. (OK, we might have made up that last one.) Then there's the new "alternative universes," where such real-life scenarios as the U.S. defaulting on its debts, or xenophobia or an ice age will affect gameplay.

There also will be new achievements, and the requisite bugfixes. You'll get 15 scenarios initially, two of which are free. The rest cost 99 cents each, or you can snag them all for $2.99.

Look for Mutation 1.7 in late November or early December, Ndemic says.
