Plague Inc., by Ndemic Creations, has discovered an all new mutation: Santa's Little Helper. A new update adds a new Christmas scenario where you infect the world with the holiday spirit. Governments have banned the joyous holiday and it is up to the Neurax Worm and Santa to bring the world to its knees with happiness.
The update brings some upgrades, too. Using highly advanced technology you can now teleport to other countries using portal. The progress screen has also gotten a bit of a redesign so now you can see your completion % and challenges. Several diseases, including Parasite, Prion, and the Neurax Worm, have mutated and the humans are getting smarter so the game will now be a bit more of a challenge.
There is so much to to explore - just try not to catch the flu while you do. You can check out the cheerful new Plague Inc. for $0.99.
