Mutation 1.3

viewable by clicking the show tag

Released July 15, 2012, Change log:

  1. Modify genetic code: The ability to tweak your genetic code prior to playing – this will let you customise your play style (e.g. You can insert a gene which means you don’t need to pop bubbles or one that gives you bonus DNA at the start) Still fine tuning the details but currently, you will unlock a random gene each time you play a game and there will be 25 to collect in total.
  2. The Neurax Worm – this is a terrifying new Plague type which will require all new tactics to win. I’m really excited about this as I have basically redesigned the gameplay from scratch. It will have new graphics, new events, new victory conditions and a very different playstyle. (I view this as a mini expansion pack so it will cost 99c to play with this plague)

Mutation 1.7

viewable by clicking the show tag

Released November 25, 2013, Change log: Scenarios significantly increase the amount of content for players – giving them new challenges and experiences which will test their skills to the limit. There are two main types of scenario:

  • Real life diseases – begin the game with fully evolved, real life pathogens like the Black Death, Swine flu or HIV. Players can model how an outbreak would happen in real life as well as mutating the pathogen to try and get it to infect the whole world.
  • Alternative universes – choose a pathogen to infect a world that has been impacted by something like a US Debt default, an outbreak of xenophobia or a new mini ice age. Players can see how different events can shape the ability of the world to respond to global pandemics and work out how to best exploit the new conditions.

Example scenarios:

  • Sovereign Default: A failure to extend the debt ceiling in the US triggers a major financial crisis - causing significant economic damage and reducing the wealth of countries all over the world.
  • Black Death: Patient Zero is infected with a previously dormant strain of Yersinia pestis. Humanity must face a bacterium that has been hidden for centuries - previously killing over 200 million people.
  • Xenophobia: A rapid increase in hostility towards foreigners causes all countries to heavily fortify their land borders - significantly reducing the amount of cross border land traffic worldwide.

Release date and price:

  • November (iOS) November/December(Android)
  • There will be 15 scenarios on release with more to come in future updates.

2* scenarios will be free. An individual scenario will cost $0.99 or “All Scenarios” can be brought together for $2.99. Buying “All Scenarios” will also include all scenarios that are released in the future
