One more of these threads, yes.
Ever since I got my new phone I've had a reason to toy around with it a bit more than I normally would.
It's not one of the newest phones, but it sure beats the fuck out of my old phone.

Well. Here goes.

I'm going to recommend you a game that is essentially the same as Pandemic (If any of you played it online)
And the goal of the game is to wipe out the human race with your Engineered disease (To a limit)
While doing that, you have to make sure it spreads to EVERY individual so that you can kill off the entire human race.

So you have to be crafty in how you're spreading it, where you start it and what symptoms it has.
Because, the more the symptoms, the higher the chance to get discovered and ultimately cured (vaccine)

It's very addictive I must say, I've spent several hours playing it.
If it's allowed - I'll post the "cracked" version for Android. Can't remember if it's prohibited or not.

TRY IT!
