(intense music) (static crackles) (heartbeat beeps) (logo sizzles) Plague Inc: Evolved. I've never played the original Plague Inc, but I've seen a lot of requests for this and this is actually a really popular video game. For players wanting a quick game. No one washes their hands, researchers, doctors don't work, sick people give hugs. Normal, 67.3% of people wash their hands, doctors work three days a week, sick people ignored. Brutal, compulsive hand washing, doctors never go home, sick people locked in prison. Mega Brutal, genetic drift impacts evolution, doctors invest in research, random medical checkups. I guess, let's do Casual just to get a quick game, to learn how this bad boy works. Name your plague, DM-V4. (laughs) I dunno why V4 but now it sounds scary. All right, you are a new bacteria. To win you must evolve and spread across the world, wiping out all humans in the ultimate plague. Select start location. Select a country to begin your plague. When you select it with the R2 button, you can see more information. Pop the start bubble with R2 to confirm, or select another country instead. Use the left stick to move the crosshair. Okay, world population 7.1 billion. Where should we start this? I feel like I don't want the plague to kill anyone on the North-East coast of the United States, so I won't start there. You know what? Lets target the motherland. (laughs) Russia, population 160 million, there is planes, there's ships, it's rainy, it's snowy, lots of leaves. DM-V4 has infected its first human. Weak but used to cold temperatures, it must evolve using DNA points to infect more people. I've infected one person with zero dead. There's airplanes flying all around. Okay, if I do Blood 1, gives organism ability to spread to blood-to-blood contact. Water 1, pathogen can survive outside in fresh, warm water. That's definitely not good for Russia cause there's no warm water. Air 1 gives pathogen ability to travel on dust particles. Common flea, no we don't want rodents. Birds, insects, I say blood through blood contact, that's probably the best for Russia. Oh, symptoms. Painful cysts containing pockets of the pathogen, slight chance of bursting which can spread disease. And that costs two DNA points, I currently have three, let's evolve. Woo, look at that evolving happening! You have spent DNA points to evolve your disease and more options have opened up. Get more points by popping DNA and Biohazard bubbles with R2 and infecting people. I don't get-- Oh, I popped. Oh, I just got DNA points! Okay, time to make this a bloodborne pathogen. Yeah! Oh, this is gonna be bad. Okay, DM-4 has infected hundreds of Russia, increasing the chance that a infected person will infect a healthy person. Keep evolving your disease, cool. See, I wanna go for Blood 2 because then we can infect bodily fluids and get mucus membranes going. It's gonna be like the flu. We're gonna make DM-V4 like the flu but with cysts. This is really weird. Ooh, I like this. If they can get an abcess, pockets of infected flesh are painful and act as breeding grounds for the pathogen, increasing infection sites, yeah. Ooh, we got abilities. Pathogen evolves, yes! We need cold resistance, 'cause in Russia, it's freezing, trust me on this. I've never thought I would be so excited about infecting the world. DM-V4 has infected thousands in Russia. People are being infected faster and faster, yeah. 22,000, 23,000, okay. Oop, medicine in Norway slowing infection. Norway's a wealthy country with high quality health care. To spread faster, you may need to evolve the drug resistance ability. Norway, you got good health care but I'm coming. DM-V4 is beginning to spread around the world. Hit the Triangle button to see which countries are infected. Wow, look at that, we got Norway, Finland, Russia, Ukraine, Turkey, Iran, Kazakhstan, China. I'm gonna create drug resistance to make sure Norway doesn't start catching up to me. I already got 2,000,000 infected. DM-V4 has infected more people in the world than TB. It is a very infectious disease. My god, look at the country being wiped out. 21,000,000 people, two dead. I've claimed my first victim. This is making me happy for a really strange reason. Russia is the first to instruct doctors to begin research into a cure for DM-V4. The more scary DM-V4 becomes by hurting and killing people, the harder humans will try and cure it. Remember this when evolving your disease. Oh, no, we have a million dead as a result of my illness. Russia exterminates pigeons, what? What's happening in Russia here? Oh my god, look at the government is dispensing bottled water, exterminating rats, face masks are being distributed, exterminating pigeons, what do the pigeons do? My god, Russia's dropped already $2,000 on medical research. That's not that much money, Russia, you could do better. Oop, oop we got a case in the US! Do we have a case in the US? Oop, 17 infected. All right, poor Russia is just all red on this map. Greenland is about to wiped out. Am I gonna destroy the population of Russia right now? 90% of their population's infected. 10% of their population's dead. All hospitals are closed, they're using mass graves. Jesus. Oh, it's spreading into Africa and Australia. Okay, I think I'm taking over. I think the world's about to end. Killed more than the Black Plague. We've killed over 75,000,000 people. Tip: Fight the Cure. There are two ways to fight development of the cure. Evolve aggressive symptoms to destroy countries, more noticeable, or evolve cure resistance, less noticeable. (gasps) The cure in the US for DM-V4 is 25% complete. No way. (gasps) Research doctors all over the world are completely focused on developing a cure. No. Indonesia is leading the global cure effort. They started to send research teams. Pop blue bubbles to destroy their research. Stop doing research. They may find a cure. This might be problematic. 'Cause I think I infected all the countries and I think I was too aggressive with it. Oh, the cure of the world is 70% done. You know what I need to do? I need to create warm resistance so it can spread to Africa. Let's see if I can get it to spread to Africa. The cure is 95% complete. I've only killed 362,000,000 people. The cure for DM-V4 is finished and it's being deployed worldwide. Oh no, look at the number of infected. The world has survived a devastating plague and will soon eradicate DM-V4 forever. Large numbers of people have died and the world is changed forever. No, this is so sad. No one's officially infected. DM-V4 has been eradicated.
