Evolution 20 - Multiplayer balance update

Hey everyone

We have just released a new multiplayer balance update for Plague Inc: Evolved which addresses some of the feedback we have been getting from players. Fans of viruses and parasite will be particularly excited by this!

  • Parasite tweak - Parasitic DNA theft buffed - parasite now steals 45% of opponent's DNA, up from 40%. Remember, your severity will increase as your opponent evolves so it won't be long before humans are out to cure you!
  • Virus tweak - We found that the virus was devolving too often to get much use in competitive play. We have reduced the chance of devolving to 12% (from 14%) and also made it 5% harder to cure
  • Bioweapon tweak - Bioweapon continues to be one of the more popular disease types in VS mode - we are making it 5% easier to cure to prevent it becoming too dominant.
  • Benign Mimic tweak - One of the most popular active abilities in VS mode - we are making a few changes to its duration and impact to ensure that other strategies have enough room to breathe. Will keep an eye on this and see if more action is needed.

We are hard at work on a new disease type for Plague Inc. at the moment - will share more information on it soon!

Also - it is still possible to make a late pledge for Plague Inc: The Board Game here:

Full Change Log:

MP VS mode balance changes
  • Bioweapon ~5% easier to cure
  • Virus ~5% harder to cure
  • Virus devolve chance now reduced to 12% from 14%
  • Parasite now steals 45% of DNA, up from 40%
  • Benign Mimic lasts 5 days longer
  • Benign Mimic starts slower and increases in strength over time
  • Daily cure impact of an individual benign mimic now capped (at ~5% of total cure requirement)
  • If immune shock used in a country without opponent - has lesser impact on infectivity
Bug fix
  • Fixed Edge case on publish for Scenario Creator
  • Minor Load/Save Fix
  • Fix for edge case of unlocking Official Scenarios

About This Game

Plague Inc: Evolved is a unique mix of high strategy and terrifyingly realistic simulation. Your pathogen has just infected 'Patient Zero' - now you must bring about the end of human history by evolving a deadly, global Plague whilst adapting against everything humanity can do to defend itself.

Plague Inc. is so realistic that the CDC even asked the developer to come and speak about the infection models in the game!

Over 65 million players have been infected by Plague Inc. already. Now, Plague Inc: Evolved combines the original critically acclaimed gameplay with significant, all-new features for PC including multiplayer, user-generated content support, improved graphics and lots more.

  • 10 Different Disease Types – Master every pathogen; from bacteria to bio-weapons and mind control to zombies, end humanity by any means possible – different diseases will need radically different approaches.
  • 20 Unique Scenarios – Adapt your strategy; scenarios create further challenges for your pandemic – how will you handle a new strain of Swine Flu, or infect a world in Ice Age?
  • Hyper-Realistic World – Strategize in the real world; advanced AI and use of real-world data and events make Plague Inc: Evolved a highly authentic simulation of a world-ending pathogen. Even the CDC likes it!
  • Competitive Multiplayer - The world is unlucky enough to be infected with two plagues, but how will you win the battle for genetic dominance against your opponent? Players get all new evolutions, abilities and genes to help them fight for global control and destroy their opponent!
  • Co-Operative Mode - Two different diseases team up to infect and destroy the world together but Humanity has new tricks up its sleeve to fight back! Work closely with your partner and use brand-new genes, traits and strategies to smash cure labs all over the world before they eradicate you.
  • Contagious Content Creator - Hit the lab and develop your own custom scenarios - creating new plague types, worlds and in-game events. Sophisticated tools support user-generated content to let players bring their deadliest ideas to life and share them on Steam Workshop. With over 10,000 custom scenarios already released - there is always something new to infect!
  • Blinding Graphics - Full 3D disease models take you closer to your plague than ever before, city-cams show humanity's struggle at street level, and the body scanner highlights the full effect of your mutations, organ by organ.
  • Deadly Data - Geek out with stats and graphs; monitor infection and death levels, track government reactions and cure efforts, then review your plague's success (or failure!) with full game replays.
  • And much more... - Including speed runs, Mega-Brutal difficulty and genetic modification... Plus loads of new disease types and scenarios in future (free!) updates.

It's the kind of game that when someone walks in on you, you switch to porn becuase it's easier to explain.

10/10 would get mistaken for a terrorist again.

That's... boy, I wish that was just a joke.

That being said, this game requries a lot more strategy than you think. When you first start out, you probably think stealth is the best way to go, until you hit Brutal and your only option is to go hard or get cured. Pretty much every plague type has a mechanic that requires tweaking your strategy, to the point where if you play blind, you have to play several games just to understand what kind of angle you need.

If you're coming from the mobile version, as I did, I would definitely recommend this version. It's not a direct port, more of an upgrade that breathes a little life into a game all about murdering everyone on the planet. Now, I haven't played it as extensively as the mobile version (I bought it on release to support the dev and never played it until recently WHOOPS), but just playing a few Co-op rounds with a friend has definitely made this worth it, and the added Workshop functionality means more screaming for everyone. And, IIRC, all updates are free.

  • Great bubblewrap simulator.
  • Beating Mega Brutal with bacteria and almost no genes feels really nice, okay.
  • It makes you feel really smart with all these big fancy words wow look at them all.
  • Easy to alt-tab out of, for all your alt-tabbing needs. Probably to look at a guide and cry. No judging here, man. That Necroa virus sure is killer. (Yes, you can hang me now. I've made enough bad jokes.)
  • The news reel and random events are kind of great. The game has just the right amount of humour for being a game about pathogens.
  • It just has such a nice draw to it. Makes you feel like a mad scientist kicking back and watching the world burn. (Sometimes literally. What is with these nukes, mate.) A+ ego boost.

  • Greenland.
  • I'm probably on a watchlist now somewhere, tbh.
  • Being able to infect everyone after you get noticed didn't really feel right until I remembered standard precautions even in 'rich' countries is actually really poor because no one follows them as rigorously as they should. Not really a con about the game, just a little bit of an unsettling revelation.
  • Greenland.
  • Sometimes when you make a mistake, but still obviously going to win (ie, no cure prgoress being made), it takes forever for the game to finish. I've only really noticed this with the Necroa virus because of the zombie mechanic (I'm a scrub I know I know), so it isn't something that happens often, but it's my only real complaint.
  • Maybe it's just because I'm playing on a glorified toaster, but the Steam overlay keeps glitching out and closing on me. I'm going to do some testing on this one as soon as I can. This isn't a game breaker, though.
  • Greenland.

So go get it. Be the change you want to see in the world. And for the love of God, evolve water transmission and cold resistance.

I thought that this game would get bored after a while, but I was so wrong. It is so much fun to play! The workshop is a great thing in this game, because there are made many cool plagues. The multiplayer is awesome too! I strongly recommend this game.

Definetly reccommend this to others. The whole game may seem like a template world map with just watching red dots popup, its much more than that with stratergy, the diversity of each disese, and a full working steam workshop. Only downside imo is the only 3 diseses simian flu, necroa and neurax have different symptom transmission and ability layouts which what makes them stand out amongst the others, but that doesn't stop me from enjoying this game, 9/10 from me. Keep up the goodwork Ndemic!

Plague Inc Evolved is a strategy game about creating and evolving a disease that will infect and ultimately destroy the whole world. Upon discovering your disease, scientists of the world will attempt to cure it.


Great things:

-This is the biggest pro in my opinion: there is something for everyone here. It is a great casual experience for people who aren't big strategy gamers. My friend who claims to dislike "map games" loves this game. Hardcore strategy gamers and fans of the genre will also find fun here. I, for example, play tons of 4X and grand strategy games, and I love this one as well. The harder difficulties and scenarios (custom and official) can provide great challenges and interesting strategical situations.

-Fantastic difficulty curve. The game is very easy to learn, and provides a fun challenge to master it at the hardest difficulties. The jump from Brutal to Mega Brutal is pretty big, but that gap can be filled by harder plagues or scenarios. The game never has to feel too easy or too difficult.

Good things:

-Good variety with the main plagues, official scenarios and custom scenarios. I will say that the "normal" plagues (bacteria, fungus, parasite, and prion) all feel very similar to each other, but even with that in mind, there is still a good amount of variety in the main game. Some of the official scenarios are very interesting, and can provide a large or small shake-up to your normal strategy. However, I will say a large portion of the scenarios don't feel all that different from the main game or each other, which is why I put this under "good things" instead of "great things." But there are so many scenarios, you will definitely find something interesting.

-Custom scenarios are great. The game allows community members to create their own scenarios and customize the world, events, and the plague itself to create a unique experience. When you start to get a bit bored of the normal stuff, there are basically ENDLESS custom scenarios to play. True, not ALL custom scenarios are good, but custom scenarios are produced so often, that is is viable to only have to play really good ones. And the editor is very intuitive and explains everything very well, so it easy and quite to fun to create your own custom scenario. I rank this as "good" instead of "great" because the editor doesn't provide THAT much variety, and (last time I checked) TRULY unique plagues like the Necroa virus and the Neurax worm, cannot be created in the editor. Granted, they would be difficult to create, but many communities have dedicated creators who put time and effort into creating cool content for the game, and I have no reason to believe this one is any different. Anyway, you may feel that none or few of the custom scenarios feel meaningfully different from anything else.

-Clean and intuitive UI. You will never be befuddled by this game's UI. It is not over-complicated, while still providing all the information you might ever want. As well, it looks very nice, and has some nice aesthetic but not distracting touches, such as a cool picture of your pathogen, and what an infected body might look like.

-Concept: It is a very cool and interesting concept to manufacture a plague to infect and kill the whole world. The only other game I know of that has a similar concept is Pandemic, but Plague Inc has much more depth I would say.

-Sound effects are pretty cool and fit the theme of the game rather well. There are enough to feel satisfying, but not so many that you get annoyed.

Okay things:

-Main graphics on the map are pretty good, if simple. You can zoom in quite far and see some detail. However, you would never want to do this, as there is never a reason to not look at the whole map, as you might miss something, so you might get a little tired of looking at the same thing all the time (besides the UI screens), although admittedly it is satifying to see everything slowly turn red!

-Music is a bit lacking, but not bad. The main "music" creates the feel the game is going for, and is mostly ambient noises. I'm not sure if actual music would fit this game well, but nevertheless, I cannot rate the sound here as "good." It is a short loop, and there is not much to it, but since it is just ambient, it won't annoy you, I wouldn't recommend muting it.

-Multiplayer is pretty meh. There are two multiplayer modes: Co-op and competitive, which I really like. They are pretty different, so I will start with Co-op.
-Co-op mode involves two players controlling separate plagues on the same map, and they can work on separate regions, or the same, and they can buff each other. However, multiplayer seems to function very differently than singleplayer with changed mechanics, and yet the game doesn't seem to tell you this, so we floundered a lot in this mode, despite both being very good at the singleplayer modes. Even when we won, most of the time, one of the plagues got eliminated early on and the other one did all the work. Also, pop-ups don't seem to appear as much in multiplayer, so I had my plague 50% cured without even noticing that the cure started.
-Competitive is fine, but it feels like a race, like we might as well just play singleplayer and see who wins first. Interactions are limited to several evolutions that can "sabotage" the other player. Some of these are very major and can change the whole game, but usually the other player will just do the same to you, as they are pretty much forced to, so it still feels like a race, just under different conditions. Also, the victory conditions are changed a bit: you don't have to kill everyone, just infect everyone, which is a big negative for me, as it feels like half the game is just missing. You can also win if the other plague is eliminated. As mentioned, you can sabotage the other player, but this victory condition almost always feels like you won because the other player messed up, and not because you did well, so can be a bit unsatisfying. I have mostly mentioned negative things, but that's not to say that multiplayer isn't fun. It is still Plague Inc, and all the previously mentioned positives still apply, it just isn't quite as fun as the singleplayer mode for me. However, big disclaimer: I don't have many friends who play this game, so I haven't actually played that many multiplayer games, so my opinion on them might improve as I come to understand them a bit better.

Bad Things:

-This game's only real con is that it can get a bit repetitive, but that can be a big con.
-The game lacks any real variety in its events, and doesn't have that many to start with, so there is very little variety created by in-game events, and even the ones that do happen seem to barely affect anything in the game.
-For many of the plagues, the EXACT same strategy can be used, and it can feel very repetitive. However, this isn't a huge con, as many of the more unique plagues and scenarios can change it up quite a bit, but it will still feel prevalent as you try out different things.

-This is sort of a subset of the repetitiveness, but it is the biggest issue for me: Most of the symptoms feel the same. There are many symptoms in the game, but for most plagues, they consist of: Increases infection rate, increase death rate, or slow down cure research. Different tiers of symptoms will do this at different levels, but still feel the same. It can be fun to think about how people are affected by the actual symptoms you are adding, but from an actual gameplay perspective, many feel exactly the same.

OVERALL RATING: 8/10 - Worth buying at full price.

The pros heavily outweigh the cons, and you will definitely get some fun from this game.

This review went way longer than I intended, but hopefully it was helpful to you!

Can you infect the world?

Plague Inc is a unique sandbox/strategy/simulation game in which you'll be able to play up to 8 different types of deadly diseases with one main goal: To infect and kill every single person in the world. Sounds morbid? Well, it surely is!

Upon launching a match you'll first get to choose the disease you want to play - you'll also get to choose one of four difficulty levels - the least one being really though - even for long term players. After this you'll skip to a map of the earth and here you'll get to choose a starting country and from there on you gotta use the skill system (3 skill trees which differ - depending on your disease - all of them using DNA which you'll gather during the match) to overcome the obstacles which the game will throw at you. You'll develop more efficient transmission/resistance abilities to spread further and infect more people - as well as symptoms to spread and later to kill. The setup is very realistic, with a ton of countries, climate zones and random events to make every match you play unique. Note that every match is 45 minutes to 2h long - depending on how you're playing. You're able to save and revisit your match at any given point.

At first you'll only able to play as bacteria but upon winning a match you'll unlock the next disease-type. You'll also unlock genes to modify your diseases to make them more resistant to their environment and to generally strengthen them (this enables possibilities to differ in strategies and YES, there IS a zombie disease ).

I should mention that there aren't any graphics aside of the skilltrees and the map on which planes and ships are moving around and infection bubbles popping up - but those are enough to make it an entangling and fun game. The soundtrack is very good - and there are sometimes sligth noises like coughing or children playing depending on which far your disease has spread. In the end everything is silent - a pretty sinister and strong impression if you'd ask me!

I should also mention that there is a enjoyable multiplayer with PvP and Co-op and a scenario creator as well as tons of archievements and scenarios - most of them for more experienced players!

This game is extremely fun despite having such a scary background and I really recommend it to you if you're interested in diseases and tactical simulations with much freedom and many ways to approach your goal!

It's so much fun playing this even when I fail. It gives me good ideas for stories to write when I'm not playing. It'd be great if the scenario editor allowed players to customize borders or even offer a fractal generator so players can create different lands to try and infect while also allowing people to create different countries and customize wealth and climate in addition to the scenario editor. I think the game would sell even more if the devs considered this approach, even though the game is already highly successful as it is. Either way, this is a great game to pass time. I highly recommend.
