Infection Bio War is a game that mostly looks, feels and plays just like Plague Inc. The advantage of this game, however, is that it’s free to play, does a really good job at being challenging and addictive and is not plagued by IAPs or ads.
We are here to check out some Infection Bio War cheats: tips, tricks and basically a complete guide for what to do in order to win the game on every difficulty level and then do it over and over again.
This game made it back to the top – strangely – after the rise in popularity of the news regarding the Novel Coronavirus spread in China… but fortunately is completely safe. So let’s dig in and check out some Infection Bio War cheats and tips to win easily!
1. Transmission first, Resistances second
Your main goal is to infect as many people as possible first, without raising the eyebrows of the scientists.
It is completely possible to infect the whole population of the globe without the cure starting – so invest in Transmission traits first. The game can be completely won with only Water and Air transmissions evolved, so don’t invest too much, you will need the points later.
Then, invest in resistances, most important Gene Obfuscation and Natural Complexity. You want the research to go as slow as possible so that your disease has enough time to destroy everything around.
2. Go lethal fast after evolving the first symptom
As soon as you have the entire population infected, evolve the first symptoms (one gets the disease notices, two or more start the cure process). The idea is to start this when you have already some DNA points saved – I would suggest nothing less than 20.
What you should do is to turn your disease into the most lethal one possible as fast as possible, so having 20 points to start with will help a lot.
Start with the Coughing and Perspiration symptoms, as they lead to some highly lethal traits and are relatively cheap.
3. Play the game on easy
Playing the game on Easy makes it, obviously, easier to win. It also helps you unlock most of the Evolutions that give you a ton of bonuses in future games.
So get all the possible evolutions with the game on Easy, and only then move to other difficulty settings, with the extra boosts from Evolutions.
4. What evolutions to use
There are 10 Evolutions and you can only use five. My suggestion would be to use the following: Migrant, Cysts, Foreigners, Lethality Boost and Foreigners (or Reactive, but it’s harder to get).
5. Where to start
Just like in Plague Inc, Madagascar and Greenland are the most difficult countries to infect, so starting in one of them (I’d go for Madagascar) makes it a lot easier.
But in the end, keeping the disease silent and waiting for the whole world to get infected will make any country a good pick for starting the game.
6. Pop those bubbles!
No matter that it’s the red or orange DNA bubbles or the blue ones (research), you should always pop them all in order to get as many DNA points to spend as possible. The more you have, the better your disease and the easier for you to win the game.
Additional strategy by our reader Raul:
If you’re struggling to get past a level although you’ve completed the requirements, you need a high score or complete in hard mode.
I usually start with Egypt, two water traits, two cold traits and first drug resistance, which helps with Europe. That should infect the whole world. Greenland and Poland are the countries you need patience with.
Store around 70-80 DNA points once the world is affected and select the symptoms on the far right and stick to the right side selecting anything that increases your lethality. Aim to reach the top right, tissue breakdown at 27 points. You should win easily after this!
Works on nearly every level. If your meant to use animal traits stick to rats only, they spread quickly, very quickly and mix with water in other levels for speed. Don’t worry about heat and air, rats can infect hot regions easily and blood too.
Additional tips from our reader Scott, regarding infection and lethality:
For those of you who are having trouble and getting defeated after infecting the whole world, I can tell you why… just because you have all the countries in the world infected, it doesn’t mean every single person in those countries is infected.
If you evolve all the symptoms very quickly and the disease is highly lethal, sometimes all the infected people die before the uninfected have time to catch the disease. If you have too high of a lethal to infective ratio, you will always lose because there will be a few survivors who don’t get the disease before all the infected die thus leaving no one left to spread the disease.
The way to prevent that is either wait till every single person in the world is infected or leave out some of the more leathal traits so that the people don’t die as fast before having time to spread the disease.
You can keep track of the rate that people are dying by watching the infection bar. If it turns completely from yellow to red (signifying all the infected have died) before the blue (the uninfected) is completely gone, there will be survivors.
With just a bit of planning and using the tips and tricks that I shared with you above, it will be very easy for you to win at Infection (or Infection Bio War if you prefer the long name) and have fun while doing so. And don’t forget to share with us any other strategies you might have.
Thanks for those pointers, however, how do I get the foreigners evolution trait? Is it asking for me to infect all of the water movements? Because Oceania isn’t a country listed in the game. Thanks for any help!
Well, to be honest, I have no idea how I got that unlocked, but I did. Try starting in Australia or around it… that might count as Oceania.
Does anone know how to win the game in less than 600 days? I tried everything and I just can’t win
Oceania is Australia,new Zealand and New Guinea
I have unlocked Nearly everything… Infecting Africa in 190 days is the problem. I Tried Nearly everything :(
I used Protozoa as my malignant and started with Zimbabwe and focused more on the landborders
Me too, can infect all of Africa but not in time:(
I got Africa no problem. Put points in blood and max it. Then cows Forget the name of the traits. But those are good for rural area and poor area. Then do water and air. After it’s done you have to get Europe in 130 days. Way harder
Did you ever figure this one out? I can’t seem to get Europe infected in time.
I always start in India and win every time and maddagascar and greenland is easy to infect and kill
I did that by starting Madagascar and focusing on border air water and the pill resistance because the second makes the “healthcare” help the disease live. Im stuck on infecting Europe and xenophobia. Cant get any level of xeno.
Hey does any one know how to infect all of Europe in 130 days? Also how do u get the xenophobia achievement??
I’m having the same issue Nicole, I can’t seem to get all of europe in that time and i’ve tried a dozen different ways! Also, no xenophobia achievement no how sure i am of leaving only 5 unpopped
Have you guys managed to get the Reactive evolution? I’ve nailed the requirement a couple of times (win the game within 200 days of the first death), and with ease. I patiently saved my DNA points and waited till the whole world was infected (which took several game years), than set off just about all the symptoms at once. Won the game within 2 game-months of the first death. But it’s still not active. I’ve done this on Easy and Normal, and with most of the disease types. Any thoughts?
Same problem. I won the game within 200 days after first death several times, with bacteria, virus, on easy and normal mode.. İt just won’t unlock. Anyone managed to make it, somehow?
Hey guys,
I can’t figure out how to develop the ports evolution. It says ‘win the game without any fluid (air or water) disease trait’. Does anyone know what trait you can or can’t pick to win this? Obviously i’m restraining from picking water and air transmission traits.
Don’t invest in the Air and Water transmissions. Go for the animal traits instead!
the game is broken. Ive infected Europe within 130 days, usually with 15 to 20 days to spare, several times. The bonus never unlocks. Had problems with other achievements not unlocking too but this one is the most frustrating when I find out it did not unlock after finishing the objective.
How did you infect europe in 130 days!?????
Not to mention the “lab agent” pathogen has a terrible description – who would want to use a pathogen whose cure finished faster? Still not sure what advantage it gives, if it has any.
Finishes*
Oops autocorrect.
The “lab agent” pathogen is given to make the game harder, I think. Its for those looking for a greater challenge
I have unlocked all but xenophobia. Its driving me insane. Ive tried easy normal hard all the diseases. It is referring to the bubbles that pop up on the map correct?
I believe so. But I wasn’t able to unlock that either…
I can’t figure out why my evolutions aren’t working..I put them on the active side but they never effect my game..anyone else have this problem?
For level 10, where i have to infect at least 1 country in every continent in less then 365 days, it says i was defeated.. Even when if i manage to infect EVERYYYY country in the world? Whats going on?
I’m having the same problem with infecting one country in every continent. I keep getting defeated even when the whole world is infected!
i also do not know how to use evolutions, it feels like that app i have is really messed up. I have never seen the option for evolutions. I just learnt about them now by searching about the game online. i am so confused.
This level is impossible! Must be a glitch that will be fixed in a future update, hopefully soon.
Hi everyone!
How the H am i going forward on the Level 20, Infect Africa?
I have tried everything i possible can think of.
Please help anyone ??? :)
I am having the same problem. I get all the countries in Africa infected, but it still says defeated – any tips from anyone at all?
To get the bonus you need to infect all the countries in Africa within the time frame (190 days I think) but the defeat means you lost the game; either the cure reached 100% or you killed all the infected people and still had some healthy people left.
Cold traits? Isn’t it air traits?
I name my infection BieberFever and start at canada and slowly kill everyone
Any tips on infecting Europe in 130 days? I can usually get the northern region done but the UK always holds out till around day 150 or so.
Same here. No matter which strain or starting country or traits chosen, one country (UK, Iceland, or Finland) ends up not infected at 130 days.
I’m new to the game. But, I had to download it 2 times. There are two things that I still can’t understand:
1) International cure research is released fairly fast (even in less than 2 months), without even spending a single DNA point on absolutely anything. Everytime!
2) Even if I win on “Hard”, it won’t open the next levels. (Reason why I erased the app and re-downloaded it)
The genes I have gotten from winning previous levels kind of suck… So, I thought that that, could be the problem. But still…
I do like the game, a lot, but I’m not willing to spend real money into it and it’s frustrating to win everytime and not being able to open new levels. First time, I was stuck on level 6… and it won’t go after 5.
Can someone help? :(
P.S.: I play it on an Ipod 5 iOS 7
at the begin of game where it say tap a place you want to infect , don’t tap a place you want to infect just wait and dna points will rack up and start Upgradeing they won’t know until you infect a place on infection. this will make you win nine times out ten. thank you claus’jr 12 25 2014
How do you win outbreak?
Can someone tell me what country to start in and what evolutions to use to infect all of Europe in 130 days. I have been stuck on this one for ages and just can’t get it done in time. All other achievments completed with relative ease, I just can’t get this one done

Start Sweden
Drug resist
Water
Rats
Cold
Cold2
Water2
Hope for mutations (esp drug 2) and quick land infections
Keep trying. It still takes hundreds of attempts but at least it is possible with the above
I appear to have a glitch, on level 32 red bubbles constantly pop up in mid Africa and Brazil over and over. I could rack up 2000 dna points+ if I could be bothered. Only trouble is those two countries never get infected afterwards. Therefore I can’t move on from this level. Anybody else had this problem?
Need help figuring out how to beat the game in 600 days!
Help! How to infect all and kill the last survivor within 180 days from the 1st death???
hi guys help me .. My disease cant kill pls help
Does anybody know how to infect rich countries with the worm
hey guys, i’m playing the game, and i’m at the level where it’s harder to infect the “rich regions” and i CANNOT get them to get infected… how do you do it?!
I started in Greenland and upped the infectivity and resistances of the disease, but only selected (slowly, not all at once) Nausea, Vomiting, Anaemia, Iron Overload, Coughing, Insomnia and Skin Lesions. It took a while, but I killed everyone with the cure at only 5% (it had gone down from 7%).
How to I win with Synth Spore on Normal?!!? I’m stuck
I need help with the foreigners evolution… where to start, what evolutions and what to point my dna points on. I feel like I’ve tried 300 or so times….
How do I unlock the cheats to the left of easy mode???!?!
