Whether you're a noob or a pro, Plague Inc. has a difficulty perfect for you.

Plague Inc. offers a few different difficulties so that players who have passed one level can continue challenging themselves. The difficulties are casual, normal, brutal, and mega brutal. Although there may only be four tiers, each tier is unique, and this guide will explain how.

1. Casual

Casual is the first difficutly you must defeat in order to prove your worth.

Casual is the first difficulty you must pass in order to advance. Although beating Casual won’t let you move on to the next plague, it will allow you to unlock genes that can be used in future plays

How Casual Works:

People don’t wash hands
Doctors are slackers
Sick people give hugs

Casual Details:

Can be replayed to unlock different genes
Easiest difficulty
Finishes relatively quickly

2. Normal

Normal is a great level for players looking for a light challenge.

After you have proved your worth and beat Casual into the dust, then the next difficulty that awaits is Normal. To unlock a plague you must first beat the previous one on Normal.

How Normal Works:

About ⅔ of people wash their wands
Doctors work 3 days per week
The sick are ignored

Normal Details:

Must be beaten to unlock next plague
Standard difficulty
Decently challenging

3. Brutal

Sometimes to win Brutal you'll need a little bit of luck.

Before Mega Brutal came along to take the title, brutal was the hardest difficulty of Plague Inc. Don’t underestimate Brutal though, for it is still a challenge even for experienced gamers.

How Brutal Works:

People wash their hands compulsively
Doctors work 24/7
Sick people are imprisoned

Brutal Details:

If you beat all standard plagues on brutal you can unlock a special plague
Beating a plague on brutal will also unlock the next standard plague (if it hasn’t been unlocked already)
Extremely difficult

4. Mega Brutal

Even pros have to play Mega Brutal levels multiple times in order to win.

Mega Brutal is the most challenging of them all and is the cause of many a strategy guide made by expert Plague Inc. strategists to help out their fellow gamer. Plague Inc. goes as far as to describe Mega Brutal as, “For players who thought Brutal was Casual.”

How Mega Brutal Works:

Evolution impacted by genetic drift (the more who are infected, the more symptoms cost)
Doctors invest in research
Citizens receive random medical checks
Plague is automatically discovered once a country has been completely infected
