Multiplayer is a mode, in which it allows players to compete with other players. In multiplayer, there are two modes available, the Versus Mode added in December 2015 and the Co-Op Mode added in February 2016.
The multiplayer mode adds special abilities, symptoms and transmissions, which will help players gain more infectivity, severity, lethality or resistance to the cure. It also adds particular genes that help the plague adapt better in certain environments.
VS Mode is a game mode introduced in Evolution 15 for Plague Inc: Evolved released at the end of 2015, which consists of two players competing against each other to see which plague will dominate and end the world.
Co-op mode
This mode is where your two plagues work together to wipe out humanity. If one of your plagues do, then you will both win.
Gameplay
In Co-op mode, two players work together to wipe out humanity. Gameplay has been heavily altered from the main game like in Vs. Mode but with several differences. The player's plague is colored red while the partner's plague is coloured yellow. The population infected by both plagues is orange. The goal is the same for both players.
There are genes exclusive to multiplayer like in Vs, however, they have to be unlocked separately rather than being carried over from VS.
Victory
When both players managed to wipe out the world. Even if one plague is wiped out, by either cure or killing all of it's infected, the other can still win the game for both players as long as they finish the job.
Defeat
When both plagues are wiped out, the game will end in defeat.
Starting Location
Like in Vs. Different starting countries also gives different amount of starting DNA, unlike Vs. Mode, you can see what country your partner has started in and nothing will happen if you infect their country.
Differences from Vs. Mode
You can see what traits your partner has evolved, however, keep in mind that when you evolve one trait, it'll be drastically more expensive for your partner if they also wish to evolve it. Devolving your trait will remove this penalty for your partner.
There are two additional active abilities along with Unscheduled Flight: Infectivity Boost and Lethality Boost. Infectivity Boost like it's namesake, drastically boosts the infectivity in the country(s) you put it in while Lethality Boost will drastically increase the lethality in the country(s) you put it in.
Both players will get bonus DNA as long as their country still has infected people in them.
New to this game are Cure Labs, they are randomly set up in countries and specifically targets the disease that is the bigger threat before the lab is set.
To destroy the labs, you have to kill off the country the lab is located in.
These labs will skyrocket the cure and likely cause one of you to get cured very quickly.
Therefore, it is very important both players get discovered at the same time and spread out their threat level so the world don't just focus on cure one and then the other.
If one player is wiped out, they can still aid their partner by sending them to uninfected countries with Unscheduled Flights, quickly infect a country with the Infectivity Boost ability, kill off a country with the Lethality Boost ability or devolve their previous traits to make them cheaper for their partner. Additionally, the eradicated player will receive DNA regularly.
