Infected is a Modern Warfare 2 game mode where one player is randomly chosen to spawn as an Infected and aims to eliminate and infect Survivors.
The Infected player loses their gun in favor of a Combat and Throwing Knife. However, should they manage to take down another player, that Survivor will become Infected too.
The game lasts until either all Survivors have become Infected or time runs out and the Survivors are victorious.
Thanks to its fast-paced nature, Infected is potentially the best mode to finish your Integrity challenge and unlock the new Crossbow!
The Infected team has an unlimited number of respawns, allowing them to rush the opposing team with no consequences. However, Survivors have only one life each as dying has them immediately join the Infected.

As such, while the Infected is initially easy to handle, their numbers can become overwhelming, much like an actual zombie horde.
To deal with the incoming threat, Survivors spawn with one of a number of weapons, such as Shotguns, SMGs, Assault Rifles, and even Snipers. They also have equipment such as Claymores and Stun Grenades to help protect themselves from the Infected.
Fan-favorite Call of Duty mode Infected arrived in MW2 on February 15 with the launch of Season 2.

How to Win in Infected MW2 Game Mode
The Survivor team wins if there is at least one survivor when the timer expires. However, only the Survivors left alive will win in this scenario.
The Infected team wins if all players have become Infected. Bear in mind that the moment you turn into an Infected yourself, you then must eliminate all Survivors to win the game.

Infected was first introduced in MW3 and was more recently available in Modern Warfare 2019.
