Infection

Infection is a part of No More Room in Hell's gameplay. The disease that makes the survivors rise from the dead is a mutation of Encephalitis Lethargica, named 732-ZH.

The survivor can get infected if a zombie grabs the player and bites him/her. If that happens, three things might occur, apart from losing health:

a) Nothing (No infection or bleeding)

b) You get infected

c) You bleed

Options B and C might happen at the same time, meaning that you can get infected AND bleed.

The infection
While infected, what appears to be veins start to form at the corners of the screen and a grey tint is applied to the screen. As the infection progresses, the screen starts getting darker and the background music intensifies, to the point where the survivors succumbs to the infection and dies.

In the infection state, the player can still do everything a non-infected person would do, but even with friendly fire turned off, the infected survivor can be shot and killed, awarding the Kevorkian achievement to the killer. The infected survivor can also shoot him/herself if the player has a gun with ammunition, awarding the Social Responsibility achievement to the player. To do this simply equip the gun, press K and shoot.

Infected survivors always respawn as uncontrollable runners.

Another way to become a Runner it to be directly killed by zombies. One way to notice if the transformation will occur is the body. If it falls without ragdoll, it will raise as a Runner. If not, it will stay dead.

Ways to control the infection
There are 4 ways to get rid or stop the infection, two of them involves the death of the infected.

The first one is taking Phalanx pills (this give 3 more minutes to the player's life per use). The second one is using Gene Therapy (this completely stops the infection and makes you immune).

The third way is getting someone to kill you (see above), and the fourth and final way is killing yourself (see above).
