The flashlight is a common object found in the Dead Space 2 video game. At the onset of the game, before Issac Clarke gets his first Plasma Cutter in the first chapter, he finds the flashlight in a compartment, alongside a Small Med Pack (items that restore health). The flashlight helps him to have visibility in dark places and allows him to defend himself against enemies by obstructing their vision.http://deadspace.wikia.com/wiki/Flashlight 

The flashlight has a similar appearance, handling and lighting as the Plasma Cutter, and is a harmful weapon against the enemy.The flashlight is light in design, however, it can break the limbs of a Necromorph and can make visible damage in conjunction with the melee (hand to hand combat: Punch and Stomp).http://deadspace.wikia.com/wiki/Flashlight 

In Dead Space 2, the flashlight is a portable battery device made by one or several dry cell batteries, inside the handle of the device, where the battery compartment is placed. A switch mechanism can be found between the batteries and the lamp. This switch controls the flow of electricity that circulates from the batteries to the bulb.http://deadspace.wikia.com/wiki/Flashlight 

Edgar Foster, a doctor on board the Sprawl who is encountered in the beginning of Dead Space 2, assists Isaac by giving him the flashlight to use around the dark areas of the Sprawl hospital (Titan Station).http://manofthehouse.com/gadgets/computers/dead-space-2-review-xbox 

At the end of the first chapter Isaac attaches a medical tissue cutter to the flashlight in order to improvise his Plasma Cutter.http://manofthehouse.com/gadgets/computers/dead-space-2-review-xbox
