The dead ringer swep is made by Necrossin.

What is the Dead Ringer?

The Dead Ringer is a unlockable in the game Team Fortress 2 by Valve.
With the Dead Ringer enabled, as soon as you take damage you cloak, and leave a fake body behind, letting your enemies think that you died.
Necrossin coded the Dead Ringer into a swep so you can use it in Garry’s Mod.
