File:Quake1.gif A Nail Trap is a hazard found in Quake which shoots nails (the same kind as the ones fired from the Nailgun) when the player approaches. Anything in its path will be hurt by these nails, including enemies. These traps can fire at varying rates, some shoot slowly while others fire in rapid succession. It is the Medieval equivalent of the Laser Trap. A Concealed Nail Trap is a Nail Trap that is hidden behind a portrait. Beyond the hidden nature of the Concealed Nail Trap, there is little else that makes it differ from the standard Nail Trap.
