In appearance they look similar to a normal frag grenade, with the exception of a white cross painted on the side. When detonated, rather than a normal frag grenade explosion, Holy Frag Grenades explode in a manner similar to a mini nuke. There will also be radiation in the area it detonated.
Three Holy Frag Grenades are located in the basement of the church in the eastern part of Camp Searchlight, guarded by two golden geckos. It will only be available to players that have the Wild Wasteland trait. Players without the trait will find two mini nukes in the location instead.
If the player originally did not choose the Wild Wasteland trait, but switched to it using the Auto-Doc in Old World Blues before taking the mini nukes, then the Holy Frag Grenades can still be obtained.
The Holy Frag Grenade is a reference to the "Holy Hand Grenade of Antioch" which featured in cult comedy film Monty Python and the Holy Grail. The writing on the box next to the grenades is also a reference to a line in the film.

pcIn the first seconds after you load a game and you had the Holy Frag Grenade equiped, the blast of the Holy Frag Grenade may not do any damage to the courier, followers or NPCs, but there will be radiation on the place where the Holy Frag Grenade exploded. Damage from hitting the person will also be taken in account. [verified]
