Warmonger

 is a perk added to Fallout 3 with the Broken Steel add-on.

With this perk, all custom weapon types become available to you without the schematics. Taking this perk immediately gives you the level 3 schematics for all weapon types you did not already have.

 * This perk works perfectly for the Nuka Grenade and Bottlecap Mine. However, for all other schematics, you must have at least one schematic for the weapon before taking this perk or it will not work correctly and will produce the weapon as if you had only the level one schematic. For example, if you had a Railway Rifle schematic prior to taking this perk, but you did not have any Shishkebab schematics, then taking this perk will cause you to make Railway Rifles as if you had the level 3 schematic, but Shishkebabs as if you only had the level 1 schematic. It is thus advisable to still acquire at least one schematic for all weapons other than the Nuka Grenade and Bottlecap Mine prior to taking this perk. (Unconfirmed) In the Xbox 360 version, it functions as intended. Also note, that if you aquire a schematic after taking this perk, it will not raise it to v2, meaning you are locked at v1 of the weapons.
