We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.

The frag grenade is an explosive weapon in Fallout: New Vegas.
The standard thrown explosive device used by militaries worldwide before the Great War, the frag grenade causes a lethal blast sending metal shrapnel flying in all directions up to 14 yards. It's useful against groups of unarmored enemies, or for hitting enemies around corners by banking grenades off walls. To throw the frag grenade, simply press the fire button; the longer it is held, the farther the grenade will go. The arc and trajectory at which the player is throwing it is also a major factor for determining the distance it will travel and land.
