Mirelurk bait grenade is a thrown weapon that was cut from Fallout 3.
Characteristics[]
The mirelurk bait grenade is a special frag grenade, which based on the name, could act as bait to attract or lure away mirelurks. It is unimplemented: it is impossible to obtain without using the console, and it does not work as mirelurks simply ignore them. It uses the frag grenade's explosion effect and does zero damage though it still causes the concussive effects if the player stands too close to the explosion.
This weapon can not be found anywhere in the game. It is obtainable only via console command on PC. To get mirelurk bait grenade, use the console command: player.additem 30664 1
