Mirelurk Bait Grenade

The Mirelurk Bait Grenade is a special frag grenade, which based on the name could act as bait to attract or lure away Mirelurks, similar to the Bug Bait found in Half-Life 2 that attracts Antlions. It is unimplemented: it is impossible to obtain without using the console, and it does not work as Mirelurks simply ignore them. It uses frag grenade graphics and does zero damage though it still causes the concussive effects if the player stands too close to the explosion.

They were intended for The Wasteland Survival Guide, when Moira Brown sends the player into the Anchorage Memorial, and are mentioned in the script for the quest.
