Fat mine (Mad Bomber) (GRA)

The fat mine is an explosive weapon added with the Fallout: New Vegas add-on, Gun Runners' Arsenal.

Characteristics
After deploying it, the mine will detonate if a target enters a 1.4m (4.6 feet) detection radius. The detonation occurs after 3 seconds, dealing damage in a spectacular 20m (65 feet) radius and leaving behind a 7.3m (24 feet) radius irradiated zone (10 rads per second for 12 seconds). The detonation time is affected by the target's Explosive's skill.

The Fat mine qualifies as an improved holdout weapon, the most powerful of its kind.

Crafting

 * Note: Veronica and ED-E (with at least 1 rank of the Camarader-E perk) can also craft the weapon.

Locations
This weapon can be crafted by the player if they have taken the Mad Bomber perk. It cannot be found on enemies or in containers.
