The Madhous! is obtained randomly from any suitable loot source but has an increased chance to drop from Mad Dog located in Lynchwood.
Special Weapon Effects
It's a Madhouse! A MADHOUSE!!! – Increased damage, accuracy and magazine size. Bullets fired will follow a slightly swerving path that swerves back and forth left-right or up-down (orientation is random), then will split into two upon impact and bounce; bullets become faster after every bounce.
Usage & Description
While the Madhous!'s split projectile effect would seem to be immensely useful for combat in enemy-rich environments, the swerving, slow behavior of the initial projectile almost completely nullifies the benefits of the split projectile effect and the damage and magazine size boosts. The projectile path is so random that shots fired at a distance of one to two body lengths not only have a chance of missing the targeted body part, but are also likely to miss the target entirely.
Despite these issues, the Madhous! has some beneficial use against large mobs of enemies, particularly when aimed at the ground near the center of the group of enemies. The random trajectory of both the initial projectile and the split projectiles will provide ample coverage over a somewhat large area, though the likelihood of critical hits is nearly zero when using the weapon in this manner. Outside of this, Madhous! is a 100% niche and is easily outclassed by all other Bandit Legendaries.
On Day 19 of the Borderlands 2 Loot Hunt, the Madhous! and all other Bandit assault rifles had an increase in magazine size from a hotfix.
Even with Gaige's Close Enough, the Madhous! is impractical because when the projectiles split and ricochet, it does so at a fixed angle. Thus, even when Close Enough activates, the split projectiles don't fire directly at the enemy, but rather to the left and right, making missed shots a common occurrence.
The Madhous! was originally intended to be a part of Mad Dog's loot pool. However, he was mistakenly given a loot pool identical to Madame Von Bartlesby and as such, he dropped the Baby Maker instead. This was patched in Early August 2013, and Mad Dog now has an increased chance to drop the Madhous!
The Madhous!'s weaving bullet paths are very similar to those of the Madjack revolver in Borderlands.
The Madhous! has the same material as the Badaboom.
