Mister Gutsies use pre-War era plasma projectors for long-range combat and flame throwers for close-range fighting. Furthermore, what appears to be hardened steel plates used in their construction make Mister Gutsy models tough to beat.
The hardened Mister Gutsy has significantly higher damage resistance than the regular Mister Gutsy (on par with the average sentry bot). The Mister Gutsy prototype is a series of robots that preceded the Mister Gutsy line, featuring the same weapons and AI but having weaker armor than their production model cousins.
Mister Gutsy units have two weaknesses: they can't use both weapons simultaneously, and will always switch to their flamer when their target is in range. Nearby explosions or crippling its thruster can temporarily knock it out of the air. Mister Gutsies are more resistant to bullets than other robots, and armor-piercing rounds seem to have little effect on them. Their voice is also different from the East Coast variants, being quieter and higher pitched.
Mister Gutsy, unlike the Mister Handy, is a dedicated combat robot and is easily distinguished from the Handy by its olive drab paint job, US Army insignia, and the replacement of its British butler voice with that of an American drill sergeant. It was commissioned by the United States Army just before the Great War in 2077. They have distinctive "military" personalities, and an advanced AI similar to that of the civilian variant.
These upgraded Mister Gutsies can be found guarding the crashed Vertibird in the southern Mojave, along with hardened sentry bots. Their HP exceeds a regular Mister Gutsy's by fifty points, and their general toughness is on par with the average sentry bot. This is a result of their 10 Strength attribute, double that of their normal variants.
The Mister Gutsy prototype is a weaker variant of the regular Mister Gutsy. It uses the same AI and is equipped with the same weaponry as the regular series, but its armor is significantly weaker and it can be disabled easily. One example of the prototype can be encountered when exploring one of the empty houses in Nipton after the Legion's raid. This Mister Gutsy has already claimed the life of an unwary legionary, and is immediately hostile when entering the house. According to notes on a terminal in the same house, the resident at that time had repaired the robot in order to impress any potential new women in town. Another prototype may be found inside the solar collection tower at HELIOS One at lower levels.
Mr Steels are Mister Gutsy robot derivatives found in New Vegas Steel. Essentially re-painted as Mister Handy robots, they still come complete with plasma projectors and have 100 HP and 25 Damage Threshold, making them very durable opponents. They use the same skin as a standard Mister Handy.
The Mister Gutsy Mark series only appear in the add-onOld World Blues. The series runs from Mark 1 to Mark 6 (with the exception of Mark 2, which cannot be found).
Compared to the other Mister Gutsies found in Mojave, the Mark series in Big MT are harder to defeat, with their speed and durability being enhanced. They also work with other robotic/human enemies or appear in numbers. Two or three types may appear at once, though this is a rare occurrence.
His quote "There's nothing I like better than the smell of plasma in the morning!" is a reference to Robert Duvall as Colonel Kilgore's line "I love the smell of napalm in the morning" from the movie Apocalypse Now.
