This katana is a beta version of the samurai's sword in the Fallout 3 add-on Mothership Zeta.
It's a beta version of the samurai's sword. When it scores a critical hit, the target will fall to the ground just like the knockdown effect of the Victory rifle, the Gauss rifle and the Electro-Suppressor.
The katana can successfully strike about 333 times from full condition before breaking.
This weapon can not be found anywhere in the game. It is obtainable only via console commands on PC.
