This will change your katana in to a super power which practicly kills every body around you (and sometimes cars) WARNING! THIS MOD MIGHT MAKE YOUR KATANA INVISIBLE so please back up your weapon.dat file.
So Funny! I'm new here to the Garage and just uploaded my first mod yesterday very similar to this one. I would have removed mine since this one is already up, but i just tested your katana data mod and it is FULL OF BUGS THAT CRASH THE GAME AND SOMETIMES WONT LET YOU USE ANY OTHER WEAPON! you tried to make it way too powerful is the problem! and in your mod the katana is invisible because you added (EXPANDS) to the "SPREAD" in the data! GOOD TRY THOUGH!
This mod will definitely come in handy! This kills everybody within range with ONE swipe of your sword, even if they are behind you. Gives "crowd control" a whole new meaning. The ideal mod for those gamers who value their personal space.
