Yup, that pretty well sums it up...
Awesome... My friends and I have kicked around the idea of that scenario for years. Good job! Too bad we don't have anything like that around here either... Had a HACA/ARMA group for a while, but it died out. Now I just have to stick to the LARP thing.
The only flaw though... What if they're Romero zombies? (0.0)
Or that nasty business with the blood from 28 Days Later?
In some instances, a gun would be far better... But just as swords dull and need maintenance, guns need regular cleaning... And a whole warehouse of bullets does you no good whatsoever if you have no clips left on your belt.
I'd still take a good katana any day, and trust my swordsmanship over my marksmanship. I guarantee, it only takes one swing.
