What about super trained humans or humans who had gained an upper hand due to accidents or other means?
To name a few ::
Batman <<~ Trained himself to reach beyond an average humans caliber plus invented gadgets to aid himself
Dare-Devil <<~ Due to an accident and extreme training he gained an upper hand
Captain America <<~ Government experiment changed an average soldier into a Super Soldier
Green Arrow\Hawk Eye\Robbin Hood <<~ All trained their eyes and skills with a single weapon of choice and now they are more resilient to defeat than your next door neighbor
Silver Samurai <<~ Trained his bones and muscles till he could become a master swordsman with skills far surpassing a normal swordsman with any kind of blunt or sharp sword styled weapon
Flash <<~ Gained super speed due to a chemical lab accident
IronMan <<~ Invented special weaponry to protect himself
IronFist <<~ A martial artist that solely focuses on his heightened monk type training
Catwoman <<~ A extremely trained individual who excelled herself in heightened agility based maneuverability
Task Master <<~~ A man with photogenic memory that can remember any kind of action that he witnesses and so can gain an upper hand while training to make himself physically stronger.
etc. etc. :genji:
I am just giving some suggestions here They do not need to be approved as I myself think that they would probably not be acceptable
If someone like that should enter then they should be turned into zombies and then we will have zombies in costumes running about :uh-oh:
But still what about Dead Rising type weaponry ? You know desperate times call for desperate innovations.
you know like taking an oar boat and attaching chainsaws on either end of them


I mean now that can really happen in real life... or wait maybe one would require mechanical and engineering degree ... or wait probablly not as I saw the items being used and created while playing the game.. they do look like they were made quite crudely :P
So anyone could make them in real life situations :)
but then again you already said that that weapon is not allowed but what about the other many combinations present in the game o.O
