So i have been playing RP for years and here are some i came across:
Superhero- Batman skin and fists did more damage, had a arrest baton, and stun stick, also could maybe have 25 or 50 more health than anyone else and of course this should be restricted to one person at a time and probably be a donator class.
Supervillian- Joker skin, had a lockpick, m4, deagle, keypad cracker, knife, so he would also be restricted to one person, and should also be donator class.
Food vendor- It's what it sounds like gets shipments of food and water and sells them to people.
Dog- So this one was weird, it was like a pikachu skin and i was thinking cause its a dog you can pay them a certain amount to follow you around and like a dog protect you, so its like a more fun security guard.
Mayor guards- Was the white combine restricted to two at a time, had a stun stick, m4, deagle, and a arrest baton, but couldn't do police stuff cause of course there main job is to be with the mayor at all times.
Black market dealer- This guy would sell grenades, c4, keypad crackers and lockpicks and knifes.
Journalist- the journalist had like a printer where they typed a article and printed the papers and put them around town, it was very cool, but again i don't remember how the printing the newspaper worked.
Dispatcher- This one is complicated, all characters would have to have a cell phone and when in trouble would call 911 and the dispatcher would pick up and talk you like a real life dispatcher and tell the police where you were and what you needed help with.
So these i have seen throughout the years and felt like they were very cool and should be added, some might be dumb like the dog but i hope you guys like my ideas. If interested i can link skins to all these special jobs.
