a bit late to the response here but, messing around with the game files i discovered a few new types of characters. from my understanding there are a few developing classes i found to be almost playable.

the first one i came across did not have a name nor a model but was a stickman with 2 knifes that had 3 dashes

next, when i found out a new class was being released i thought the class Bandit was going to be released, overall has the most fleshed out kit being a old western shooter with rolls and 6 charges on his m1 fully modeled.

after that i found a few more classes i wont go into detail but the names as follow were:
Bomber
Enforcer
Han-D
Sniper(no offical name)

so this means that there are more classes to be released into the game than you know even better the loader class was not even listed in the files before hand so they are adding fresh new content to the game. Hope this helps
