Internal namesCodenames used for this hero in the game files:
Viper
Vyper is an impulsive outlaw that gets thrown in jail as many times as she escapes it, building a reputation among a number of criminal allies and enemies across the New Jersey Tri-State Area.
When it comes to breaking the law, not getting caught is a pretty important part of the job. Vyper never got that memo. Luckily for her, if there’s one thing she’s better at than being arrested, it’s escaping out of jail.
Having done time in every major prison in the tri-state area, Vyper has built an impressive network of street level lowlifes that owe her one. She’s also built an impressive network of street level lowlifes that want her dead, but she tries to focus on the positive.
