This is the hero rescue mode from Heat Street: Survival (specifically the outdated version 0B334). Heat Street is amazing but I really liked the hero rescue portion of it only and didnt want anything too different so I disabled the cash shop. Cash should instead give you a damage bonus. I am not a coder so to make this work I just looked through the workshop editor and disabled stuff that seemed like it wasnt for hero rescue. I probably didnt disable everything correctly but it plays like how i expect it to. Adjust the difficulty by changing team 1 general settings and/or the last line in the workshop editor. If you like the mode check out the full version with 0B334. It is outdated but is the latest version I could find that still has hero rescue. Check out code CR67F for the non outdated version of the mode this game is based off of.
*ONCE YOU SPAWN YOUR CHARACTER, PRESS 'INTERACT' TO START THE GAME. THE MESSAGE THAT TELLS YOU TO PRESS THE BUTTON TO START THE GAME IS DISABLED BECAUSE IT ALSO MENTIONED THE SHOP MENU :D
Ive only tested kings row but I think it might work on these maps as well:
