Precise time: 54:59.800

October 8th, 2023 mod note/update: Due to previous miscommunication of rules around usage of developer console to manipulate the game, a penalty of 2.067 seconds (62 ticks) has been added to this time to ensure no unfair disadvantage to future runners. For any questions, please ask in the L4D speedrunning discord. (Old time was 54:56.750 (video) - run was retimed with demos, which is 54:57.733 + the 2.067 penalty)
