Before The Flood map

Before the Flood is a parkour speedrun map where you must reach the top before time runs out. The map features a set of ten courses with identical rules and goals, but each has a unique design. 

Every run begins after a 30-second countdown. Once the race starts, you need to climb quickly because the liquid level in the room will rise roughly every five seconds. If you fall into the liquid, you must start the run over from the beginning. The key to success is memorizing the courses through repeated attempts. You can also adjust the difficulty in the lobby by changing the flood parameters. Additionally, the map features a high-score system that rewards you for successful runs.
