So I had an idea for a map. Frustratingly, I cannot build maps for the life of me nor have the time to practice. This map will need a lot of balance tweaking, but this is just the concept and is certainly not set in stone. Feel free to build this map for yourself! I don't care whether credit is given to me or not, but if it is it'll be greatly appreaciated!

Map backstory/theme:

The map is themed around a giant dam which Blu is trying to fully open to flood and destroy Red's water filtration plant. It has lots of rocks and crags similar to PL_Badwater Basin.

My thoughts for the map's name were CP_Mann damm, CP_Flashflood and CP_Drowning, but feel free to make your own name for it if you don't like mine.

Map layout:

Anyway, The map starts with Blu's spawn along the bank of a river which leads into a water filtration plant owned by Red outside the map boundaries. There is a small shack with a control point in it further up the riverbank. Moving on there is a small slope that moves through a choke and a tunnel leading off to the right, both leading to a security building containing a control point. The map then makes a U-turn and goes on top of the dam, with the final control point being in the centre. Red's spawn in at the far side of the dam with various cover objects in front of it.

Mechanic ideas:

Frontline! asset mechanics (duh)

Body of water on upper side of dam contains hole in the dam which, when swum into, launches the player through the dam into the river below near the first point

Upon Blu capturing the final point the dam would fully open and a large killbox of water would flood the lower area of the map (first point and blu spawn), and continue into outside the boundaries until it hits and destroys the filtration plant

Just go ham with it!
Thanks for taking the time to read this concept. :3
