Perhaps they were right, for I have created this monstrosity, which combines breakfloor, melee_checkers, and Arena_grid_walls into a single map!
you spawn on top of a nighttime melee_checkers, with a new addition: There are now four layers of breakable checkerfloor! I have also replaced the 2D skybox with Arena_grid_walls, and instead of being killed after falling into the floor, you are teleported to a corner of grid walls depending on where you were on the checkers arena, where many people will lose their lives amongst each other in this new arena, with nowhere to hide! after five minutes of the round starting, the control point in the center of Grid_walls is unlocked.

Testing in singleplayer:
You may need a bot in order to actually spawn if you wish to test out the map alone.
Type: "sv_cheats 1" then "tf_bot_add" in console to spawn a bot to test the map out.






EDIT: I forgot to mention, I made sure that the newest weapons are also prevented from being used. (No laser soldier rape!)
