You need to explain a lot more as to why you think it should be added. Please go into detail about how it would work, and how we can differentiate the gametype so it's completely original for our network. Will there be any kits for the game? How big will the maps be? How many layers will there be? Can players respawn? How many players per game? How long will the game last for? Since players tend to stay in one area sometimes, will there be a countdown to when the floor will disappear so players are forced to move down a layer?
We need to know this sort of stuff, please go into detail/describe why you personally think it'd make a good addition to the Network, and what you think should be added to the gametype to make it original and competitive.
