Agar.io type game Custom Gamemode needing made Server side NodeJS

Hi So basically I run my own [login to view URL] type game [login to view URL] I need a new gamemode system created which allows matches such as 2 vs 2 or 6 vs 6 (Team Scrimmage) It should work like Two teams of 6 players each battle it out in a preset map. This mode is designed for clan wars. Gameplay: Players start the game with additional mass. 8 bots roam the map to simulate real players. Each team spawns next to a mother cell, which will not respawn if eaten. There is a time limit 30 minutes. Viruses act like they do in FFA. Team Objective: Hold at least 90% of the total mass for 15 seconds. You need at least 2500 team mass to trigger this. Holding 100% of the total mass will result in an instant win. Hold the most mass when time runs out. There is a game which has this, so you can see an example of this. I currently use [login to view URL] for my serverside PLEASE DONT BOTHER APPLYING WITHOUT A BRIEF. YOU MUST READ THIS PROPOSAL!
