Agar.io type game Custom Gamemode needing made Serverside NodeJS

General information for the business: Online MMO
Kind of development: Customization of existing program
Description of requirements/functionality: Hi

So basically I run my own Agar.io type game

https://goo.gl/g1YTwk

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 https://github.com/Barbosik/MultiOgar for my serverside
Specific technologies required: node.js, html5, css, javascript
