Rust Gamemode - fortress assault

I'd like to make this game mode myself but I'm getting a little overwhelmed with the programming. I just wanted to throw this out there with some of the ideas and maybe one of you more experienced / productive guys might like to give it a bash! It's something that I'd like to play anyway!

Fortress Assault

A 32(?) player team based defend / assault mode with roles, on a set round timer. The attackers must attack the fortress and one of them must authorize on a cupboard inside to win. The defenders must defend the cupboard.

Some of the specifics I've laid out prior to looking at the code were:

When a player connects, they are assigned a team and teleported naked to an armoured room to select their kit. Hopefully get a GUI up in time so they can select the team and kit easier if the teams aren't already unbalanced.
When they select their kit, they will be teleported to their teams starting area and can spawn.
Rounds last for 8(?) minutes.
If it's the start of a new round, the game will not start until there are at least two players sleeping in the spawn area for each team.

Attackers:

Demolitionist x 2 Max. Only class with C4, pistols only(?)
Rocketeer(?) x 1 Max
Rifleman infinite
Assault infinite

Other players must protect the demo guys.
Respawn in armoured room to re-select kit(?). Needs looking at.
Have large medkits and armour as balance to defenders superior position.
One of the attackers must authorize on the cupboard inside the fortress for the attackers to win.
Attackers initially spawn further away than the defenders, to give the defenders time to get into position.
One attacker needs to authorize on a cupboard on the route up to the fortress to move the attackers spawn point closer.


Defenders:

Rifleman infinite
Assault infinite

Must defend the fortress and stop the attackers authorizing on the cupboard to win.
Spawn doesn't change and is closer than the attackers.
Has less armour than attackers and only bandages for first aid.

Just a few of the things I was thinking anyway but yeah.. any thoughts?
