The description:

When the battle starts you have to get a rocket pack from the goblin on your ship. You have to use the rocket pack to get to the other ship. On that ship is a flag of your enemy, you have to take that flag to your commander. Once there you can choose to enable your guns, or disable the enemy guns. The goal of the battle
is to destroy the enemy ship. Guns are activated only for a limited
time and when disabled also for a limited time. So choose wisely.

So what does this battle have:

• Worldstates
  
• Vehicles
  
• Queue system
  
• PvP messages
  
• Rocket pack
  
• Flag system
  
• Phased
  
• And some other not important things.
  

I also made a youtube video of me
playing around, showing a bit what it looks like. Though it didn’t
really come out good. Its a bit lagging and the quality isn’t perfect
either but you should be able to see what it looks like =P

The script: [Only admins are allowed to see this link]

Spawn npc 4251 and you can queue in. His flags are probably not set
to gossip, to do this just use the command “.npc flags 1″. I changed the script by adding the line of that npc at the top. You can easily change the npc id there if you wish to.
