Take over Base (or a other name, don't know a name for it)
There are 2 teams, 1 attackers, 1 defenders.
The Attackers need to take over a castle like thing. This will be in a mountain area.
The Defenders need to defend it until the round is over, or when all attackers are killed. The Defenders will stand on the wall, and they can go under ground to get before the castle.
The Attackers need to kill all Defenders, or take over de base.
How to take over the base?
They can enter the castle, and then they need to go all way up to the castle, and hack the computer/steal the key (depends on what for castle). That will be similar to defusing the bomb in destruction.
