I think a map based around a multiple story building would be interesting.
It could begin by attackers attempting breaching the door with C4.
Entering the building puts attackers spawn at ground level, and defenders on the third floor. The second floor contains a vault that must be breached.
The routes to the second floor consist of stairwells and an elevator - the elevator can be operated \ deactivated by a generator.
Breaching the vault moves the defenders to the roof, where there is a getaway helecopter waiting to have the credit container delivered to win.
Attackers spawn in on the vault floor and must make their way to the top and deliver the container.
I think it could be very fun gameplay and scenery, and of course adjusted to fit gameplay.
It could be a bank building or a laboratory- the drugs being stolen in Bridge have to be manufactured somewhere!
