Prosk and Sentium are no strangers when it comes to corporate espionage. Thanks to the political atmosphere of Illal, black market deals are far too commonplace. Trade smuggers never actually touch down on Illal. The reason being not the Gigastructure, but because of all the fighting.
How it works: this game mode would have no time limit. A 'box' is dropped on the map in a random location. Both teams must find, and retrieve the shipment.
Upping the ante: Illal has very strict laws about smuggling. Any persons caught with illegal paraphernalia will be sumarily dealt with. (What this means): bots are placed on the map. They do not shoot unless provoked, OR you are spotted holding the 'box'.
An alternative: instead of bots spawning at the start of the match, they instead spawn when the player holding the 'box' is spotted. Note, the bots only spawn when the player holding the box is sighted. They will roam the map until the 'smuggler' is found.
Before I forget: bots wont deal damage, instead they just slow you down. Makes it easier for (whatever passes for law enforcement) police to catch you.
