(A mobile transmitter would need to be slightly larger than a battlecruiser, devoted just to the transmitter and the engines. It would have to cease broadcasting whenever it moved)
Several of our agents stage a fistfight near one of the security checkpoints. The guards watch, but do not engage. We have one of the combatants blatantly fall to the ground, as if killed. The guards continue to watch, hands on their weapons but not moving. We decide to take the risk and have one of the agents throw a bottle at the checkpoint.
As if on command, the guards rush forward, shouting and firing their weapons into the air. One of them holds back, pressing a few buttons on a console. At this time, we activate the makeshift EMP, disabling all digital technology within forty feet.
The last guard pounds his fist against the console angrily, then shouts to the other two. They are, however, unable to respond, as several of our agents have sprouted probosces for infestation. The guns are not pointed at the sky anymore. Several of our agents take wounds, but the two guards are quickly subdued.
At the station, three attractive female agents have attempted to waylay the last guard, but he has opened fire on them, the crowd, and his former comrades. As we rush the checkpoint, a wraith pulls into visual range above.
We've got about a second to react. Do we keep rushing, or try to make this look different than it is?
