It was! It was a werewolf! No wait!
MORE.
There was a whole pack of werewolves rushing through the airport.
Lead by a massive white wolf who seemed to be targeting the Purge leader.
Martin peered at the dark and grainy screens, he could barely make out what was going on.

[i]None of this shit had been in the briefing.[/i]

With rushed pace Martin studied the controls before him, most were used to manage flights, turn the runways on or off, contact radio's...
Found it! Intercom!

Through the darkness a crackling voice boomed trough the airport.
[b]"Void! You're outnumbered and outmaneuvered. Make your way to the airplane you came in and surrender yourself there!"[/b]
Martin turned on the runway lights and moved some sliders around, the massive bright focused on Void from behind the few Purge troups standing ground, blinding him and making it impossible to discern anything but their silhouettes.
Void had two ways he could go, back to the plane, or back inside through gate 8.
Martin knew Void wasn't going to comply, thus the true death was the only solution. From what he could tell he chose Kami for this purpose.

Now his voice boomed through the terminal.
[b]"Purge leader! North!"[/b]
A few meters to Kami's north was the entry to gate 8, its reinforced doors slowly closing, he could make it through!

[b]"Fuck that!"[/b] Hale shouted as he jumped down from the pillar as it came crashing down on the entrance and a bunch of humans entering the building from the south.
[b]"Cut him off!"[/b] He bellowed as he started to circle around, hoping to block Kami's path.
Several werewolves stuck to hounding their prey, others followed Hale's example and moved to block his path.

Martin placed the microphone next to the speakers inside the control tower, and flicked them on.
The feedback loop, played over every speaker in the airport, caused a ear piercing high pitched tone that resonated through the terminal.
Loud and sharp enough to cause serious pain to humans, Martin put on his headphones as protection.

Hale, even though he had neglected to train his senses stopped dead in his tracks, clasping his hands on his ears.

[i]The only thing louder than the screaming of the speakers was the howling of the wolves in pain.[/i]
