IG-88 Senses 4

The pathetic human security guards scrambled and screamed, lurching for their weapons. One managed to hurl a gas grenade, which did nothing but camouflage the movements of the five droids and made the security guards hack and cough themselves, blinded by their own tears. Shots rang out repeatedly.

The IG-88s used the circumstances to make sure all their weapons systems and targeting routines were properly calibrated. As the biological guards died one after another, the droids made necessary minor adjustments.
