Two Rippers instantly jump into the vents. The single remaining Ripper calmly walks up to the window. It extends its blades, and jumps towards the window, with the intent of leaving a scratch. [1d10 -> 4 -> Glancing Hit] A loud noise follows, and a large scratch is left on the windows surface [1 damage].
The observer does not consider a leap at the window to be a communication attempt. He realizes that he really, really should sounds an alarm at this point and pushes a couple of buttons on the wall of his room. Suddenly loud sirens blare everywhere. The two vent Rippers get a full blast of the sirens noise as it's carried along the tiny space. Luckily they do not have eardrums that could be shattered. Along with the alarms, several gates within the ventilation system open, dispersing the environment specifically created to contain the nanobots. As the oxygen hits their surface, the Rippers momentarily appear to burst into flames, as the nanobots left on their surface burn off.
The lone Ripper follows its two brethren, who by this point have cut through a grate, and emerged out of the ventilation system and out into a random corridor. Unluckily a soldier stumbles upon them and pulls out his handgun.
Two Rippers present. Third will arrive in a turn.
