The breach alarms echoed around the site, reaching every corner of the building as it the warning lights flashed so everybody knew to either respond and contain or run for the breach shelter and evacuate according to their position as staff.
You were an SCP, though. You had a cell you had no choice but to live in, you couldn't go anywhere while you had to listen to the distant gunfire, alarms outside, screams, and roars of the many escaped monsters from this site.
Without warning, with a loud crash and debris flying everywhere, SCP-682 slams into your cell wall, breaking the entire thing down before scrambling back out and rushing down a corridor, several guards more focused on chasing it down than doing anything about you, and now you're also free.
The guards report your cell's destruction into their comms, but don't dare to look back; there wasn't enough staff to handle every single SCP all at once. They were still awaiting the backup being deployed here from other sites to help.
