Mako waited for another half an hour before Jacob voiced through the communication device that they were ready and that the guards were dealt with and the prisoners were ready in the basement.
"It's time," Mako said as he took out a small button from his pocket.
*PEEP!*
There were a couple of seconds of silence until...
*BOOM!* *BOOM!*
Explosions resounded at both gates of the warehouse. The guards near them were instantly knocked out while the ones that were outside were confused about the sudden sound and the ground shaking. They instantly realized this to be some sort of attack and that the guards inside may need backup to control the prisoners and stop them from escaping.
The guards inside were trying to collect themselves after being severely discombobulated from being very near to the blast. The guards in the lounge and those in an elevated position or the basement were the least affected and the quickest to react.
