The warning alarm was still active, it was quite disturbing for the two of them because all the zones were in a state of alert because of their arrival.
Ray and Parker headed back down the dead-end hallway, apparently none of the guards had noticed they were back yet. Arriving in the hallway Parker brought his radar closer to the hallway wall, he looked for the part of the wall that didn't merge with the ground.
Radar does not function optimally but can still detect people behind walls. It was quite helpful knowing how many people were there.
Parker had determined a suitable wall position, he pulled a small toolbox from his bag. Then stick it on the wall and activate it. The two of them kept their distance from the wall.
"Drrrrghhhhh"
A fairly large vibration but not a loud sound. Slowly the wall collapsed making a hole big enough for the two of them to enter.
