Live, You Idiot

Before the enemies arrived, I had already planted a failsafe. A last-ditch defense in case we were ever forced into a corner.

Right at the center of the junction, I set up two antimatter grenades and hooked them into a mechanism that would release their safeties with the press of a button. It wasn't anything too sophisticated—just a setup using electromagnetism, a folding knife, and a length of string.

Huh? You're wondering how I managed to plant it with enemies crawling all over the pathway?

Simple. People generally only look within or below their line of sight. They don't tend to look up unless prompted—or unless they're searching for something that's supposed to be high, like stars... or airplanes.

And you guessed it. I set the grenades above the corridor light fixture right at the intersection, rigging them with the fixture's existing electricity for this little trap.
