In other words, the singularity is way too easy to sabotage. I swear, every other round someone lets that thing out...
I don't even know HOW to sabotage it without a bomb...
or you could pull a feep and make an impenetrable fortress inside it.
make glass walls so anyone trying to break into the area will get zapped by the singularity field, tile the grounds and lattice them, take out the singularity generator, fill the room with air, make a nice little room you can walk around in and make it so you cant go near the lazer so you dont get shocked, then chill there for the entire round.
you wont get killed if you make proper walls since they need to get close to it to get rid of the walls and the laser will shock them.
