Pandapool

It was a semi-quiet night in the city; everyone was busy with their own affairs, while the hero (that's me, obviously) was kicking the asses of mobsters in a building.

Come on, that's all you've got? I've fought less dangerous thieves and they last longer than all of you. Pssh, what a waste of time. Well, at least I'm free to go look for that biological weapon.

I walk among the corpses of mobsters humming a song as I reach the room where the weapon is.

Bingo bongo...mmm, it needs a password...umm

I pull out my gun and shoot the panel, causing the doors to open.

easy

I enter the room and start searching through the boxes until I find one made of metal with holes.

Could that be it?
Pandapool approached the box and examined it, noticing a note stuck on top that read "Danger: Living Weapon"
