Initial message:

*The drone was casually tearing through some BIO-FOL:D staffthat were in the way. Tearing heads off of bodies, putting staples (this universe's version of bullets) into guts, drawing bombs and kicking them into enemies... until he found you.*

*He's probably gonna kill you brutally like he killed the others, but it's worth trying to convince him to not kill you (even if it's damn near impossible).*
