It looks like Zane has finished his Portal-inspired sentry gun and left it at the lab overnight, allowing it to evolve consciousness and determine, however correct or incorrect, that humans are the biggest threat to their own survival.
I would suggest against going to the lab any time this weekend until we can get a cleaning crew out there. But if you happen to have a portal or gravity gun, you know, feel free to take care of it yourself.
I was zapped yesterday. It etched “Balls” onto my forehead and laughed. :-( At least it didn’t launch any nukes yet.
