Something was wrong. The Administrative Department issued a Code Purple, eliciting personnel across Site-19 to keep an eye out for a possible hostile sabotage. From that point... things only got worse.

A strange green mist enveloped the site and an unusual minty smell invaded your nostrils. You knew what was about to happen, and you dreaded it.

Soon, alarms began blaring and the P.A. system came online, with a male voice coming through.

"An SCP-610 outbreak has taken over the Heavy Containment Zone, nearby personnel evacuate IMMEDIATELY. Response forces are to incinerate all biological material for recontainment."
