Heatwaves, lightning storms and rats
The latest DLC forPrison Architectwas both announced and released yesterday.
That includes weather such as lightning storms, heatwaves and snow storms, but also rat infestations.
Lightning can strike guards and inmates, knocking them unconscious, or cause structural damage that leads to flooding.

It’s better if you plan for these potential disasters in advance, however.
There are disaster relief grants, too.
As DLC for Prison Architect goes, I like the sound of this more than most.
