New Biotech Killbox - The "Tox Box" | RimWorld (Biotech DLC)
This is the most brutal, effective killbox yet. Still a prototype, but wow is it strong.
Funny enough, it's the most humane killbox I've ever seen in RimWorld. It's got about a 60-70% survival rate, with downed pawns sustaining no injuries beyond the toxicity. With time, most all raiders will make a full recovery.
