Handheld energy weapons

[rom65536]

Most of these weapons were (and still are) extensively used in the Judge Dredd strip. Riot Foam is basically specialised utility fog that allows the target to breathe, but stops them from doing almost anything else.

In OA we have mobility denial ribbon, which does something similar if used correctly.

I prefer the "mobility denial system" that's basically a very slippery goo you spray on a crowd. It turns a riot into an episode of Benny Hill (just add Yakety Sax and women in their undies).
