time bomb schematic!

where is it? i can't find it!

 

Randomly in tech shops I'd imagine.

 

It has a 3% chance to appear in a gun smith's stock each day. So be patient and check your local gun smith on a regular basis.

 

thanks everyone.

i'm also looking for the schematics for:
-electrocution grenade
-concussion grenade
-paralysis grenade

(my throwing-master tech-dwarf is awesome!)

 

Same store, same 3% chance of appearance for each of those babies, gun smith is your answer.
