The SMTX explodes into plasma instead of fire. I wanted some explosives that could melt METL, because THRM was the only one that could.

Whoops. Sorry about that.

DAVPPK: The link does work, I just clicked on it.
tman5000: It could be cyanide gas, but cyanide might make it in as another element in liquid and gas forms, as a poison

Thanks for that. Apparently the code for lava bomb didn't get copied when I merged my mod with the update.
