This flamer comes equipped with a backpack to store the flamer fuel. Unlike other flamethrowers that have an ever burning pilot light, this flamer has a white-hot wire protrusion that ignites expelled gas.
The rapid-torch flamer's stats are almost 100% identical to the regular flamer, except its attack animation. This difference does actually have an in-game impact, although minor – see below. The rapid-torch flamer is very sensitive and can expend a full tank of fuel in only a few seconds.
Compared to the regular flamer there is a slight delay before fire gets out, so in order to just expend one point of ammunition the fire button needs to get hold only for a little bit – holding it longer will expend two points of ammunition. So with this variant one can conserve ammunition a bit better than with a regular flamer.
This also works for the more "spray-n-pray" type player, as the rapid-torch flamer basically acts like a semi-automatic flamethrower. Rapidly tapping the fire button will let flames shoot out as fast or as slow as wanted.
