One of our most popular "handle with care" items. Will explode on activation, covering a large area in roaring fire. Would almost be cozy if the flames did not burn hot enough to melt steel.
— Item Description
The Incendiary Grenade is an unlockable Throwable for the Gunner. It is a firebomb grenade which appears similar in shape to the real-life German stielhandgranate (stick hand grenade) used in the World Wars. The handle is larger than the payload container, the latter being colored a bright orange.
Instead of producing an explosion, the Incendiary Grenade will carpet any area where it lands in a roaring hot fire, roughly arranged in a circle shape. The fire effect behaves similarly to the Sticky Flames attribute used by the CRSPR Flamethrower, lingering on the ground and damaging anyone who walk through it (allies included, unlike the CRSPR's Sticky Flames). it will also raise their temperature, causing spontaneous combustion if an enemy lingers in the fire for too long. Enemies who are hit with the grenade's initial explosion will instantly catch fire.
The grenade will only explode when it touches a floor; it simply bounces off of surfaces and walls.
This grenade deals no direct damage whatsoever, even enemies who are directly hit with the grenade, while instantly combusting, will only take tick fire damage from the flames on the ground and while burning after leaving the fire circle.
Traces of a "Molotov" grenade were present in an early version of the game. It is likely these ideas blossomed into the Incendiary Grenade, which is more comparable to modern firebombs than the traditional molotov cocktail.
