Heavy Incinerator (Broken Steel)

The  is a weapon which will be added to Fallout 3 with the release of the Broken Steel downloadable content pack in May 2009.

Characteristics
Apparently the Incinerator works like a kind of mortar, lobbing fire over its target in lazy arcs, and it was also mentioned as a projectile flame thrower in various previews. It has what appears to be tanks of flamer fuel on the side.
