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 projectile flame thrower in various previews. It has what appears to be tanks of flamer fuel on the side.
