Incinerator

The Incinerator is a Flamethrower in Fuse.

Incinerators deal damage in a moderate arc, though the fire doesn't travel too far away from your character. Incinerators melt enemy Soldiers and Seekers, but it's tough to use them against other Leadfoots  and Enforcers. Naya is the best person to weild Incinerators, because she can cloak and sneak up on her victims. That mitigates the range limitation on Incinerators.

Another trick is to use Incinerators in tight corridors or near doorways. That way, enemies at long range can be avoided.
