Concept:
A long time ago someone in a playtest came up with the idea of a handheld flamethrower in the form of an aerosol can, and it was so unstable that it should blow up the player when overused and we loved it too much to let go.
Why we made it:
After the Dog was announced for the Police, everyone asked "what's the protester equivalent"? A Pitbull seemed far too controversial and a Jack Russell seemed too rediculous even for the meme team, instead we looked the opposite way and decided to group all our most crazy weapon ideas into one class, the Improviser.
Their in-game role:
The ultimate crowd controller, whether he's hosing down officers with streams of fire, smacking people over the heads with a cactus or throwing Molotovs to cut off reinforcements. The Improviser is a force of pure chaos, just be sure to avoid 1v1s against the heavier, more competent fighters.
