Arsonist

"This soldier LOVES to play with fire! He’s whipped together some Molotov Cocktails to turn the heat up on the enemy, and keep the heat coming as part of their DoT attacks."

- IKKI describing the Arsonist on the 1.5 Patch page.

The Arsonist is a unit released in update 1.5 and is able to cause burn every time it uses its Molotov Cocktail. It also has a secondary weapon (SMG) available at rank one, with a range of 1.

Trivia
The Molotov Cocktail had its origins in World War Two, during the Winter War between Finland and the Soviet Union. The Finns blamed Soviet foreign minister Molotov for the war, so they named their 'cocktails' after him.

The Arsonist is the only unit that doesn't cost nanopods to start with two different attacks unlocked at level 1. Of all the attacks that can inflict extra 10 damag by the burning, the Molotov Cocktail is the only one with a 100% chance on hit (the attack can still miss).

The Arsonist is currently the only trooper with a red helm.
