Left 4 Dead Infected Bosses: Boomer

The Boomer

The Boomer is an obese methane-filled boss infected covered with boils whose main form of attack is projectile vomit, but also explodes when shot.

The Boomer's vomit is released in one large attack, and in the right circumstances can hit more than one target. The vomit obscures the vision of its victims, and also acts as a pheromone to both existing infected, and causes more to be spawned and attack the victims. This attack has a cooldown.

If the Boomer drops from a high enough height, it will "pop" and blood will spread to any Survivors in the immediate area, having the same effect as a vomit attack would.

When successfully shot at, the Boomer explodes which covers any nearby Survivors with puke.
