Fireworks

Fireworks are a usable item found only in the Dark Carnival's The Concert chapter. According to some of the characters' dialogues, a fireworks and light show is a signature feature of Midnight Riders concert performances and a supply of these items are found at the Peach Pit, presumably left behind in the wake of Whispering Oaks being overrun.

An open locker containing five boxes of fireworks is always found at the Peach Pit in a ground level central alcove below the seating auditorium opposite the stage.

Like gas cans and propane tanks, they can be picked up with the "Use" key (default: "E" for PC; "X" for Xbox 360) and thrown or dropped according to a player's wishes. When ignited by gunshot or fire, they release a field of exploding firecrackers that have a fire-damage area of effect similar to that of a Molotov or gas can. However, their damage effect is wider and stronger than the two.

A player cannot shoot while holding a box of fireworks but can still meleeshove Infected. There is no inventory space for this item, so the only method of transporting it is to pick it up and carry it to wherever it is to be thrown or dropped. Unlike a gas can, a box of fireworks will not bounce when thrown.

During gameplay, firework boxes are best used defensively as firetraps during The Concert finale.

Strategy
Useful tactics include spreading them in an arc around the team so that they ignite one another in sequence; placing them in choke points and firing them off in front of attackers; and planting them near the two extraction points and igniting them to block pursuing Infected as the team bugs out. You can also throw the fireworks and ignite them while the Horde is attracted to Bile Bombs and Pipe Bombs to give you enough time to set up the boxes.
