The Pattern Boomer is a craftable, giant mortar-style firework available for players to purchase from the in-game Permanent RUST store added during the Season’s Beatings! Event in December of 2021.
Facepunch implemented fireworks into RUST during the Lunar New Year update on January 24th, 2020.
Unlike other firework varieties in-game, the pattern boomer is the first of its kind to have a deployable artistic feature incorporated into its use. Players that deploy and interact with the pattern boomer once it’s on the ground will have the opportunity to paint a picture that will be transcribed to the sky once the firework is lit via Torch strike or Igniter. Players may also save their designs for use on other fireworks later.
Or, if you are not interested in raiding other players, fireworks make an excellent way to dump your overproduced Charcoal and gathered Sulfur.
Most players appreciate firework shows and understand that your base is unlikely to have much sulfur in stock by seeing your fireworks, making your base an undesirable raid target.
Due to too many fireworks launching at once affecting lower-end systems, Facepunch implemented a limit on the number of fireworks launching at once. Servers now queue all active Firework launchers.
