The Guns N' Roses legend has once again composed a new, original score for the hit Scarecrow haunted house, while he'll be bringing out a sequel to last year's SLASH: Music of Universal Studios Hollywood – Halloween Horror Nights album.
The theme park is introducing a Slash bar at Jurassic Cover close to the Jurassic World ride with a range of themed cocktails.
As well as Danse of the Dead and Beautiful Dangerous, guests can also enjoy the non-alcoholic Slash's Snakepit.
For food, they'll be able to tuck into his favourite Chicken Satay, Thai Beef and Thai Curry Tacos, with a Hat Cake appropriately on the menu as a dessert styled on his iconic top hat.
Meanwhile, a scare-actor will be on hand to spook guests in the bar, sporting a black curly wig and top hat on stilts as a ghoulish version of the Welcome To The Jungle guitarist.
Other themes for this year's Halloween Horror Nights include haunted house based on Friday the 13th slasher favourite Jason, Amazon Prime Video's Fallout series and Terrifier's Art The Clown killer.
Meanwhile, there have been reports from Fightful Select and other outlets that WWE is set to announce its own involvement in the annual event.
It's believed that the Wyatt Sicks group - which includes sinister characters inspired by late WWE legend Bray Wyatt's creations - will be heavily featured.
Halloween Horror Nights will run at Universal Studios on select nights between August 29 and November 2.
