From haunted houses that can raise the scream-o-meter to 11, to spooky dance parties perfect for those wearing sexy succubus outfits, to milder family-friendly events, there is something for everyone.
The second edition of the Singapore Halloween Festival, held at Downtown East this year, will feature a Monster's Ball dance party, a zombie maze challenge and Singapore's first Halloween run at a water park.
The entertainment hub also has a virtual-reality experience, where guests can immerse themselves in four scenarios, such as a zombie apocalypse or a mission through the underworld.
Downtown East's general manager, Mr Ronnie Tan, says that about 2,000 thrill seekers attended its Halloween events last year.
He adds: "Downtown East has always refreshed our offerings to ensure that the thrills continue to excite our guests. Singaporeans are still looking for creative and fun ways to celebrate Halloween."
In response to this demand, malls, nightspots, and businesses are also gearing up with their own Halloween-related activities.
With the scene getting more crowded in recent years, even Halloween Horror Nights, which many say is the premier event of the season, is upping the ante.
The event, which does not reveal attendance figures, will feature five haunted houses, two scare zones and two live shows.
This year, close to 500 scare actors are involved - up from 280 in the first edition in 2011 - and they will take on roles such as zombies, ancient Chinese empresses and witch doctors.
Guests can also expect more cutting-edge technology, science, stagecraft and daring stunts in this year's edition, adds Mr Horkin.
Observers say it is the event's constant renewal and fresh programming that set it apart from most other Halloween events here.
Ms Sheila Sim, 46, a senior lecturer at Temasek Polytechnic for its leisure and events management diploma programme, says: "Universal Studios Singapore has the resources and infrastructure to offer a unique and exciting product year after year.
"There will still be niche opportunities for other attractions, but Halloween Horror Nights is undoubtedly the most successful event of its genre in Singapore."
Mr Michael Chiam, 56, a senior tourism lecturer at Ngee Ann Polytechnic, says: "The space allocated to Halloween Horror Nights is larger than that of the other events in Singapore.
"This year's event also has more than seven attractive themes - each with a different fright level - and visitors are drawn to the thrill and excitement."
Business development executive Adeline Koh, 24, has been to Halloween Horror Nights three times - in 2012, 2013 and 2015 - and will most likely attend this year's edition too.
She says: "I always look forward to see the sets, props and make-up of the actors."
Events manager Jasmine Nera, 23, has not decided what to do, but will plan something with her friends soon.
She says: "I'm quite a party animal so I usually end up celebrating more at the clubs with my friends than anywhere else."
