Behaviour Interactive Inc., Canada’s largest game developer and publisher, has launched the PTB (Public Test Build) for the new original chapter “Dead by Daylight: Sinister Grace” for the
asymmetrical multiplayer horror game “Dead by Daylight” on Steam starting Thursday, September 4, 2025. Inspired by ancient Thai folklore, this Chapter introduces a new killer, “The Krasue,” and a new survivor, “Vee Boonyasak,” immersing players in a spooky world. Both characters share a deep passion for music, which shapes the story and is an integral part of this new chapter. This Chapter also introduces six unique perks, enabling a variety of playstyles. The “Hex” perk, introduced for the first time since the “Dead by Daylight: Castlevania” Chapter, brings new tactics and tension to both Killers and Survivors. Taking inspiration from ancient Thai folk tales, we take on a new style of horror. “Dead by Daylight has had many memorable collaborations with horror classics, but this Chapter holds a special significance. Creating an entirely original Chapter allows us to explore fresh themes from countless horror subgenres. This time, we looked to Thai folklore for a new take on horror. Gasu is one of the most feared creatures in Thai culture, with a macabre origin and a grotesque, intense appearance. Of all the Killers that have appeared in Dead by Daylight to date, this one will likely be viewed as a particularly impactful and innovative character. Dave Richard, Senior Creative Director for Dead by Daylight, had this to say about this Chapter: “In creating this chapter, I wanted to create something that would please anyone with a taste for gore. Gasu’s transformation is emblematic of that, and I used intense visuals to depict her body cracking and peeling under the pressure. The transformation from a beautiful woman with an angelic voice into a macabre monster, dangling organs and dripping blood, like something out of a nightmare, creates a powerful contrast. It’s this contrast that will captivate the viewer, leaving a lingering, eerie feeling and drawing intense interest in the story she has walked so far.” Once you see it, you’ll never forget it… A macabre figure that leaves a strong impact burned into your mind Gasu is a floating, severed head monster that appears in the appearance of a young, seductive woman. When she transforms into a severed head, she floats up, her internal organs dangling, like a balloon floating on a string. To satisfy her insatiable hunger, she detaches herself from her host’s body and sets out nightly to hunt prey. Gasu, who appears in Dead by Daylight, was originally Burong Sukapat, a promising opera singer. She possessed a beautiful voice to match her beauty, but one day, she was approached with a shady deal and accepted the offer for fame. In exchange, she was forced to allow “something” to reside within her body, and Gassu’s curse began… When playing as Gasu, you can switch between two forms: a “decapitated head” and a “human” and enjoy different hunting methods. In his floating decapitated head form, he gains increased movement speed and can unleash the “Intestinal Whip,” a melee attack that swings his intestines like a whip. Meanwhile, in his human form, he spits out a projectile called a “Leeching Gland,” which infects any survivors it hits and reduces their attack resistance. By switching between these two forms depending on the situation, players can deploy a wide range of tactics, and especially experienced players will have high killer potential. Vee Boonyasak, an energetic drummer who loves music Broken amps, sweaty live music venues, dilapidated cars… All of these things give me a sense of being alive. -Vee Boonyasak Vee Boonyasak, drummer and central figure in the band Axekick, is willing to work tirelessly for her music. Her grueling tour across Thailand in an old car also strengthened her mental health. While the band’s invitation to the misty forest was a complete misfortune, it sparked worldwide buzz and record-breaking streaming numbers. Vee is a breath of fresh air to the already impressive Dead by Daylight roster, bringing captivating brightness and energy to the band. With a park and playing style that embodies the spirit of rock, her participation will have the impact of a powerful drum solo. Dave Richard had this to say about Vee: “We’ve had so much fun bringing musicians to the Misty Forest, and we’ve got enough characters to form a whole band. As a drummer myself, Vee is special to me. I’m thrilled to tell her story and see her unique energy be incorporated into the world of Dead by Daylight.” Dead by Daylight: Sinister “Grace” will be playable for a limited time on Steam starting today, Thursday, September 4th, 2025 at midnight.
