UNYIELDER News

Welcome to EREBUS, a devastated land hiding many mysteries. To understand more about the world of UNYIELDER, it’s time to deep dive into the factions that shaped it. Some are already gone, but what remains can be felt in the current battles. Others are still here, in a different shape.

Let’s start with the TENNULI:

The TENNULI represent a few groups of Tribes that create fuel by grinding rust from the remnants of old skyscrapers into fine powder. This creates an aerosolised dust fuel that is used to power generators, machinery, and Vulcans.

Sent by the WORLD GOVERNMENT for the pneuma war, the Tennuli prioritize war and fighting. When the blackout occurs, they are left stranded in Erebus with all support cut off. Hence, they can only survive the way they know how - fighting their way through everything else.

Don’t miss out on our following intel about EREBUS’ factions!

Welcome to another INTEL: this time, we’ll explore the sounds of EREBUS. And what makes UNYIELDER so unique: ambient sounds, but also what contributes to the identity of the weapons, the cries of the tormented bosses, and the WOOSH of the desperate dash before the ultimate fall in front of a stronger enemy.



For this first episode, meet Viraj Ramsharan, the sound engineer artist behind the Bismarck’s pleasing sound of destruction.

“The lore of this weapon made it such an interesting weapon to design for. It's one that has been plucked from history, stripped straight off a battleship and slung onto the players shoulder for the ultimate mixture of decimation and power…

When creating the sound for the Bismarck, I wanted the player to really feel the weight and grandeur this weapon offers. One of my favourite things to do with weapons (especially bigger weapons) is to create a rhythm - here there's the initial firing mechanism of the shell propelling for which I used a metal impact, then a brief punchy burst sound followed by the thunderous tail - I used some explosion layers in both of them.

The team at TrueWorld have done a truly amazing job at designing incredible assets and giving us such detailed references to work alongside that really sparked our creativity!

In the ruined world of EREBUS, survival is about your skills and weapons. Once you beat a major boss, they might drop random perks in their lootbox and they can be game-changing, with the right combination.

To unlock superior Tiers drop chance, you'll have to explore the Mastery Tree and spend your available points.

The third composer is Hazel Ho, a musician from Singapore, who graduated Summa Cum Laude in Contemporary Writing and Production from the prestigious Berklee College of Music in 2023. The heart of her art lies in live instruments, with rather avant-garde jazz inspirations.



For UNYIELDER and TrueWorld Studios, she stepped away from her usual genre to draw inspirations from rock, metal, and distorted, glitchy production techniques, perhaps marking a new era for Hazel Ho. She handled the themes for SKINNER and PRETENDER. She drew from the roots of Andalusian music to bring her melody: “I was diving into the flamenco genre for SKINNER's theme, so the first few iterations were very flamenco-driven. Imagine: Cajon, castanets, flamenco Guitar, orchestral elements, with Andalusian cadences. No rock or metal elements yet. The reactions were hilarious - the meeting room burst into laughter over this direction for SKINNER (in a good way!), and people were even starting to think about adding cactuses in the arena. I later on added those rock/metal elements to up the aggressiveness! PRETENDER's track has a touch of a bassline in 5/8 in one section that I love! Can't help myself with odd meters sometimes! Also, this entire track is a big step into the production realm for me personally!”

And that’s all from our maestros of chaos! Stay tuned for our next instalment as we speak to the sound designers of Pitstop - the ones who created the satisfying rat-at-tats of the guns!
