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.

To create the meta that will suit you, in addition to the weapon attachments that are randomized: you'll have to be patient and you'll have to make the right decisions before EREBUS and its bosses catch you up.
