Yet Another Zombie Survivors Soundtrack
Optional album DLC. Not a cheat pack. New in-game tracks join the album.
The Yet Another Zombie Survivors Soundtrack is paid extra audio, not a gameplay DLC. Steam lists it as app 4377470, released 19 March 2026, under Additional High-Quality Audio. GOG sells the same album. It does not include the base game. It does not unlock Ranger. It does not skip Training. Buy it if you want the horde themes on a train without launching Isolated City. Store discounts for the game itself stay on platforms and promo codes (there is still no redeem box).
The composers are Adam ‘Scorpik’ Skorupa, Krzysztof Wierzynkiewicz, and Michał Cielecki, credited as Music Imaginary. The studio points at their work on The Witcher series, Shadow Warrior 2, and Bulletstorm. That is liner-note context, not a gameplay buff. The files are MP3 and FLAC. Steam’s Music feature is the intended player: in the library, right-click the soundtrack app, Download Album, then Play Album or Browse Local Files for your own player.
What you hear in a run versus what you buy
The in-game mix is the loop you already own with 1.0. The DLC is the album export. The store text says additional music tracks added to the game later are also added to this soundtrack. 1.0 shipped new pieces into the client; owners of the March album should not need a second SKU for those extras. If a track is missing after a patch, verify the soundtrack app files the same way you verify the game.
Track titles on the public listing include Main Theme, The Horde is Coming, Let Them Come, Sands of Die, Tremors From Within, Moonlight March, Heavy Metal Witchcraft, Legacy of Rust, Death Clad in Iron, plus later names such as Cyberdeath, And Yet They Stand, and The Fire Within Us as the album grew. Treat the live store tracklist as truth. This wiki will not pretend a ripped YouTube mix is the DLC.
How this sits next to the rest of the wiki
Hardcore is not “a louder soundtrack.” It is a ten-minute mode: How to beat Hardcore. If you searched “YAZS OST” because the city theme is stuck in your head, this is the buy page. If you searched because a blog said the soundtrack unlocks Infinite, go to how to unlock Infinite instead.
Official doors remain Steam, Discord, and Trello on the Links Hub. Support mail is still support@awesomegamesstudio.com. Do not paste album files into a codes field that does not exist.
Price moves. Steam and GOG run their own widgets. Storage on GOG called out tens of megabytes for MP3 and extra hundreds for high-quality audio — believe the live requirements. Console storefronts sold 1.0 the game; do not assume every console SKU also sold this album on day one.
What this page will not do
We will not host FLAC files. We will not rank which map theme is “S tier.” We will not invent a 1.0.0c2 music hotfix that Steam never posted. When the studio adds another track to the DLC, the store listing updates first, then this paragraph.
After you buy
Download the album in Steam Music, then keep the game and the soundtrack as two library rows. Replacing in-game audio with the FLAC folder is not a supported option and will not raise your DPS. If 1.0 added a cue you cannot find in the album, verify both apps before you refund. Console players who only own the disc or download of the game may not see this SKU on the same storefront — that is a storefront gap, not a missing cheat.
Frequently Asked Questions
Quick answers to the most common questions.
Is the soundtrack required to play 1.0?
No. It is optional audio DLC. The game runs without it.
Where do I buy it?
Steam app 4377470 and GOG. Use Download Album in the Steam Music feature after purchase.
Do new 1.0 tracks cost extra if I already own the OST?
The store says future in-game tracks are added to this soundtrack. Verify files if something is missing after a patch.
Does the OST unlock anything in-game?
No survivors, modes, or Training. It is an album.
