Venture to the “Pier of the Unknown”!

Announced at the Showcase, Pier of the Unknown is an upcoming DLC expansion for Cassette Beasts. What is this all about? You’ll have to just wait and see…

Cassette Beasts Soundtrack: Physical Release!

You’ve asked for it! We’ve partnered with Black Screen Records for a physical release of the Cassette Beasts soundtrack by Joel Baylis! With both a 2-disc vinyl and a cassette tape release (of course!) this is an awesome way to enjoy the bangin’ tunes of Cassette Beasts! You can preorder these releases here:


We’ve had a lot of requests for monster plushes, so we’re happy to announce we’re working with the cool folks at Symbiote Studios on a line of Cassette Beasts plushes! On the Showcase, we showed a sneak peek at the Pombomb plush. We can’t wait for these – we’ll keep the community updated on what other monsters will be available, and when they’ll be available to preorder!

Wow, that’s a whole lot of stuff, huh? There’s a lot of cool stuff happening with Cassette Beasts, and we wouldn’t be able to do it without the continued support and enthusiasm from our community.

We couldn’t be more excited to share this experience with you all; it would help us immensely to wishlist and spread the word with your friends!

Fusion System Highlight & New Gameplay Showcase Trailer

In our last Steam Blog we talked about the in-depth fusion system, a powerful game system that allows you to fuse two different monster forms into a unique fully-animated sprite combination. This system can generate over fourteen thousand unique fusions that will allow you as a player to fully customize your team to fit your unique style!

As part of the Guerrilla Collective digital games showcase we now have more details and new gameplay footage to share!

Go Down Swinging

Hey folks! This week we’re showing off another new monster from Cassette Beasts!

Southpaw has a mean left hook!

Southpaw is a fast-moving, fast punching metal-type beast. Their bodies are coated with a lightweight and flexible metal that allow them to withstand attacks and deliver swift attacks. Unlike Palangolin, which use heavy armour plating and long-range weapons to fight, transforming into Southpaw gives you a lightweight and aggressive form that allows for a more agile approach to battle.

It makes you wonder: what if Palangolin and Southpaw fused in battle?

Combine your powers to become Palanpaw!

While most of the monsters in Cassette Beasts are designed in-house at Bytten Studio, Southpaw was designed for us by character artist Sami Briggs (Smai). Sami has drawn some really cool art for the project, and Southpaw’s pixel art sprite was drawn based on her initial concept below:

When asked about her thoughts when designing Southpaw, Sami said:
“I love creating things that look cool, sharp and sometimes exaggerated, so I really wanted to design a beast that represents my style and tastes! I felt a half-wolf, half-robot boxer would be an interesting combo that best reflected what I was after!”

That’s all from us for now! You can follow us for more news on our Twitter page, and you can do the same for Sami if you’d like to see more of her work. Don’t forget, you can wishlist Cassette Beasts on Steam!

Cassette Beasts Quarterly Wrap Up #1

Hey everyone! It’s been 3 months since we announced Cassette Beasts so we thought it’d be nice to do a catch up of everything we’ve revealed since then – and maybe show off some new stuff as well!

Our announcement trailer reveal in May went down better than we could possibly have imagined:

  • Over 100,000 combined views across Youtube and Twitter
  • Over a dozen press articles including PCGamer and Kotaku
  • A bunch of new Discord community members, now 500+ strong!

Along with the trailer, we also showed off some monster designs, a look into the game’s chemistry system, and also the fusion system. Our in-browser playable fusion demo also let players see for themselves the capabilities of our fusion system!

It’s been fun seeing fans discuss their favourite monster fusions!

Since the reveal, we’ve been showing off snippets of the game alongside working hard on it:

Our reveal trailer song, Same Old Story, was also announced as a part of Black Screen Record’s free compilation vinyl “Sounds of Summer 2020”. It’s really exciting to see our composer Joel’s work alongside other talented musicians – it’s totally free to order the record so you should totally do that!

As a little celebration for our quarter-year anniversary, we thought we’d show off some new monsters!

Carniviper and Dominoth

Carniviper may exude a friendly demeanour, but don’t let its smile fool you – it isn’t particularly welcoming. If these poison-type beasts are encountered in the grasslands of New Wirral, they are known to silently watch any passing humans intently until they leave their vicinity. If not, they’ll become hostile very quickly! You may also have seen Carniviper’s evolved form before.

Dominoths can flap their large wings to take flight, and also whip up gusts of wind to attack their foes. Rumours are that recording this air-type creature uniquely gives the one who recorded it the power to summon wings of their own… That can’t be true, can it?

That’s all for now! Thanks for joining us on this journey so far, it’s been great fun! There’s lots of cool stuff involving Cassette Beasts we can’t wait to talk about, so keep an eye on our Twitter page. As always, feel free to come by the Discord and chat to us!

We hope you’re keeping safe this summer!

Harbourtown Outskirts

New Wirral’s rangers keep this gate locked to keep monsters out of Harbourtown. But it’s been fairly quiet for a few days now!


On an unrelated note, we’ve teamed up with Black Screen Records on their free vinyl Sounds of Summer 2020. You’ll be able to listen to the full version our Cassette Beasts reveal trailer song “Same Old Story,” along with 13 other indie game tracks!

Cassette Beasts

Hi folks! It’s Tom and Jay of Bytten Studio here! You might have seen our previous release as a studio: Lenna’s Inception–a procedurally-generated action-adventure RPG, with a branching narrative and two complete art styles. Other games we’ve worked on include Stardew Valley, Starbound and Wargroove!

Today we’re revealing our new project: Cassette Beasts. This has been in the works since late last year–keeping it quiet all this time has been quite a challenge to say the least! So without further ado…

Grab your cassette player, it’s time to transform!

Collect awesome monster forms to use during turn-based battles in our indie open-world RPG. Combine any two monster forms using Cassette Beasts’ Fusion System to create unique and powerful new ones!

Welcome to New Wirral, a remote island inhabited by creatures you’ve only dreamed of, nightmares you hopefully haven’t, and a cast of brave folks who use cassette tapes to transform for battle. To find a way home you’ll need to explore every inch of the island, and record monsters to tape to gain their abilities!

Transform into monsters using… retro cassette tapes?!
Faced with the constant threat of monster attacks, the residents of Harbourtown, New Wirral choose to fight fire with fire. Record a monster to tape, then play it back to take on its form for battle!

Fuse monster forms
Getting close to your companion has benefits–while transformed you can combine your strengths to gain the upper handle in battle! Any two monster forms can be fused to produce unique, fully-animated new fusion forms.

Explore a rich open world
Certain monster abilities can be used in human form. You’ll need these to help you get around, solve puzzles, and locate dungeons. Glide, fly, swim, climb, dash, go invisible, or turn magnetic!

Travel alongside a diverse cast of human companions
Never fight alone! Form bonds, spend time together, and help your selected partner complete personal goals to become a better team. The strength of your relationship determines how well you’re able to fuse!

Master a deep battle system
Take advantage of elemental chemistry to apply extra buffs or debuffs alongside your attack, or even alter your opponent’s elemental type!

🌟 Coming to Windows & Linux! Consoles TBC 🌟
Price & Release Date: TBA

Cassette Beasts is something of a dream game for us. We can’t wait to share it with you all! 🙂

We’re currently looking for funding and publishing partners. If you’re as excited about Cassette Beasts as we are, you can help spread the word by sharing this post!

PS. For anyone wondering if this announcement changes it–the 1.1 update we announced for Lenna’s Inception is still on the way.
