About this Demo

We began our journey a year ago as a small indie team from Switzerland. Driven by curiosity, creativity and a lot of caffeine. Now we’ve reached our first big milestone with the Steam Next Fest. We proudly present Darkest Cube, a roguelike deck-builder that is inspired by Slay the Spire and Dark Souls. But this is just the beginning. Our upcoming Kickstarter campaign will help us bring the full vision of Darkest Cube to life.

What is special about our Game?

1. True Deckbuilding at its Core
In Darkest Cube, copying a deck list from the internet won’t save you — every run begins with a unique seed, generating new relics, cards, and enemies each time. Strategy is everything: study your upcoming foes and adapt your deck to counter their strengths. Every card matters — even one you haven’t used for hours might become the key to survival. And don’t stick to just one archetype; sometimes, success means shifting from defensive to offensive or experimenting with effect-heavy builds. Adapt or perish.

2. Constantly Changing Challenges - the Dark Cubes
Inside the Dark Cubes, conditions change quickly. Enemies alter their attack patterns and abilities from floor to floor, making every run unpredictable. Mastering the balance between your Skill Tree, Relics, and Deck composition is essential. Adapt or perish isn’t just a phrase - it’s the core of the experience. To empower players, we reintroduced the Side Deck: a strategic tool that lets you adjust your deck when needed, instead of being entirely dependent on random card rewards like in other games. It puts control back in your hands and rewards smart adaptation. But can you survive the Darkest Cube?

3. Co-op Mode on the Horizon
We believe there are too few good co-op experiences — games that truly connect and challenge friends together. In the niche of roguelike deck-builders (only around 800 titles exist), almost none explore cooperative gameplay. We want to change that. Team up with friends, face even greater challenges, and discover new synergies between decks across over 60 cards per class — with five unique classes planned.

4. A Draft Mode Worth Waiting For
We’re keeping this one secret... for now. Let’s just say: it will surprise you.
