Zineshot #1: Serum
Zineshot #1: Serum
Every Dungeon Master knows the feeling. You buy a one-shot. Twenty pages later, you know everything about the local economy, the political tensions between three forgotten kingdoms, and the childhood of an NPC the players will probably never meet. But what the adventure is actually about? No idea.
Our Zineshots solve that problem. No endless lore. No hours of preparation. No homework. Just a complete session, ready to play.
In Serum, the players are given a simple yet terrifying objective: survive the night.
That very evening, an ancient tomb has been breached. Since then, the dead walk the land once more. With every passing minute, their numbers grow, and unless someone intervenes, the entire region will be overrun by the undead by sunrise.
To seal the tomb once again, the players must gather clues, help survivors, and discover what truly happened. But time is scarce. Not every side path can be explored. Not everyone can be saved.
As the night grows darker and the zombies press closer, the players must decide what matters most: their mission, their own survival, or the people who need their help.
Like every Zineshot, Serum contains everything you need for a full evening of Dungeons & Dragons.

An amazing one-shot that i once played as a player i am now ready to DM for my party. A perfect mix between all the things that make ttrpg so fun!
This one shot gives more than expected. A physical zine optional digital downloads ready to use content and responsive support. It feels like a complete package that respects both players and the Dungeon Master. I will definitely buy more.
I appreciate how flexible the adventure is. It is written for level two characters but it is very easy to adjust. We ran it with a mixed group and it still worked perfectly. The balance between structure and freedom is excellent.
The delivery was incredibly fast and the zine arrived in perfect condition. No bent corners no damage at all. You can tell that it was packaged with care.
I downloaded the extra maps and handouts right after purchase. Having printable versions ready made preparation effortless. The material for the Dungeon Master saved me hours and that is a big advantage for spontaneous games.

Prachtig.
Ik ga wel het einde aanpassen voor de tere kinderzieltjes (ze zijn 12).
A little gem
Very funny and complete adventure, it's the most fun I've ever had running a pre-written one shot. The party was very amused as well and stunned by the props that came with the adventure. The mini's in the package are awesome and very helpful too.
Its great
Great D&D night with this one-shot! Amazing :)
Ordered the Zineshot Anthology (excellent oneshots that I hope to implement in my Acquisitions Incorporated campaign) and very happy with what I got. Booklets look good, illustrations are light and uplifting and the adventures themselves are great. Shipment was lightning fast, I got my order the day after purchase. Will definitely return!
Great accessory for DND!
The atmosphere is excellent and the mystery slowly unfolds in a satisfying way. It requires a bit of guidance from the Dungeon Master, but the payoff is worth it.
I'm loving the design, it's exactly what I needed!
Also, look at that goldfoil cover, I love it!
The adventure leaves enough room for improvisation. A few scenes are written loosely, which I enjoyed because it let me tailor the tone to my group. Others might prefer more structure.
I hope more styles come out in the future. I am close to finishing this one and I want the next to look different because I will definitely keep using these.
It handles ink, pencil and markers without issue. I erase constantly and the paper still looks fresh after multiple revisions.
The story is dark and unusual, with moments that genuinely surprised my group. It is not overly complex, which makes it easy to run, but still full of eerie detail.
