TomeHaven is a PDF and EPUB reader made specifically for tabletop roleplaying game players, and for anyone who wants to proudly show off their collection. It displays your books beautifully, helps you organise and find them, and lets you read them smoothly and sharply. Players can organise their books into collections and sections, spread them across multiple bookcases, and choose themes from warm wooden shelves to glowing sci-fi displays. A Reading Room keeps open books together, ready to pick up where the last session ended. The reader is custom built for large, art-heavy RPG PDFs. Tabs keep several books open at once, making it easy to move between a core rulebook, an adventure and a supplement during play. Search, bookmarks, highlights, notes and two-page views help players find and keep track of what they need. For frequently used rules, TomeHaven’s binders collect cut-outs from PDF pages alongside written notes. Tables, spells, stat blocks and campaign reminders can sit together, with picture cards linking back to their original book and page. The library and reader are free. An optional TomeHaven Pro subscription adds more binders, more bookcase themes and shelf customisation, search across the whole library, home-screen widgets and expanded reading statistics. No account is needed, there are no ads, and TomeHaven doesn’t upload players’ books. TomeHaven is made by KodaWorks. The screenshots show a fictional demo library with openly licensed, human-made artwork. See store page art credits for art credits.

DexArcana is a set of free browser tools for Dungeon Masters, so there's nothing to install. Its Dungeon Master Screen keeps turn order, fog, dice rolls, notes and cue cards on one page during a session, and players don't see the Dungeon Master's notes. The screen also has a dice tray with d4 to d100, plus advantage and disadvantage on the d20, and encounter tables under Extras: roll one and the monster or NPC drops straight onto the open map. A soundboard and ambience layers are there too. The map builder lets a Dungeon Master lay down floors, walls, furniture and lighting to make a battle map without drawing skills. Fog and lights decide what players see, and maps can be exported as PNG or JSON. The world notebook links lore entries so places, people and factions stay connected. Players join from their own Player Screen, where they keep their sheet, the party list, chat and dice. Players need a free account to join. Every tool is free on every plan. Paid plans only add saving space: Dungeon Master is $5 a month and Guild is $12 a month. The free plan needs no card. It works for in-person tables using a second screen and for online games.

Mothership is an action-packed mixture of sci-fi and horror themes, combined into a streamlined gaming system about surviving in the cold, deadly vacuum of space while everything around you is trying to kill you. All at the same time as you are fighting (or fleeing from) alien creatures who aren't there to make any new friends. Chaos. It was published by Tuesday Knight Games and released in 2024.  It is a survival horror system designed for one-shots and campaigns, inspired by classics like Alien, Event Horizon, and Pandorum. Famous for its streamlined ruleset and award-winning graphic design that prioritizes ease of use at the table. The game, at the same time simplistic and streamlined in design, will challenge the characters at all times, allowing the game to focus on the storytelling and less on having complicated rules. The system it is inspired by is Old School Renaissance Description In Mothership, players take on the roles of blue collar workers in space, such as Teamsters, Scientists, Androids, and Marines. You are not powerful or heroic soldiers; you are vulnerable humans trapped in high pressure environments with alien monsters, failing life support systems and the crushing weight of corporate greed. The game is designed to be fast-paced and unforgiving, where the primary goal is not to win, but often enough - to survive. System Overview & Key Features d100 Percentile Resolution In the core of the game system is the d100 percentile system. Roll two d10 dice and get a number from 00 to 99. Success means rolling a lower result than your character's appropriate stat or skill for the task. Rolling a double, like 11, 22, or 33, is considered a critical success if it succeeds or a critical failure if it fails. Rolling low is the target for survival. Stress and Panic As characters encounter horrors or suffer trauma, they accumulate Stress. When a character experiences a terrifying event or rolls a critical failure they must make a Panic Check. The more Stress they have, the more likely they are to suffer a catastrophic mental breakdown, ranging from a heart attack to a violent psychotic break. The Save System Instead of a long list of saving throws, characters have four primary Saves: Sanity, Fear, Body, and Armor. These are used to resist different types of potential trauma. Fear saves are rolled to keep your cool under pressure, while Sanity saves represent your ability to process alien truths without losing your mind (think lovecraftian horrors). Class Based Skills The game features four distinct classes. Marines are obviously combat focused, Teamsters are pilots and laborers, Scientists are experts in medicine and biology, and Androids are cold calculating, yet efficient machines. Each class has it's unique starting stats and specific triggers for when they gain or lose Stress, which is based on their personality. Lethal Combat and Healing Combat is extremely dangerous and often a last resort. Weapons are likely to deal potentially excessive damage when compared to a character's total healthpool. Healing will be slow and require resources that are hard to come by in the middle of the constant crisis, making every injury feel like a significant threat to the character's chances of making it out alive. Deadly Ship-to-Ship Combat The game includes a streamlined system for starship encounters. Ships have their own stats and modules that are likely to be damaged during a fight. Players must work together to manage various roles and stations, like Engineering or Piloting, to keep the ship's hull from breaching while under fire or fleeing from cosmic anomalies.

Red is a generic role-playing game system designed to bring your creativity to life across a variety of settings and genres. With mechanics adapted from Wretched, Red is easy to pick up for those already familiar with our games, yet distinct in its approach, breaking free from the anti-heroic roots of its predecessor. Red invites you to explore a broader spectrum of characters—heroes, villains, or somewhere in between.  Unlike Wretched, it exists outside the Wretchedverse continuity, leaving the aesthetic and narrative choices in the hands of players and Game Masters to build their unique worlds. The system retains enough compatibility to integrate with existing OSR materials, while simplifying rules for faster, deadlier combat and more versatile character progression.
