Each era keeps its own map, pins, nested location maps and day-by-day timeline pins linked to cards and sessions. You can show the same city before the war and after it. - Templates & Packages: Every world is built on a template (D&D 5e is built in) and pulls content from packages. A package is a bundle of cards you can install into any world, link to other packages, or share on the marketplace. Custom templates are coming. - Codex: Schema-driven cards for NPCs, monsters, spells, items, locations and more. Every reference is a tappable link. Pin cards to the top, preview any card with a long press, and search by name, tag, category or text. - World Map: Pins, grid and scale, drawing, fog of war, and nested maps you can walk into (districts, dungeons, taverns). - Mind Map: An infinite canvas with linked nodes, workspaces, freehand drawing and undo/redo. /images/general-media/1791564252_TB7zwrCp.webp Running the Session - Second Screen: Give the table its own view. Pop out a window onto a second monitor, cast to a TV or projector, or project into every connected player's app. You choose how battle maps, images, cards and PDFs go out. Fog of war and hidden tokens stay hidden. - Battle Map: The session screen *is* the map, with the encounter panel and event log on top. It has layers, fog of war, AoE templates, 5e diagonal rules, creature-sized tokens, shapes and text, a DM-only layer, hidden tokens, movement trails for the round, and two maps joined into one. - Combat Tracker: Initiative, HP (with hit-dice rolls), conditions, turn order and an event log. - 3D Dice: Dice roll across the screen with named styles. Skills and saving throws roll from the character sheet with one tap. - Soundpad: Layered ambience with gapless loops, fades and ready-made soundpacks. - PDF Library: PDFs kept inside the world, opened in tabs and shareable with players. /images/general-media/1791564292_BnuuXJTS.webp Characters - Full 5e rules: Species, class, subclass, background and feats fold into one sheet. Each sense, resistance, proficiency, trait and always-prepared spell shows where it came from.

ASIs, feats, subclass and spell picks wait as pending choices. /images/general-media/1791564330_JBRRDNZ4.webp Playing Online - Online worlds: Put a world, package or character online and it stays the same on every device you sign in on.

Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents. Every character, faction, location, and event you create becomes a linked entity, so your world stays connected and explorable as it grows. Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

One Realm is an AI-assisted campaign workspace and virtual tabletop built for groups that want to play tomorrow—not spend the week preparing. It turns adventures, source material, and campaign notes into an organized, playable world, helping GMs complete work that might otherwise take hours or days in a matter of minutes. Characters, locations, encounters, maps, relationships, and story events are automatically organized and connected. From there, the GM can prepare scenes, create artwork, manage characters, and run the game through the integrated virtual tabletop. Because everything shares the same campaign context, preparation flows directly into play without rebuilding the session across multiple tools.

Thrive to Survive is a tabletop RPG ruleset for a modern day zombie apocalypse. Launched on Kickstarter in 2025, with decades in development this system gives rules both to make one of a kind custom survivors as unique as the player. And intense apocalypse campaigns and encounters for the game master. Combat The combat system for Thrive to Survive is based on the chaos of combat and how enemies react to each other while fighting rather than simple attacks and health pools. As characters get stronger they are able to use more combat maneuvers that manipulate how strikes land in combat and what they do to their enemy, after all in the end you have to destroy the head! While at some points you may want to build a wall to keep out the dead, other times you may need to break one down to escape a situation. Thrive to Survive gives rules for handling buildings, obstacles and construction so that every player can interact with the world how they see fit. Part of what makes a zombie apocalypse game so enticing is the realism of how a person would deal with an apocalypse. Keeping a fine balance of simple rules and realism allows for an easygoing and exciting adventure. Attributes There are an infinite number of ways someone can survive the zombie apocalypse. While the most common thoughts about surviving are how can you kill the most undead as possible, you have to think of thriving as well. From farming for your own food, Creating tools and equipment to help others, Medical knowledge to keep people alive, and even computer skills to access old data or create something new! To capture this the character creation gives you access to skills across the board, abilities your survivor possesses, and other features to make your survivor unique. Each survivor builds from the ground up by picking skills, talents, attributes, disabilities, features, and equipment. These sections are all connected in creating the gameplay of each survivor. Skills While there are a plethora of skills, most of them can be broken into a couple groups, Combat skills that determine your attacks such as the blade skill. Action skills that let you attempt something beyond the mundane such as acrobatics, and Crafting. Crafting allows you to design, build, repair and upgrade any item in Thrive to Survive. The more complex an item is the more time, material and skill is needed to create it. If you want to stick some nails through a baseball bat to cause some extra mayhem, you’ll need some training in weapons crafting. But if you want to hand craft a new design for a 50 caliber machine gun, you’re going to need some specialized skill and a lot of time. Crafting skills also build on each other, meaning that like in the string map shown here you have to have some skill in the previous crafting level in order to get the next. For example to become skilled in crafting explosives you will need a few levels of engineering first.
