Halifax has been played entirely online. These resources are based on online play although not all resources are for online play only.
Virtual Environment Online Play Free
If you want to play online with friends, Roll20 does a great job at creating a virtual environment to run a tabletop RPG campaign.
Roll20 is free outside the box. However, you can expand upon its functionality through the Roll20 Marketplace.
Roll20 Marketplace Add-on
I use the Alien RPG Starter Set which Free League Publishing put together themselves. What I like best is that it acts as a player handbook.
Complete conversion of the fast and effective version of the ALIEN RPG Ruleset as searchable handouts
A complete Cinematic scenario, "Chariot of the Gods" by sci-fi novelist Andrew E.C. Gaska
Full floor plans for the scenario, featuring Dynamic Lighting (plus/pro feature)
Five pre-generated characters, plus character sheets for all additional playable NPC's
Full color map of chartered space in the year 2183
Game marker tokens for keeping track of characters, motion tracker pings, and more
Card decks for keeping track of weapons, personal agendas, NPCs, and combat initiative
Rollable tokens featuring the custom ALIEN RPG Base Dice and Stress Dice
Roll20 Marketplace Add-on
This add-on gives you the tools to create a creepy environment that works well with Alien RPG. I have used it to create a couple of space stations in my Halifax homebrew campaign.
Animated Assets living character tokens, Active locations and Interactive map features
Custom Audio Use the included soundscapes to add another layer of immersion to your sessions
Pre Built Maps the pack includes several maps already built to help you dive in straight away, or practice building your own maps.
Dynamic lighting pre built dynamically lit maps and characters (subscribing users)
Fully Modular mapping tiles Seamless map tiles enable you to create your own star ship interiors using corridors, rooms and vents.
Cinematic assets Don't just throw bad guys at the enemy, use the scene based animations to create memorable moments in your story!
Roll20 Marketplace Add-on
I found Dark Colony to be extremely useful for creating a colony. There are multiple packages (four at the time of I wrote this) that you can purchase. I have and use them all.
Book PDF Required
You'll need the core rulebook first and foremost. When you buy the book, you will also receive a PDF of the book. I use the PDF during sessions because I like the ability to search for keywords to find answers quickly.
Tools Sets Tokens
Free League published an article that offers free and paid content. You'll find tools, sets and tokens. I use the tokens for the Halifax campaign.
Name Generator Free
This website is awesome for naming your NPC's, planets, stars and just about anything else.
Music Free
I searched for music that I could resonate with and provide the environmental sound I was looking for. Darren delivers where no one else I found could. He has music that fits every scenario.
Writing Organization Free
I tried a few word processing and story building applications. Either they were more than I needed or not enough and some were expensive.
I settled with Google Docs. If you insert a table to contents and use headers, Google Docs works great for writing a campaign and organizing content.
Spreadsheet Organization Free
This is were I keep track of planets, people, equipment and various other bits of information. Sorting alphabetically helps a lot.
You can create multiple sheets in one file by using the tabs at the bottom. This is helpful for organizing similar content.
Generator Tool
Generate star systems, planets, and colonies with the click of a button. Modifiers are already in place so there is less work on your part.
Halifax is a space truckers campaign which means my players visit a lot of planets. I needed a quick fix for generating planets so I built the star system generator.
Flowchart Tool
Combat in Alien RPG is quite different than any tabletop RPG that I have played. In Halifax, combat does not occur often so I often find myself unprepared for combat even when I think I am. This flow chart helped me alleviate a lot of pain.

Information Tool
A few questions kept coming up during the Halifax campaign so I created this compendium to help my players.
Some of the information includes talents, governments, corporations, combat, and more.
Information Tool
I often forgot about the general talents during my campaign. My players forgot about them, too. I created this document to help us all remember that general talents exist and these are what you have to choose from.
Information Support
There are two communities that I felt were helpful. Alien RPG by Free League on Facebook and r/alienrpg on Reddit. Both communities are supportive, informative, and engaging. There are plenty of communities to choose from but these two worked best for me.
