Alien RPG - Starter guide

What is the Alien RPG?

The Alien RPG puts you aboard a doomed ship, colony, or station in the world of the Alien films, facing the corporation that runs it and the xenomorphs it should never have brought aboard. It plays in two distinct modes: Cinematic, built for a single deadly session with pre-generated characters who are not expected to all survive, and Campaign, built for a longer story of corporate exploitation and slow-burning dread.

Free League Publishing first released the game in 2019, and it won a gold ENNIE for Best Game the following year. The Evolved Edition is the second edition, funded through a 2025 Kickstarter that raised over 2.5 million dollars, with the Core Rulebook releasing that November. It is fully compatible with existing first-edition material, and the most visible change is a full art and layout overhaul by Johan Nohr, the designer behind Mörk Borg's distinctive look. Underneath, the rules have been streamlined based on years of player feedback, with a new Life Path character creation system and an added solo mode.

How does the system work?

The Alien RPG runs on Free League's Year Zero Engine: roll a pool of six-sided dice equal to your attribute plus skill, and every 6 is a success. When a roll fails, you can push it for a reroll, but pushing adds Stress Dice to your pool, yellow dice that also succeed on a 6 but panic you if they land on a 1. Stress makes you sharper and more dangerous right up until it makes you a liability.

The Evolved Edition softens that spiral with Resolve, a new value calculated from Wits and Empathy. When a Panic Roll is triggered, you roll a d6, add your Stress Level, and subtract Resolve, meaning seasoned characters hold themselves together longer than raw recruits before a bad result forces a debilitating condition. Combat has also been reworked around Full and Quick actions, giving you a real choice each turn between doing more or staying ready to react. Character creation now runs through a Life Path system, tracing a character through formative events like corporate betrayals or military postings that hand out Talents and built-in Stress Triggers, so no two survivors start the story the same way.

What do you need to start?

The Evolved Edition Starter Set is the fastest way in: an abridged rules booklet, five pre-generated characters with individual secret agendas, an expanded version of the fan-favorite scenario Hope's Last Day set at the Hadley's Hope colony, a double-sided map, cards for gear and initiative, tokens, and a supply dial for tracking air and ammunition. It needs nothing else at the table.

The Core Rulebook is the full game: complete rules for both Cinematic and Campaign play, the Tartarus Sector campaign setting, zero-gravity and miniature-scale rules, and Last Survivor, a new solo mode designed by Shawn Tomkin of Ironsworn fame and Matt Click of The Mecha Hack. Groups planning a long campaign, or anyone wanting to play solo, will want this over the Starter Set.

Who is this game for?

The Alien RPG is for groups who want tense, high-stakes survival horror where death is a real and expected outcome, not a rare edge case. If your table enjoys the slow tightening of dread, the temptation to push one more roll despite the risk, and stories where the corporation is as dangerous as the monster, this delivers exactly that.

It is a poor fit for players who want their characters to reliably win or grow into heroes over a long campaign; the tone resists that kind of power fantasy by design. And if a table finds permanent character death upsetting rather than exciting, Cinematic mode in particular is built to produce it often.

How does it compare to other systems?

Against Dungeons & Dragons 5e, the contrast is stark: D&D characters are built to become more powerful and more capable of surviving danger, while Alien RPG characters start fragile and stay that way, with Stress actively working against them the longer a scene runs.

Within Free League's own catalog, the closer cousin is Vaesen, since both run on the Year Zero Engine's six-sided dice pools. But Vaesen's horror is folkloric and investigative, giving players room to negotiate with a threat, while the Alien RPG's Stress and Panic system is built for a much faster, more physical kind of dread, where hiding and running matter more than talking. And if the new white-page, high-contrast layout catches your eye, that is Johan Nohr's design work, the same artist behind Mörk Borg's look, though the two games could not play more differently.

Where do you start?

Run the Starter Set's Hope's Last Day scenario first, using the five pregenerated characters. It is built specifically to teach the Evolved Edition's mechanics inside a self-contained, three-act story, and it gives new players an immediate sense of what Stress and Panic feel like at the table.

One piece of advice for the Game Mother, as the GM is called here: resist rolling dice constantly. The rules work best when checks are saved for moments that are genuinely dangerous, since every unnecessary roll is one more chance for Stress to spiral out of control before it matters.
