Alien RPG: Dice & Strategy Guide

In space, no one can hear you fail a Stress roll. Here is how Free League’s dice-pool system works, why Stress is a double-edged sword, and how to keep your crew breathing.

The Alien roleplaying game, published by Free League, captures the dread of the films through a dice system that ties your competence directly to your fear. It runs on a pool of six-sided dice, and its cleverest twist is that the very thing which makes you roll more dice — Stress — is also the thing most likely to get you killed.

The dice and the core mechanic

The Alien RPG uses a pool of six-sided dice. To attempt something risky you gather a pool by adding the relevant attribute and skill, roll that many dice, and look for sixes. Each 6 is one success, and a single success is usually enough to succeed at the task — extra sixes give you a better, faster or more effective result (and matter a great deal in combat, where they can mean extra damage). Only sixes count; the other faces do nothing on their own.

This is a “count the successes” pool, not a total-the-dice system. A bigger pool simply means more chances to land a 6, so improving your attributes, skills and gear all translate directly into a fatter handful of dice.

Stress dice and Panic

The signature mechanic is Stress. As bad things happen — taking damage, running out of air, seeing something horrifying — your Stress Level climbs. On every roll you add a number of extra Stress dice equal to your current Stress Level, and those dice also score successes on a 6. So higher Stress makes you more likely to succeed — a jittery, adrenaline-fuelled edge.

The catch is the one. If any of your Stress dice roll a 1, you may be forced to make a Panic roll, and the higher your Stress the worse the panic result tends to be — from a nervous twitch all the way up to freezing, fleeing or firing wildly. Panic can cascade to nearby crewmates, turning one person’s breakdown into a group catastrophe. Stress therefore giveth and taketh away: it buys you extra successes at the constant risk of losing control at the worst possible moment.

How a roll resolves

To make a roll: build your base pool from attribute + skill, add your Stress dice, and roll them all together. Then read two things at once — how many sixes (your successes) and whether any Stress die shows a 1 (a potential Panic). If you fail, or want a better result, you may be able to push the roll: re-roll the dice that didn’t score, but at a price — pushing raises your Stress Level by one (and rolls the newly added Stress die too). A pushed roll is a genuine gamble: another shot at success, bought with more fear and a bigger Panic risk going forward.

Effective strategy

  • Manage your Stress like a resource. A little Stress helps — those extra dice win rolls — but every point compounds your Panic danger. Take chances to shed Stress (a moment of calm, safety, or the game’s recovery mechanics) when the pressure lets you.
  • Push with intent, not habit. Pushing is superb for a roll you truly need to make, but each push ratchets your Stress upward. Save it for pivotal moments rather than reflexively re-rolling every near miss.
  • Front-load the easy stuff. Do careful, non-urgent tasks while your Stress is low and there is no clock. You want your Stress dice to be few when precision matters and only high when desperation forces it.
  • Build the right pool. Since only attribute + skill (plus gear) sets your base dice, specialise. A crew that divides expertise — a pilot, a medic, a fixer — brings big pools to the tasks that count instead of everyone rolling thin.
  • Watch the whole crew’s Stress. Because Panic spreads, one overstressed teammate is everyone’s problem. Keep the group’s Stress in check, not just your own.

Beginner tips and common mistakes

  • Only sixes matter. Don’t total the dice — count the sixes. Everything else is noise except the ones on your Stress dice.
  • One success is often plenty. You don’t need a fistful of sixes for routine tasks; a single success carries you. Save the hope for extras where they actually improve the outcome.
  • Remember Stress dice cut both ways. New players chase the extra successes and forget the 1s. Every Stress die you roll is another chance to Panic — respect it.
  • Pushing isn’t free. The re-roll always costs Stress. Weigh whether the task is worth being one step closer to a breakdown.
  • Cinematic vs Campaign play differ. The game supports tense one-shot “Cinematic” scenarios and longer “Campaign” play, which pace Stress and recovery differently. Know which mode you are in so you spend and shed Stress accordingly.
