The Year Zero System Perfected#

The Alien RPG runs on Free League’s Year Zero system, refined to its apex predator form. Players roll pools of six-sided dice, looking for sixes to succeed. Your dice pool combines attribute (Strength, Agility, Wits, or Empathy) plus skill ratings, typically ranging from 5-8 dice for competent characters.

What sets this implementation apart is the push mechanic. Failed a critical roll? Push it by rerolling any non-sixes, but gain stress in return. This simple choice creates agonizing decisions - do you risk accumulating stress for another shot at success, knowing that stress itself becomes increasingly dangerous?

Stress: The Heart of Horror#

The stress and panic system transforms the Alien RPG from a simple dice game into a psychological thriller. As characters accumulate stress through pushing rolls, witnessing horrors, or encountering xenomorphs, they add yellow stress dice to every roll.

As you gain stress, you’re actually increasing your chances of success. But whenever that panic starts to hit, the game almost writes itself

These stress dice create a double-edged sword: rolling sixes on them counts as successes, making stressed characters perform better under pressure. However, rolling a one on any stress die triggers immediate failure and forces a panic roll, potentially causing your character to freeze, flee, or worse.

Essential Products to Get Started#

The Alien Starter Set provides everything needed for immediate play:

• Basic rules covering all core mechanics
• Custom dice featuring facehugger symbols for ones on stress dice
• Pre-generated characters with personal agenda cards
• Ship maps and punch-out tokens
• The acclaimed adventure “Chariot of the Gods”

For deeper exploration, the full Alien RPG Core Rulebook expands with complete lore, extended rules, ship combat, and “Hope’s Last Day” - a prelude adventure to the events of Aliens.

Character Classes and Personal Agendas#

Nine distinct classes capture every archetype from the franchise: Colonial Marines, Company Agents, Scientists, Pilots, Roughnecks, Officers, Medics, Marshals, and even Kids. Each class specializes in different attributes and skills, with unique talents like Marines pushing strength rolls multiple times or Pilots excelling at emergency maneuvers.

Personal agendas add another layer of tension. These secret motivations - ranging from “just get paid” to “preserve the specimen for the Company” - create natural conflicts without forcing antagonism. When one character wants to save everyone while another prioritizes escape, dramatic moments emerge organically.

Combat: Fast, Brutal, Unforgiving#

Combat uses abstract positioning with fast and slow actions per turn. Characters might have 2-5 health points, while xenomorph attacks deal devastating damage. The drone xenomorph’s attack table ranges from stress-inducing stalking to instant-kill headbites on a roll of 6.

If the first time a Xenomorph attacks a player and I roll a six… we’re not even halfway into my night of gaming

Most xenomorphs have armor requiring sixes to negate damage, acid blood that sprays when killed, and multiple initiative cards letting them act more frequently than players. Smart groups quickly learn that running often beats fighting.

Cinematic vs Campaign Play#

The system excels at cinematic one-shots mimicking the films’ structure. Stress naturally builds toward explosive conclusions where discovering who survives becomes the primary goal. Campaign mode offers slightly more forgiving stress recovery, though the universe remains decidedly hostile.

Key Takeaways#

• The Year Zero dice pool system creates elegant, fast-paced gameplay perfect for horror
• Stress mechanics brilliantly simulate mounting psychological pressure
• Personal agendas generate organic character conflict without forced PvP
• Combat remains lethal enough that escape often trumps confrontation
• The starter set ranks among the best introductory products in tabletop gaming
• Free League’s upcoming Alien RPG Evolved promises refinements based on five years of player feedback

System Strengths and Considerations#

The Alien RPG shines when recreating the original film’s cat-and-mouse terror. Single xenomorphs against small crews create perfect tension. However, recreating the action-heavy sequences from Aliens proves challenging - the Colonial Marines’ last stand would likely result in total party kills under these rules.

Game masters should consider adjusting xenomorph attack tables early in sessions, potentially saving instant-kill results for climactic moments. The system also adapts excellently to other horror settings: zombie apocalypses, slasher films, or cosmic horror all translate seamlessly to these mechanics.

Conclusion#

The Alien RPG stands as one of the finest horror RPGs available, marrying cinematic storytelling with mechanics that reinforce themes of desperation and survival. Whether you’re a franchise fan or simply seeking intense one-shot experiences, this system delivers unforgettable sessions where no one can hear you scream.

The combination of accessible rules, escalating tension through stress, and faithful adaptation of the source material creates something special. Free League has crafted not just a licensed game, but a definitive expression of survival horror at the gaming table.
