Core MechanicFor skill checks, roll a d20 and add the two relevant Talents plus the applicable Education score. A total of 21 or higher succeeds. Before a non-damage d20 roll, Luck Points can add +1 each to its bonus.Roll 2d20 against the sum of an attribute and a skill. Each die at or below that total scores a success. A roll of 1 scores two successes, and tagged skills extend this critical range to the skill rank. Meet the difficulty with your total successes. Extra successes become shared Action Points that can buy more dice or information. A roll of 20 creates a complication even when the test succeeds.

Best ForGroups who want a survival-focused science-fiction campaign where characters cross frozen ruins, manage limited equipment, and resolve fights on a tactical grid.Groups who want Fallout campaigns built around wasteland quests, scavenging, and customizable survivors. Groups who enjoy tactical firefights and turning recovered junk into equipment upgrades.
HighlightsFrost Points turn prolonged exposure to subzero conditions into resilience checks, so shelter and protective gear shape expeditions. The optional Tuning Session assigns Talent scores through a short character-memory scenario, tying early choices to the resulting build. Combat uses a 2-meter grid with optional Perks that award attack bonuses for flanking or high ground.Shared Action Points let the group turn strong rolls into support for later tests. Perks and equipment modifications let survivors develop distinct specialties without classes. Scavenging tables connect dangerous locations to supplies and crafting materials.
ConsiderationsExposure to subzero temperatures triggers a Resilience check every 20 minutes of real table time and failure costs one Frost Point. Broad equipment archetypes rely on the Dungeonteller to define the specific items characters encounter. Combat resolves each attack through opposed rolls before damage is rolled.Attacks can trigger several damage effects alongside armor checks for the struck body part. Ammunition and carried weight require ongoing bookkeeping. The core setting concentrates on the Commonwealth from Fallout 4.
