Vehicle Classes and Statistics

Gaslands: Refuelled categorizes vehicles into distinct classes, each possessing unique statistics influencing their performance on the wasteland track. These classes – Scout, Fast, Standard, Heavy, and Tank – determine a vehicle’s Smash Attack dice pool, influencing collision outcomes. The rulebook, readily available as a PDF, details these classifications and their associated stats.

Key statistics include Handling, which affects maneuverability, and Armor, representing a vehicle’s resilience to damage. Vehicles gain additional characteristics through customization, detailed in the PDF rules, such as weapon systems and special gear. These modifications alter stats and introduce unique abilities. Players utilize form-fillable team sheets (often PDF downloads) to record these statistics, ensuring accurate gameplay. Understanding these classes and meticulously tracking stats, guided by the PDF resources, is vital for building a competitive and strategically diverse team capable of surviving the brutal arena.

Collision Resolution: A Detailed Breakdown

Gaslands: Refuelled’s collision system is a core mechanic, meticulously detailed within the downloadable PDF ruleset. Resolving impacts involves a multi-step process, beginning with determining vehicle orientation post-collision – crucial for subsequent actions. Players then declare reactions, choosing to brace for impact or attempt evasive maneuvers, impacting the outcome.

The heart of the system lies in the “Smash Attack” dice roll. The PDF clarifies that the number of dice rolled depends on the vehicle classes involved and any equipped gear. Results determine damage and potential effects, like spins or stalls. Quick reference sheets, often available as PDFs, streamline this process. Understanding the interplay between vehicle stats, reaction choices, and Smash Attack results, as outlined in the rulebook PDF, is essential for mastering vehicular combat and navigating the chaotic arena.

Determining Orientation After Impact

Gaslands: Refuelled’s PDF rules detail a straightforward, yet crucial, system for establishing vehicle orientation following a collision. After impact, a vehicle’s facing is determined by comparing the angle of the collision with its current direction of travel. The downloadable ruleset provides clear guidance on how to assess this angle, categorizing it into front, side, or rear impacts.

This orientation directly influences subsequent actions, such as shooting or ramming. The PDF emphasizes that a vehicle’s facing dictates its available actions and potential vulnerabilities. A side impact, for example, might limit maneuverability. Quick reference sheets, often found as companion PDFs, summarize these rules for rapid gameplay. Accurately determining orientation, as outlined in the core rulebook PDF, is vital for realistic and strategic vehicular combat within the wasteland.

Declaring Reactions During Collisions

Gaslands: Refuelled’s comprehensive PDF ruleset highlights the importance of declaring reactions immediately after a collision. Players must swiftly choose one of several possible reactions for their vehicle, influencing the outcome of the impact and subsequent gameplay. These reactions, detailed within the downloadable PDF, include bracing for impact, attempting to steer through the collision, or even initiating a counter-ram.

The chosen reaction can mitigate damage, alter the vehicle’s orientation, or even inflict additional harm upon the opponent. The PDF stresses that reactions are declared simultaneously, adding a layer of tactical unpredictability. Quick reference sheets, often available as supplementary PDFs, provide a concise reminder of available reactions. Mastering these reactions, as explained in the core rulebook PDF, is key to surviving the brutal vehicular combat of the Gaslands.

Smash Attack Dice: Vehicle Class & Gear Impact

Gaslands: Refuelled’s PDF rules detail how “Smash Attack Dice” determine the severity of damage inflicted during collisions. The number and type of dice rolled are directly linked to a vehicle’s class – from nimble bikes to hulking rigs – as outlined in the downloadable rulebook PDF. Heavier vehicles generally roll more dice, representing greater impact force.

Furthermore, equipped gear significantly modifies these rolls. Reinforced armor might allow re-rolls, while offensive weaponry could add bonus dice or change the dice type to inflict specific damage. The PDF provides detailed charts correlating vehicle class and gear with the appropriate dice pool. Understanding these modifiers, readily available in the comprehensive PDF, is crucial for maximizing offensive and defensive capabilities. Quick reference sheets, often found as companion PDFs, summarize these key smash attack rules for rapid gameplay.

Combat Rules: Shooting and Ramming

Gaslands: Refuelled’s PDF comprehensively covers both shooting and ramming, the core combat actions. Shooting mechanics, detailed within the downloadable rules, involve range determination, accuracy checks utilizing dice rolls, and applying damage based on weapon type. The PDF clarifies line-of-sight rules and the impact of environmental factors on shooting accuracy.

Ramming, equally crucial, is governed by speed and angle of impact. The PDF outlines how to calculate relative velocity and determine the collision angle, influencing the severity of the smash attack. Vehicle class and equipped gear, as detailed in the PDF, heavily modify ramming effectiveness. Successfully executing a ram requires strategic positioning and understanding the smash attack dice system. Quick reference sheets, often available as separate PDFs, condense these rules for faster in-game application, ensuring a dynamic and destructive vehicular combat experience.

Shooting Mechanics: Range and Accuracy

The Gaslands: Refuelled PDF meticulously details shooting, beginning with range determination – crucial for accuracy. Weapons possess varying ranges, impacting dice roll modifiers. Line of sight is paramount; obstructions detailed in the PDF necessitate clear targeting. Accuracy relies on dice rolls, modified by shooter skill, vehicle stability, and range.

The PDF clarifies how to apply these modifiers, ensuring fair resolution. Different weapon types inflict varying damage, also outlined within the rules. Environmental factors, like dust clouds or rain, can further reduce accuracy, adding realism. Quick reference sheets, often accompanying the core PDF, summarize these rules for rapid gameplay. Mastering shooting requires understanding these nuances, allowing players to strategically eliminate opponents in the post-apocalyptic arena. The downloadable PDF provides all necessary information for precise and engaging vehicular combat.

Ramming Rules: Speed and Angle

Gaslands: Refuelled’s PDF comprehensively covers ramming, a core combat tactic. Speed is critical; faster vehicles inflict greater impact, detailed in the rules. The PDF outlines how to calculate ramming speed based on movement allowances. Angle of impact significantly affects the outcome, influencing where damage is dealt. A head-on collision differs drastically from a glancing blow, with the PDF providing clear guidelines.

Ramming isn’t simply about speed; vehicle weight and armor play vital roles, modifying damage inflicted. The downloadable PDF includes charts for quick reference during gameplay. Successful ramming can disable opponents or force them into hazardous terrain. Players must balance aggressive ramming with the risk of self-damage. Mastering ramming requires understanding these factors, turning vehicles into devastating mobile weapons. The PDF ensures ramming is a strategic, impactful element of Gaslands: Refuelled combat.
