Voidtrain Achievements: Full List and Unlock Guide

Voidtrain features 55 total achievements across PC and console platforms, introduced primarily in Major Update 14204. These objectives track every phase of your journey through the Void, from early trolley construction and resource harvesting to advanced weapon assembly and Arena combat. Because the game allows continuous travel between depots without hard progression lockouts, achievement hunters can complete these objectives on a single save or set up specific runs for speed and danger milestones.

Voidtrain Achievements Overview

Official platform data from Steam and the Epic Games Store confirms 55 achievements worth 1,000 Gamerscore or XP. Twelve of these achievements were designed and contributed directly by community players, with their names officially credited in the unlock criteria.

Developer patch notes show several updates addressing achievement triggers:

• Patch 1.02 resolved platform tracking issues for Xbox and PC Game Pass players, specifically regarding the "Very Useful Engine" milestone.
• Patch 1.03 introduced a forced unlock check for players who met "Very Useful Engine" requirements earlier, and updated "It ain't much, but it's honest work" to trigger across all tiers of garden beds.
• Update 14363 addressed issues where the Flamethrower core failed to register for "A Kind of Magic" and corrected criteria checks for "Full Ahead!".

Combat and Arena Challenges

Several achievements test specific weapon manipulation and combat behavior against soldiers and Arena creatures:

1. Spray and Pray: Requires killing 3 enemies consecutively without reloading and without using an active weapon core. Community testing shows that high single-shot damage weapons, such as shotguns or high-tier rifles, prevent the need to cycle ammo between kills.
2. Shock Therapy: Demands hitting 4 or more enemies simultaneously with an annihilation sphere. This requires slotting the Annihilator core into your weapon, best executed against closely grouped swarm targets in the Arena.
3. Easy-peasy and On the brink: Completed by finishing all 5 waves of an Arena encounter. To earn "On the brink" simultaneously, you must keep your health from falling below 25% across the entire run. Preparing extra shield armor plates before triggering the Arena portal helps mitigate damage spikes.
4. BOOM!: Earned by eliminating a flying bomber-bug before it detonates. High-damage weapons are recommended to burst the target down immediately when it approaches during later Arena waves.
5. Mpemba Effect: Demands igniting and subsequently freezing the exact same target. This requires a weapon configured with elemental modules or using a combination of the Flamethrower core and an Ice Storm core/freezing attachment. Community guides note that performing this against high-health targets like the armored tank officer ensures the enemy survives the burn phase long enough to be frozen.
6. Demoted!: Requires finishing a tank officer via a melee strike while holding a weapon. Players reporting on Steam forums verified that you can reduce the officer's health bar using standard gunfire before dealing the fatal blow with a melee strike.

Train Expansion and Station Mechanics

Train customization and base building form a significant tier of milestones. You start with a bare trolley and gradually build up your rolling fortress:

• We need more platforms & An engineer, truly an engineer!: Building your initial railcar platform unlocks the first milestone. Achieving 12 wagon platforms requires progressing far enough to install a heavy locomotive engine, such as the Diesel Engine, to support the increased weight limit.
• Aquarius and Agricultural Milestones: Constructing 3 water condensers and placing 3 garden beds covers basic train survival needs. Per patch 1.03, garden beds of any tier count toward the "It ain't much, but it's honest work" requirement.
• Automation via Lootcatchers: Placing Lootcatcher nests lets your train passively pull resources out of the Void. Interacting with a nest to pull out any snagged item unlocks "Work up a sweat".
• Train Maintenance: Patch notes introduced train dirt mechanics caused by Void sharks, leeches, and character damage. Equipping the craftable mop grants "Train Flipper", while wiping away 5 mud patches unlocks "Squeaky Clean". Shooting a blue leech growth adhering to the locomotive grants "Don't stop me now".

Speed, Afterburner, and Void Traversal

Multiple achievements focus on continuous train speed between depots and minefield management:

1. Fury Road: Requires destroying 15 consecutive mines while running in afterburner mode. Community members troubleshooting this achievement noted that assigning Rofleemo companions to defensive turrets can cause the train to automatically drop down to medium speed when hazards appear. Unassigning companions from turrets allows you to maintain manual throttle on the afterburner while shooting incoming mines with primary weapons. Equipping prophecies that increase mine density can speed up this process.
2. Very Useful Engine and Full Ahead!: "Full Ahead!" checks that you drive from one depot to the next at any continuous speed without applying the brakes or stopping. "Very Useful Engine" requires maintaining medium speed or higher across the entire journey. Stashing sufficient coal chunks or fuel and repairing engine components beforehand ensures the firebox remains lit.
3. When this baby hits 88...: Demands running the train continuously in afterburner mode for at least 3 minutes. Carrying excess high-grade fuel or combining this sprint with an uninterrupted depot run allows the achievement to register cleanly.
4. Altered Void: Obtained by placing three prophecy tablets into the artifact pedestal located on the front nose of your train and starting the path through the depot exit gate.

Rare Weapon Assembly and Rofleemo Crew Tasks

Completing the final collection achievements involves managing weapon components, depot mini-games, and your Rofleemo companions:

• Our battle will be legendary!: Unlocked by equipping a single weapon with four legendary (yellow/orange tier) modules simultaneously. A complete assembly requires one legendary barrel, one frame, one magazine, and one grip. While high-level outposts and late-game loot chests drop legendary parts, players frequently use the depot slot machine to roll modules early by spending collected tokens.
• Rofleemo Milestones: Acquiring your first Rofleemo gives the (◕‿◕) achievement, while reaching the maximum crew of 5 unlocks "Dream team". Feeding any companion a mushroom provides "Is this edible!?".
• Musical Compositions: Reaching technology tier 8 unlocks crafting recipes for the Djembe, Kazoo, Domra, and Concertina at the workbench. Equipping and playing each instrument completes "One-Man Band". Playing an instrument at a depot near two companion Rofleemoes who join in with their miniature instruments unlocks "Rofl-band".
• Depot Interaction Milestones: At depot stops, scoring a soccer ball into the goal net awards "Voidcup", while spending 10 tokens in the slot machine unlocks "The game was rigged from the start". Combining multiple depot tasks—opening two containers, purchasing two vendor items, and spending two tokens in one visit—awards "Cleaned Out".
