Unlocking all achievements in RimWorld requires completing a mix of vanilla survival milestones, complex DLC-specific quests like the Archonexus victory, and long-term colony management feats. Because Ludeon Studios integrated Steam achievements natively into the base game alongside the RimWorld Steam Page updates, players must juggle vanilla mechanics from the Official Ludeon Studios Website alongside expansions like Royalty, Ideology, Biotech, and Anomaly. This comprehensive guide details every step, strategy, and setting optimization needed to achieve 100% completion without relying on cheap mods or external achievement unlockers, though tracking progress via the RimWorld Official Wiki is heavily recommended.
Understanding RimWorld Achievement Design
Unlike action titles where achievements test purely mechanical reflexes, RimWorld achievements test your understanding of systemic survival, storyteller mechanics, and long-term resource economy. To make this grind efficient, it is best to play on custom difficulty settings where you can tweak parameters like threat scale, instant death chances, and incoming colonist recruitment rates. However, ensure that you do not enable developer mode permanently if you want your runs to feel authentic, though turning it on briefly to test pathfinding bugs is common practice among veteran achievement hunters. For players transitioning from other complex titles, checking out our guide on how to unlock all achievements in Nine Sols can provide a great frame of reference for methodical completionist runs.
Storyteller and Difficulty Settings for Achievement Hunting
Your choice of storyteller—Cassandra Classic, Phoebe Chillout, or Randy Random—dictates how predictable your challenges will be. For survival milestones, Phoebe Chillout on 'Strive to Survive' or 'Rough' difficulty offers predictable lulls between major raids, giving your builders and crafters ample time to grind out specific items. If you need to boost your system performance while handling massive late-game colonies with hundreds of pawns and animals, consider optimizing your hardware setup by following our Monster Hunter Wilds PC settings guide or learning from the optimization tips in Lenovo Legion Go best graphics settings to minimize stutter during massive mechanoid raids.
Conquering Vanilla Victory Conditions
The core achievements in RimWorld revolve around escaping the planet via the traditional methods outlined in the base game code. The most straightforward path is constructing your own spaceship from scratch. You will need to research Ship spaceflight, Ship computer core, Ship reactor, and Ship structural beam. Building the reactor requires significant quantities of plasteel, uranium, and advanced components, meaning your mid-game economy must prioritize deep drill mining and long-range mineral scanner caravans.
The AIA and AI-Driven Ship Launch Strategy
Once the ship reactor is powered on, it triggers a mandatory 15-day countdown where every hostile faction on the planet launches continuous waves of raids against your base. To secure this achievement safely, your colony must be surrounded by three layers of granite or plasteel deadfall traps, uranium slug turrets, and heavily armored melee pawns blocking chokepoints. Alternatively, you can pursue the AI persona ship journey across the planet to an existing landed ship, which eliminates the need to build every ship component yourself but forces you to caravan across dangerous biomes.
Mastering the Archonexus Questline Achievements
Introduced in the Ideology expansion, the Archonexus victory is perhaps the most time-consuming achievement chain in the entire game. The process requires you to sell your thriving, wealth-maximized colony three successive times to a peaceful AI tribe in exchange for a piece of a map leading to the mythical Archonexus. Each reset strips you down to just five colonists and a tiny amount of silver, forcing you to rebuild your civilization from scratch while facing scaling late-game raid difficulties.
First and Second Colony Resets
For the first reset, you need a colony value of at least 350,000 wealth. Before accepting the trade, stockpile portable wealth such as gold, hyperweave, and masterwork weapons in your colonists' inventory or cryptosleep cogs so your starting five pawns aren't entirely destitute in the new tile. Ensure your chosen starting pawns for the reset have high Crafting, Intellectual, and Construction skills to fast-track research benches and secure early perimeter defenses against tribal ambushes.
Unlocking Expansion-Specific Feats
With multiple expansions installed, your achievement pool expands to cover psionics, mechanoid gestation, ideological rituals, and eldritch horrors from the Anomaly DLC. For Royalty achievements, you must guide a colonist to the highest Imperial title of Count or Countess by completing royal quests, hosting elaborate speeches, and appeasing the Stellarch. This requires maintaining a throne room adorned with fine flooring, gold columns, and grand sculptures to satisfy title room requirement scores.
Biotech and Anomaly Milestones
The Biotech expansion introduces achievements tied to gene-modding, mechanoid overseers, and raising children from infants to capable workers. To unlock high-tier mechanoid achievements, your mechanitor must defeat the three high mech bosses—the Apocryphon-adjacent Diabolus, the heavy-artillery War Queen, and the bullet-hell Apocriton.

Surviving Extreme Biomes and Iron-Man Runs
Several achievements test your mastery over environmental hazards, requiring survival in extreme biomes like the Sea Ice or Extreme Desert without relying on standard farming or temperature controls. In Sea Ice, your primary strategy relies on cannibalism, butchering dropped raiders, setting up indoor hydroponics basins running on wood-fired generators, and utilizing insulated double-walled steel structures.
Perma-Death and Commitment Mode Tactics
Playing on Commitment Mode—RimWorld's version of iron-man mode where manual saves are disabled—is mandatory for certain elite achievements. To protect your colony from unfair wipes due to random drop-pod raids crashing directly into your hospital, maintain backup defense lines, keep key pawns in armor even when idle, and never hesitate to draft non-violent pawns to carry injured fighters away from incendiary shell fire.
Advanced Colony Wealth Management and Endgame Cleanup
As your colony grows into a multi-generational powerhouse, managing your total wealth is critical to preventing unmanageable raid sizes from overwhelming your defenses. Store surplus silver and high-value loot inside sealed stone chambers or load them into pack animals and send them on permanent trading caravans across the world map. This keeps your base wealth artificially deflated while your pawns train their shooting and melee skills against manageable threats.
Finalizing the 100% Completion Grind
Once you have conquered the major victory conditions, clean up remaining miscellaneous achievements such as taming a thrumbo, curing chronic illnesses with glitterworld medicine, executing a successful prison break suppression, or converting a pawn to a radically different ideology through constant interaction. By methodically ticking off these boxes across multiple themed playthroughs, you will secure every single Steam achievement that RimWorld has to offer, cementing your status as an elite planetary survivor.
