Outthink Raids, Optimize Your Colony & Conquer Chaos
Table of Contents
RimWorld's late game can throw massive raids, mechanoid swarms, and maddening events at you – but with the right strategies, your colony can thrive against all odds. In short: keep your colony lean and mean (control wealth!), design kill-zones that maximize damage, leverage DLC perks like mechanoid workers and psycasts, and prepare for the worst events with backup plans. Not enough time? Jump to the Quick-Start Tips for a rapid rundown. New to RimWorld? Start with our beginner's survival guide first. For everyone else, let's dive deep into advanced RimWorld mastery – from fine-tuning colony wealth to bending the game's hardest scenarios in your favor.

Quick-Start Tips (For the Impatient)
- Limit Your Wealth & Pawns: Fewer colonists + lower stockpiled wealth = smaller raids. Sell or destroy excess loot (don't hoard 200 weapons or 10 years of food). A small elite team with mechanoid helpers can out-perform a horde of colonists – and draws far fewer enemies.
- Killbox is King (But Make it Smart): Funnel enemies into a trap-filled corridor. Keep it short (so enemies can't pile in) and use close-range weapons (shotguns, SMGs) for highest DPS. Space turrets apart with walls to avoid chain explosions, and give your shooters solid cover (e.g. every other tile a wall) for 75% cover effectiveness. For detailed base design principles, check our comprehensive base building guide.
- Exploit DLC Abilities: Royalty permits = free reinforcement squads when overwhelmed. Ideology – pick memes that eliminate bad moods (e.g. Cannibal tribe never minds butchering). Biotech – draft a mechanitor with labor mechs (for work) and war mechs (for combat) that don't count as full colonists in raid calculations. Anomaly – capture monsters and turn them on your foes (yes, you can sick a reality-twisting horror on that siege!).
- Have a "Oh Crap" Plan: Always keep some emergency options handy. Examples: a packaged survival meals reserve + drop pods to evacuate if base lost; psychic shock lances to insta-down siege leaders or manhunters; an animal army or some crazed boomrats to release as distractions. On the hardest storyteller settings, one event can snowball – plan for failure as much as success.
- Optimize Everything: Set up efficient work schedules (give night owls night shifts, etc.), use zones to keep pawns from wandering into danger or wasting time. Place stockpiles strategically (raw materials next to crafting stations, dumping stockpiles in killbox for cover and slowing enemies). Utilize the new search (Z) to find items on a cluttered map. Every second saved is time to prepare for the next threat!
Overwhelming Raids: Outsmarting the Storyteller
Late game, many players feel the Storyteller (especially Cassandra or Randy on high difficulty) has it out for them – raids grow absurdly large and frequent. The key insight: raid strength scales with your wealth and population. Mastering RimWorld means learning to manipulate those variables in your favor.
Wealth Management 101: Less is More (Combat Power)
Every item in your colony – every golden statue, stockpiled parka, or pile of corn – contributes to your colony wealth, which in turn ramps up raid points. Advanced players deliberately limit wealth without crippling productivity. How? By following a Minimalist Colony philosophy:
Don't Hoard Unneeded Items
Sell, gift, or destroy excess. You do not need 500 leather armors from dead raiders or a barn full of random weapons. In fact, keeping them just invites larger raids for wealth you're not actually using to defend yourself. One player's guide puts it simply: "No hoarding of anything. Food included. You don't need 10 years worth of fine meals... nor hundreds of weapons dropped by raiders."
Don't Mine or Build Just for Show
It's tempting to mine every tile of plasteel or build a fancy throne room of solid gold. But unused resources sitting around are just raid bait. Leave metals in the ground until you actually need them; don't craft 20 swords hoping to sell later – that's wealth now. Each piece of art or high-value furniture, keep it if you truly need the mood boost; otherwise, skip or use cheap materials.
Spend Wealth on Consumables (or Investments)
Convert silver (wealth that attracts raids) into things that don't (or that actively help). For example, buy medicine, components, and advanced components in bulk – they will get used up (consumed) and save your colonists' lives, rather than sitting as wealth. Or invest in bionics/prosthetics for your pawns – yes they add wealth, but they directly increase pawn power, a worthwhile trade.
Population Control – Fewer Colonists, Stronger Colonists
The game also heavily factors your number of colonists into raid sizes. A crucial advanced strategy is to resist the RPG-style urge to "grow your colony endlessly." Instead, consider an intentional population cap. Many experts keep colony size around 6–8 in mid-game and maybe 12 in late-game, even rejecting recruits or not rescuing every stranger. Fewer pawns means fewer simultaneous threats to manage and smaller raids.
Advanced Tip: If you're truly finding raids "not fun" due to how scaling works, remember Custom Difficulty exists. RimWorld lets you adjust scaling factors like Threat Adaptation. Reducing Adaptation Growth or setting a max threat level can make raids plateau at a manageable size instead of an endless exponential curve.
Base Defense Mastery: Killboxes and Kill-Teams
When raiders or manhunter packs show up, a well-prepared base can make the difference between a fun firefight and total colony wipe. The go-to strategy for many advanced players is the Killbox – a carefully engineered deathtrap that channels enemies into a field of fire.
Building the Ultimate Killbox
A killbox is essentially a funnel + killzone. You use walls and doors to funnel enemies into a confined area where your firepower (turrets, traps, and colonists) is concentrated and ideally where enemies have no cover.

RimWorld killbox correct design with spaced turrets and cover (advanced defense). Note the short kill zone, staggered walls and barricades for optimal cover, and space between turrets.
How to Build a Simple Effective Killbox:
- Choose Location & Funnel: Pick a spot at your base perimeter where you will force all enemies to path. Build solid walls to guide raiders into a single-tile-wide entry corridor.
- Lay Traps in Entry: In the narrow corridor, install traps every other tile. Optionally alternate with low obstacles like fences: Trap, fence, trap, fence... so that an enemy stepping through hits a trap, then has to vault a fence (slowing them), then another trap.
- Design the Killzone Room: Just past the corridor, have it open into a wider room (e.g., 8 tiles wide and maybe 6–8 tiles deep). This room is where you'll place defenses.
- Place Turrets and Cover: Along the back of the killzone, position your gun turrets and firing line. Space turrets 2+ tiles apart (turret-wall-turret pattern works well). Intersperse chunks of wall and barricades for your colonist shooters.
- Lighting and Finishing Touches: Make sure the area is roof-free. Install a couple of standing lamps to keep it brightly lit at night. Clear any debris or plants from the floor. Consider putting an escape door at the back.
When Killboxes Aren't Enough – Flexible Defense
Killboxes are extremely effective for conventional raids, but RimWorld will throw situations they don't fully address: drop pod assaults right into your base, sappers who tunnel around your walls, or infestations that spawn inside a mountain.

Layered Defense Lines
Design your base with multiple perimeters. Maybe raiders breached the outer killbox? Fall back to the inner courtyard that's also set up with sandbags and cover. Think of medieval castles: outer walls and inner keep.
Mobile Response Team
Have a squad with good armor and weapons always ready to react to breaches or drop podders. For example, if drop pods bring pirates into your greenhouse, you might send 2-3 melee heavies to tie them up, while gunners reposition to cover.
Advanced Tip: In combat, focus fire on enemies one by one when possible. 10 enemies at half health shoot just as well as 10 healthy ones – better to drop a couple fully (removing their DPS from fight) than to half-damage many.
Special Challenges: Mechanoids, Infestations, and Disasters
RimWorld's AI storyteller has more than just human raiders up its sleeve. Let's tackle some of the most notorious challenges and how advanced players handle them.
Mechanoid Madness: Handling Mech Clusters and Centipede Swarms
Mechanoids are tough, often heavily armored, and feel "boss-like" compared to human raiders. By late game, you might face Mech Clusters landing on the map and big mech raids including multiple Centipedes, Lancers, Scythers, and the newer Biotech mechs.
EMP is Your Best Friend
Mechanoids are vulnerable to EMP stunning. An EMP grenade or mortar shell can put multiple mechs out of commission for a few seconds. Equip one colonist with an EMP launcher or grenades and have them take cover near the front – their sole job is to keep lobbing EMP every few seconds at the clustered mechs.
Focus Fire & Target Priority
Always prioritize the most dangerous mechs. Centipedes are the tanks – slow moving but soak damage and output nasty area attacks (Inferno cannon setting stuff on fire, or heavy blaster doing big area damage). A classic tactic is to have some colonists with high-DPS weapons concentrate on one centipede at a time.
Bug Infestations: Taming the Tunnels
If you have any underground or mountain base, infestations are a constant looming threat. Infestations spawn a cluster of mega-spiders, spelopedes, and megascarabs along with hive nodes, usually in areas with overhead mountain roof.

Burn Them Out (Heat Strategy)
Bugs are very susceptible to heat. If you can trap them in an area and crank the temperature beyond ~120°C, they will collapse or die quickly. Build heat traps: small rooms or corridors with doors that you can shut when bugs spawn there, and within those rooms have incendiary IEDs or chemfuel stockpiles.
Environmental Disasters: Toxic Fallout, Volcanic Winter, etc.
Some threats don't come in the shape of fangs or guns, but as Mother Nature (or space) taking a swing at you. Advanced colonies survive these by preparation and adaptability.
Toxic Fallout
A green haze covers the map. Any creature outside accumulates toxic buildup, which will eventually kill. The answer here is indoor living. Lock animals in a barn with stocked hay or kibble. Restrict colonists to an Inside zone: only under mountain or roofed areas.
Heat Wave
Temperatures soaring. If you're in a hot biome (desert, arid), you likely already have coolers. If not, build some quick. A trick: Passive coolers (from tribal tech) can still be built by advanced colonies if you have wood – they don't require power and lower a room by up to 15°C.

Mastering DLC Mechanics for a Strategic Edge
Each RimWorld expansion introduces new systems that, when mastered, dramatically improve your colony's resilience or capabilities. Advanced players weave these mechanics into their strategy from day one.
Ideology: Bend Morale to Your Will
Ideology lets you shape your colony's belief system. The advanced play here is to customize an ideology that minimizes your weaknesses and amplifies strengths. This often means eliminating mood penalties that would otherwise plague an extreme strategy.

For example, running a "cannibal" or "dark" colony can be incredibly powerful – no mental breaks from butchering raiders, and free meat supply. But normally that's unthinkable due to mood debuffs. With Ideology, you can create a culture where butchering humans is acceptable or even loved.
Royalty: Psycasts and Noble Perks in Advanced Play
The Royalty expansion might seem like it introduces prissy nobles who demand fancy bedrooms – a liability. But in the hands of an advanced player, a well-managed noble or two is like having a trump card for tough situations.
Psycast Power
High-level psycasters can literally turn battles around. Abilities like Skip (teleport someone a short distance) can yank an enemy out of cover into your killbox, or skip away a grenade thrown at you. Invisibility can allow daring maneuvers like rescuing a downed ally under enemy noses.
Biotech: Mechanoids and Genetics – Designing Your Colony's Future
Biotech is almost a game-changer expansion: mechanitors (controlling mechanoids), gene-modding and child-rearing. In advanced play, Biotech provides arguably the biggest power boosts – if used right.

Labor Mechs
These include Haulers, Cleaners, Constructoids, Agrihand (farmer mech), etc. They handle the grunt work tirelessly. Key advanced tip: dedicate one mechanitor solely to running a fleet of labor mechs, and keep them near base to supervise.
Genetic Super Soldiers
In advanced play, you can create colonists that are just flat-out better. For combat, you might give a pawn Strong Melee Damage, Tough skin, Fire resistant, Aggressive (for melee hit chance), etc., turning them into an absolute unit in melee who can solo three raiders at once.
Anomaly: Horror Unleashed, and Harnessed
The Anomaly expansion is the newest (horror-themed) and it spices up endgame with bizarre events that defy typical strategies. But advanced players can not only survive anomalies – they can exploit them.
Anomaly Events Overview
These range from: an invisible night predator that steals souls (Revenant type creature), a giant Flesh Mass spreading over the map, a Parasite infiltration where one of your colonists is secretly infected, a crashed Obelisk doing weird things like mutating or copying pawns, and colonists obsessing over a golden cube artifact.
Advanced Tip: Once you survive a couple of anomalies, you might start almost hoping for an anomaly event because it can break the monotony of raid-kill-raid, and give you unique rewards to boost your colony further.
Putting It All Together: The Endgame Arsenal
An expansive RimWorld colony after 50 years, valued at 13.6 million wealth - a testament to successful long-term strategy and wealth management.
At this stage, we've covered specifics – wealth control, killboxes, DLC tricks, special events. The true "advanced strategy" is integrating all these into a coherent playstyle that prevents failure modes. Think of each tactic as a layer of safety:
- You limit wealth and pop to reduce raid threat (Layer 1).
- You build strong static defenses (killbox) to handle the majority of threats (Layer 2).
- You have mobile backup and special tactics for edge cases (Layer 3).
- You exploit game systems (DLC powers, anomalies) to further tilt odds in your favor (Layer 4).
- You have redundancy and plans for disasters (Layer 5).
One might ask: does this make the game too easy? Well, on 500% "Losing is Fun" with Randy or Cassandra and using no-pausing, even these advanced strategies won't make it "easy" – but they make it possible. And that's the thrill for an advanced player: turning a story that was supposed to break you into one where you break the story.
Action Steps Recap
Manage wealth, fortify smart, leverage every tool (from war mechs to psycasts to proximity alarms), and always have a Plan B (or C) because RimWorld will test every weakness – you now have the knowledge to ensure your colony has none.

Remember RimWorld's Golden Rule
"Losing is fun."
With these strategies, you'll do a lot less losing – but when you do, take it in stride, learn from it, and start that next colony even stronger. The true mastery of RimWorld comes not just from surviving, but from creating stories worth telling.
