Going Medieval

Infamy is a hidden settlement stat that climbs as you do genuinely bad things; the confirmed driver is killing innocent (non-hostile) NPCs. Push it to 100% and this unlocks - which is also the gate that lets you accept the Tyrant Overlord objective for No Rest for the Wicked. Best done deliberately on a "dark" save you don't mind burning. Pairs with Memento Mori.

Unlock 10 research items. Steady research over a settlement clears this; Luminary Researcher (25) is the real grind.

Survive a full year (48 days). The natural reward for keeping one settlement going; the seasonal cheevos (Heating Up, Winter Is Coming, Winter Is Here) come on the way.

Survive your first raid. Raids come automatically as your settlement grows - have a few armed settlers and some walls and you'll be fine. Killing an attacker also gets you Retribution.

Gather 10 settlers in one settlement - recruit your way up to a population of 10 (immigrants, recruited prisoners via Bury the Hatchet, etc.).

Build a wooden beam - place a beam, the support piece you use when roofing larger spans and floors above ground. You'll do it early without thinking about it.

Send out 10 caravans in total - the single version is Go Forth. Regular trade runs get you here without effort.

Needs an Unforgettable-quality Ritual - the Oak Brethren event. Hold it at a Ritual Circle in an impressive Oak Brethren temple (Temple of Timber) with a high-skill Druid. Same quality recipe as Feast Mode.

Hunt 20 boar in total - the 5-kill version is In Hog Heaven. Range them down; don't melee a boar you've only winged.

One of three "kill an enemy with a mechanism" cheevos (see Gate Expectations and Heavy Artillery). Build a drawbridge over a deep pit on a path raiders use, wait until an enemy is standing on it during a raid, then toggle it to drop them. Easiest set up right by your gate so attackers have to cross.

Recruit a prisoner into your settlement: hold them in a prison cell and assign a settler to win them over (it whittles down their resistance over time). See Conversion for 5.

Catch 5 fish - designate a fishing zone on water and assign a fisher. Builds toward Reel Skills (20) and Fifty Shades of Bait (50).

Recruit 5 prisoners in total - the single version is Bury the Hatchet. A steady supply of downed raiders plus a dedicated recruiter makes this passive.

Hunt 20 deer in total. Just keep a hunter on deer through the game; you'll likely pass this without trying. The 5-kill version is Oh Deer!.

Defeat a bandit camp - these appear on the region map; send an armed party to clear one out. (Clearing three strongholds is the bigger The Art of War objective.)

Dismantle 5 items - select a built item and order it deconstructed to reclaim materials. See Nothing Wasted for 50.

Hunt 5 wolves. They're predators and will fight back - bring more than one hunter, or thin them with a trapped chokepoint. See Where Wolf? for 20.

Hunt 5 mallards. Mallards are waterfowl - you need a map with water/wetland for them to appear. See Quacktical Strike for 20.

Needs an Unforgettable-quality Study Group. Run it in an impressive library with a high-skill Librarian. Same quality recipe as Feast Mode - the better the room and the role-holder, the higher the tier.

Level up your settlers 100 times in total - cumulative skill-ups across the colony. It just accrues as people work; you'll pass it on a long save.

"Unforgettable" is the top quality tier for an event, scored on points. Stack everything: an impressive dedicated dining hall (high room wealth + beauty + some open floor), a high-skill cook and a bard, and plenty of good-quality food and drink. Over-invest in the room and the people running it and the feast tips into Unforgettable. The exact threshold isn't published, so go overboard. Same recipe drives Praise Be, Eureka!, Know Thy Enemy and Blessed Be.

Store 10,000 nutrition at once - keep stockpiling preserved food (a cellar/larder slows spoilage). Next: Fit For A King (20,000).

Tame a pheasant. Low-HP and predator-prey, so clear foxes/polecats first (see Fowl Play).

Catch 50 fish in total - cumulative. A standing fishing zone clears it over time. Smaller versions: Casting Call, Reel Skills.

Explore a loot stash - send settlers to investigate a stash/point of interest that appears on the region map and clear it for the loot.

Craft 5 works of art - have a settler produce art (sculptures and the like) at the right station. Art also raises room impressiveness, which helps your Unforgettable events.

Store 20,000 nutrition at once - the big larder cheevo. Preserve food in a cool cellar so it doesn't rot, and bank a big surplus. Smaller versions: Putting Food on the Table, Feast or Famine.

Hunt 5 hares - and this is one of the most-missed cheevos in the game. Hares only spawn on Valley/Hills/Mountain maps (not Marsh), and at 15 HP foxes and polecats instakill them the moment they appear, so people go 100+ hours never seeing one. Start on a Valley/Hills map and cull your predators early so hares survive long enough to shoot. Same fix for Wabbit Season and the tame Good Hare Day.

Tame a deer. Deer are plentiful, so an easy one.

Craft 10 weapons - queue weapons at a smithy/workshop. Arming your settlers for raids gets you most of the way.

Hunt 5 pheasants. Like hares they're low-HP (10) and get instakilled by foxes and polecats on spawn, so cull predators first. See Most Unpheasant for 20.

Have 5 settlers each assigned a role in one settlement - assign distinct roles (cook, broker, chaplain, etc.) to five colonists. Those roles also gate the Unforgettable events like Feast Mode.

Crush a raider with a portcullis: build one in a gateway the enemy funnels through, then drop it while an attacker is underneath. One of the trap trio with Bridge Too Far and Heavy Artillery.

Build an enclosed room: surround a space with walls, add a door, put a roof over it and a floor down. Most of the "construct an X" cheevos (Hammer Time, Kitchen Impossible, What's Up, Doc?, Shhh..., The Greatest) are just enclosed rooms with the right furniture inside.

Send a caravan out to the region map - pick settlers, load goods, and dispatch them to a destination. See Beyond Our Borders for 10.

Tame a hare - subject to the same hare problem as Food Chain: they only spawn on Valley/Hills/Mountain maps and get eaten by foxes/polecats on sight, so cull predators first and keep your tamed hare protected.

Harvest 200 crops in total - cumulative across the game, so a steady farm gets you there. The smaller versions are Having A Field Day and Reap What You Sow.

Construct a Workshop - enclose a room containing a crafting workstation. Research the relevant station first if it's locked.

Harvest 5 crops - sow a small field and bring in the first harvest. Builds toward Reap What You Sow (50) and Green Thumb (200).

Survive until the first summer. A season is 12 days; this comes on its own as the seasons roll round, alongside Winter Is Coming, Winter Is Here and All Year Round.

Kill an enemy with a trebuchet. Build and crew one, then bombard a raid stack with it during a siege. One of the trap trio with Bridge Too Far and Gate Expectations.

Hunt 5 water voles. They live at the water's edge, so you need water/wetland on the map. See Varmint Violence for 20.

Cook a meal at a campfire - build a campfire and queue a meal on it. Your earliest cooking, before you have a proper kitchen (Kitchen Impossible).

Enclose a room and furnish it as a Church of Restitution chapel: a Restitutionist Shrine plus a Restitutionist Lectern, with no opposing (Oak Brethren) shrine or workstation in the room. Both faiths can coexist in your settlement, so you can build this and Temple of Timber in the same game.

Hunt 5 boar. Assign a hunter with a bow; boar hit back, so shoot from range. See Boar and Peace for 20.

Take 5 prisoners in total - down-and-capture raiders rather than killing them. The single version is Throw Away the Key; recruiting them gets you Bury the Hatchet and Conversion.

Construct a Kitchen - an enclosed room with a cooking station (a stove/hearth) so it qualifies as a kitchen.

Needs an Unforgettable-quality Martial Training event, run by a high-skill Sergeant-at-arms in a good training space. Same quality recipe as Feast Mode.

Tame a mallard. Needs water terrain on the map for one to be around.

Unlock 25 research items - the research cap-stone. Keep a dedicated researcher (or two) studying all game; you'll need most of the tree.

Tame a wolf. Have a settler tame it - the better their taming skill the higher the chance, so level it on easy animals first (The Rat Pack, Tiny Treaty). Wolves can turn, so keep it fed and handled.

A Grand Objective (1.0 endgame). These are mutually exclusive - once you accept one you are locked out of the other five, so save first and expect to finish this on its own settlement (see Mind Over Matter, Natural Order, Redemption, The Art of War, No Rest for the Wicked).

Charter Fair is the trade path: build out your merchant economy (merchant stalls, a market cross, a treasury), level a Broker and barter hard to raise your trading standing. Once it is high enough a broker offers a major trade deal - accept it and send caravans to the marked region-map location. It concludes with a group of merchants arriving at your settlement.

Get a humanoid corpse (a dead raider does nicely), then butcher it into a trophy: place a Butchering Table, edit its bill to produce a Trophy from the humanoid corpse, and put up an empty Trophy Rack on a wall for it to display on. Grim and quick.

A Grand Objective (1.0 endgame) - mutually exclusive with the other five, so save before accepting.

New University is the scholarly path: raise your intellectual standing by levelling a Librarian and running study groups, get a Grand Research Desk into a proper Fellows' Library, and have your scholars write Influential Treatises. Complete the chain to convert the settlement into a university.

Hunt 20 pheasants in total - the 5-kill version is Fowl Play. Predators eat them fast, so keep foxes and polecats down.

A Grand Objective (1.0 endgame) - mutually exclusive, so save first. This is the Oak Brethren (pagan) path; pursuing it pushes Church-of-Restitution settlers to leave.

Raise your Oak Brethren standing with a Druid and rituals. A pilgrim event reveals a dying mighty oak - retrieve the sapling, plant it in an Oak Brethren Sanctuary, and draw 5 pagan pilgrim witnesses to consecrate it.

Hidden, and the villain ending. A Grand Objective (1.0 endgame) - mutually exclusive with the other five, so do it on its own save.

You first have to reach 100% Infamy for Absolute Villainy - that is what unlocks the Tyrant Overlord objective to accept. Completing the objective is what earns this. The exact steps aren't documented publicly yet (the devs only say "survive the consequences of your actions"), so follow the in-game objective log; I'll fill in the specifics once they're confirmed rather than guess.

Dismantle 50 items in total - the single big version of Disassembled. Tearing down and rebuilding as your settlement grows clears it naturally.

Fend off an ambush - beat back an ambush event. Keep your settlers grouped and armed when you're out on the map or expanding.

Unlock your first research item. Research comes from studying books at a desk - put a settler on it and you'll have this in minutes. The rungs above are Onward (3), Studious Researcher (5), Adept Researcher (10) and Luminary Researcher (25).

Cumulative - hunt 5 deer over your playthrough. Assign a hunter with a bow. See Deerly Departed for 20.

Unlock 3 research items. Keep a settler studying. Next rungs: Studious Researcher (5), Adept Researcher (10), Luminary Researcher (25).

Tame a fox. Same drill as any tame - assign a handler and let skill do the work.

Hunt 5 foxes. Worth doing early anyway - foxes are the main thing eating your hares and pheasants. See Zero Fox Given for 20.

Needs an Unforgettable-quality Eucharist. Hold it in a richly-furnished Church of Restitution chapel (House of the Holy) with a high-skill Chaplain running it, and lay on bread and wine to raise the quality. Same quality recipe as Feast Mode - over-invest in the room and the chaplain.

Store 5,000 nutrition. This is your stored food total, so build out larders and keep a food surplus rather than eating it all. Builds toward Feast or Famine (10,000) and Fit For A King (20,000).

Hunt 20 mallards in total - the 5-kill version is Duck, Duck, Juice. Needs water terrain on the map; dry maps won't have them.

Hunt 20 rats in total - the 5-kill version is Squeak & Destroy.

Harvest 50 crops in total. A working farm clears this in a season or two. Next: Green Thumb (200).

A Grand Objective (1.0 endgame) - mutually exclusive, so save first. This is the Church of Restitution path; pursuing it pushes opposed settlers to leave (the mirror of Natural Order).

Raise your Restitution standing with a Chaplain and sermons, build a Reliquary Chapel, retrieve a holy relic from the region map, and draw 5 pilgrim witnesses to make your settlement a centre of pilgrimage.

Catch 20 fish in total. Keep a fisher on a water zone. Next: Fifty Shades of Bait (50).

Kill a raider. You'll get this in your first proper fight; arm a couple of settlers. Fending off the attack also ticks ...And Don't Come Back!.

Construct a Library - an enclosed room with a research desk and bookshelves. Doubles as your research room for Novice Researcher onward.

Hunt 5 rats. They're common vermin; a hunter clears them easily. See Rat-astrophe for 20.

Unlock 5 research items - keep researchers studying. Builds toward Adept Researcher (10) and Luminary Researcher (25).

Tame a boar.

Enclose a room and furnish it as an Oak Brethren temple: an Oak Brethren Shrine plus a Ritual Circle, with no opposing (Restitutionist) shrine or workstation. Not mutually exclusive with House of the Holy - keep the two faiths' shrines in separate rooms so worshippers don't take a mood hit.

A Grand Objective (1.0 endgame) - mutually exclusive, so save first. The martial path.

Raise your military standing by winning battles, then defeat the three bandit strongholds that appear on the region map to earn the title of Protector of the Realm.

Survive your first day. Unmissable - it ticks the moment day one ends.

Survive 7 days. Just keep everyone fed and warm through the first week.

Construct a Great Hall - a large, suitably grand enclosed room. An impressive one also helps your Feast Mode feast hit the Unforgettable tier.

Tame a rat. Common and easy - a good one to level your taming skill on.

Down a raider in combat (don't kill them), then capture the unconscious body. Build a room with a prison bed so you have somewhere to hold them. See Jailhouse Rock for 5.

Tame a polecat. Polecats are nocturnal, so you'll only find them prowling at night - easy to miss if you're not watching after dark.

Hunt 20 water voles in total - the 5-kill version is Holey Voleys. Needs water terrain.

Defeat an enemy settlement - take the fight to the region map and wipe out a hostile settlement with a war party.

Tame a water vole. Found at the water's edge, so needs water/wetland on the map.

Hunt 20 hares - see Food Chain for the full warning. Short version: Valley/Hills/Mountain map, kill off foxes and polecats early or the hares get eaten before you can.

Construct a Medical Room - an enclosed room with a bed designated for treatment so it counts as a medical/hospital room.

Hunt 20 wolves in total. Culling wolves early also protects your prey animals, so this overlaps nicely with the hare/pheasant hunts. The 5-kill version is Don't Cry Wolf.

Survive until the first autumn - just keep the colony alive as the seasons turn.

Survive until the first winter. Stockpile food and fuel and wall in your settlers before it bites.

Hunt 20 foxes in total - the 5-kill version is Outfoxed. Clearing foxes protects Food Chain's hares and Fowl Play's pheasants, so do it as pest control.
