How to unlock all secret technologies.

This guide will show you how to unlock all of the game's secret technologies!

This guide doesn't cover technologies that have an easy-to-understand unlock requirement such as "Win with a specific Thinker".

Highlighted is the more important stuff.

Highlighted and Underlined = TLDR.

1. Lamba House

Solution confirmed by greensniperhat

Unlock requirement: Unlocked by building a lot of homes on top of elevations.

Build elevations off the edges of cliffs and then put homes on top, I'm fairly sure Sumac's passive doesn't count.

2. Ringhouse

Build a lot of homes (exact number unknown) around and within your hearths own radius. So only withing your starting area.

3. Mushroom Hut

Produce a lot of mushrooms, I recommend placing down 15-20 mushroom logs and letting your braves farm for a while.

4. Gosanke Harborhouse

Alright, through trial and error I've finally managed to get it but... Man, did it take time.

Anyways, here's how you get it: Go to the Pebbles biome and Kill (or befriend?) the nomads residing on the Gosanke Harborhouse. Finally have your thinker of choice walk up to their campfire on the Gosanke Harborhouse. Congratulations, you got it!

Easiest solution: Choose Achiote, build a small army, take his scaffolding festival along with a bridge movement tech and build a bridge right over to the Gosanke Harborhouse. Now all you need to do is kill the nomads and take your thinker to their campfire.

If: you go for normal Achiote then movement technologies such as: Boat(s), Bridge or Mud Arches will be easier to build with his normal scaffolding.

If: you take Achiote's B-side then movement technologies such as: Stilt Pads, Stilt Elevations and Pillar Paths will be easier to get with his B-side scaffolding.

If you have him unlocked I recommend going with his B-side as you can place down as many stilt pads, stilt elevations or pillar paths as you need and have them all instantly built with only 1 B-side scaffolding.

Hope this helps! :)

5. Featherwing Coop

KaingaDev confirmed you can unlock the Featherwing Coop with the Windcatcher

Unlock requirement: Spawn with Frilled Houses or Windcatcher and have wind blow into them.

Easiest solution: I recommend starting in The Flatlands biome and building a very wide city so there's a greater chance of the wind bumping into one of the Frilled Houses.

6. Firetower Hearth

Solution provided by Faxu

Challenge requirement: Win a game by not placing down any banners and only picking up 2 tech.

Easiest solution: Pick Achiote for fast building speeds and go to The Flatlands biome with the Sky Lines festival selected. The sky lines festival doesn't have any banner requirement and if you run out of mud you can always just force your braves to collect resources outside the hearths radius.

@montinje It might work, you can always return here with your findings should you discover a new solution like that. Though I would recommend just killing them and building lots of stilts since balloons can be a bit unreliable in where you land after you exit them. They also cost fabric which can be a bit hard to come by.

[montinje]

I wonder with the harbour house can you stealth it with balloons and a tough to kill or sneaky thinker without needing to kill the nomads?

[greensniperhat]

Can confirm for Lambda: get stilts, and build a lot of houses entirely on them.

This is great!
Glad to see these kinds of guides :) By the way, the Featherwing Coop can be also unlocked with the wide windmill.

I will have more of these in the future to unlock.

@Faxu I tried your solution by not expanding and only getting 2 tech and it worked. I'll be sure to add your name to the guide. :)

For "Firetower Hearth" i didn't place banners and only win with two technologies. Probably this last is the solution
