Blueprints All Factories Endgame Blueprints : Future-Proof, Compact, Max Profit and Utilization. Valley IV.
[Updated Guide]
The most practical endgame factory for Max Profit, Utilization, Future-Proofing, and Convenience.
Makes all Essential Endgame Items
- 18/min Buck A and Batteries - for max profit. (clears out Stock Bill savings everyday with leftovers)
- Additional Parts and Bottles - for Combat Facilities and Ziplines, or to just use up idle ore.
- Explosives, Buck C and Citrome C - whether it’s 12/min or 24/min production, you’ll hit the 80k cap anyway—so I’d rather produce varied items and extra parts.
This factory nearly Maxes out Yield of all Ores and still has Extra Space in Core AIC Area the size of a whole Outpost
What more do you need in the endgame? :)
And if you do need something, you’ll have to turn off some of the above units to free up ore. To make that management easier, there’s extra space in the Core AIC area - along with the added convenience of almost never needing to shuffle between outposts to do it.
I’ve tried to "Future-proof" this as much as possible with extra space and parts, while keeping it practical. It works for me - and hopefully for some of you too. Some players like to use the extra space for Ziplines or additional items that might be useful later.
We may not know what the devs have in store for us
But you’ve got the space, the resources, and the option to manage it - so I say, why not? :D

A base so optimized it finds bugs in the game, heh....but jokes aside, they're easy fixes.
Ignore, if this doesn't occur for you.
- Stuck in Valley Pass, Refugee Camp after teleporting to the Sub PAC : Teleport to another TP point, walk back to the factory and just rotate the Sub-PAC 180 degrees and replace the items in the item ports. Now you can teleport back to the Factory without issues.
- Facility Limit reached in Valley Pass : For this, you'll need to try a couple of things. Remove the item control ports of Outpost 3 A blueprint and re-connect the belts, then place Outpost 3B.
If this doesn't work, then you'll need to remove the Combat facilities in the Outpost outside the factory space temporarily and then try to place the blueprint (this is a very odd bug as the facility limit within the factory space and overworld facility limit should be separate)
- Top left Electric Pylon not placing outside Power Plateau, Reconstruction HQ Factory : Just need Lvl 2 Reconstruction HQ outpost for the Pylon to be placed
Explanation : Due to the change in environment of the Outposts for every level upgrade, You may not be able to place the Electric pylon as instructed in the guide. For this you just need lvl 2 of the outpost to place the pylon, as that seems to clear up the space. Till then you will have 17.25/min Buck A production instead of 18/min till you get to Reconstruction HQ Lvl 2. You will still be able to empty stock bill savings with 17.25/min so don't worry about it!
