Thrusters needed to be placed with zero space in-between in either a \ or / with one tile of width dedicated to piping in the fuel/oxidizer.


Actually you can squeeze 25% more thrusters if you don't have a gap between them (f you really need the marginal speed gain).

Aiming for exact ratios is chasing rainbows. Due to rounding errors, machines will be either slightly too fast, or slightly not fast enough. Either backed up belts, or insufficient throughput belts.

if Factorio, it's a good idea to always produce more than you need, be it by +1%, +25%, +300%. This ...

I did some testings with my promethium ship configurations. Stats: 30 tiles wide, 380 tons, 3 thrusters (1 legendary and 2 epic) throttled based on tank/pipeline volume.
My top speeds were previously 240km/s or 280 km/s in 2.1.20
In 2.1.21, my top speeds became 207km/s or 238km/s. That's around 15 ...

Nice update, the decision to change drag is interesting, and I welcome new circuit options.


Minor Features

Added quick pipette: pressing key related to empty quickbar slot will invoke pipette and set the slot with the pipette result.



How about enabling pipetted items (or ghost items) to ...

if not using artillery, legendary rocket turrets also out-ranges behemoth worms by 6 tiles (range 54 vs range 48).

There's different strategies that a crafting machine could use (i.e. lowest first, highest first, non-mixed first), but I think the most intuitive here would be to use the higher quality ingredients first. You typically want a machine to craft the ...

The issue with this approach is handling ingredients in 5 different stacks, each. Also, deciding which ones to use for the craft.

But I agree, it would have been easier to use quality.

I was copying and pasting lamps (over the same lamps) just to change the color. However, I cannot paste a lamp above this existing lamp, due to the tree being too close.

The tree was planted before [2.1] so maybe the seed/tree hitbox was smaller than in the current version.
The beacons are also ...

Counterpoints:
In real life, power demand is regulated by power generators (turbines, etc.), not by accumulators. Also, buffing accumulators too much may create an imbalance between solar panels and accumulator ratio, in common setups.

A good middle ground could be: keeping the capacity and Max ...

Unpopular opinion: those complaining are the vocal minority / sheep effect.

To those having a problem with how it works in 2.1.8, let's consider this angle: If you are producing enough fluid, your fluid systems will be at least 10% full, and no machine will starve. Heck, it could even be 97.4 ...

Update: this also happens in 2.0.76. The power consumption increases with the shooting speed. However, it doesn't explain why the power spikes are not matching the turret's attack, and the double/triple beam when attacking large asteroids.

What did you do?

In April 2025, Kovarex hinted a bunch of new achievements for 2.1, or an achievement for getting all achievements in the same run and/or a 100% run mode.

I agree that this would be very fulfilling for hardcore gamers (or professionals): the ...

Love all the new features and graphics!

The infinite research! The circuit options, the Landing pad unloading bay, the planets! The new Oil refinery, graphics, the new Assembling machine (we were so used to that basic box, looks much better now!)

Hopefully some minor QOL features will still be ...

You can use asteroid productivity research, with the 20% asteroid output in the normal crushing recipes. With enough research, you reach the same 80% output...

So there you go.

(although I think asteroid productivity shouldn't increase the chance of asteroid chunk output, that's like having ...

Even before Space Age, I had to build tons of accumulators to handle nuclear / grid demand. The ratio transmission / capacity has always been a bit low.

Especially given that 1 turbine = 20 accu (power transmission), and given that nights on most planets are shorter than days, I think that doubling ...

If you optimize your recycling loops, you can get closer to 1 legendary per 21 item consumed for cryogenic plant and 1:37 for EM plant, without any productivity research.

With productivity research (blue circuit, LDS) you can get almost 1 ...

Using quality modules when reprocessing asteroid (AKA "space casino") rolls quality while only removing 20% of the resource, unlike the intended method, which normally removes approx. 50% of the resource per quality roll.

Minus 20% vs 50% per quality roll (or 35-45% if using foundry/EM plant ...

I love the changes, all of them. (And I think blue circuit shuffle is even stronger than LDS shuffle, as it allows to get 1 legendary green/red circuits per normal green/red circuit, or 30-40% legendary iron plate and 10-15% legendary copper plate per normal iron & copper).

In this screenshot, I can "drop" the held ghost (or item) in the circuit slot, but I cannot drop it in the recipe slot (because there is no recipe slot, really I would like to drop it in the bug UI on the left ...

The way I see it, it would only update the recipe if the item/ghost is dropped in the checkbox area.
