Hyperloop Bugfixing and Resource Stock QOL update

2026-05-12

Hello Terraformers! Today, we bring this bugfixing & QoL update, which should improve the overall experience of Per Aspera. Drones will behave better when using hyperloops, and you will now be able to click on the custom resource stock fields to manually modify the values. Thanks to the community for bringing up these issues. Ad Astra! - Tlön Industries Changes - QOL: Players can now manually set up the custom resource stocks. Fixes - Fixed: When a hyperloop is finished, drones crawled to the other side, rather than using the new terminal. - Fixed: Some cargos were stuck for a long time in hyperloop terminals, causing bottlenecks in construction sites. - Drones now crawl back at 50% speed

I like space games. I like colonising planets and terraforming them. I like city builders. So how come I didn’t like this game? • Pacing. The game is 90% waiting. And I mean waiting at 16x speed, the maximum this game allows, still feels extremely slow, as everything takes an absolutely insane amount of time.

TL,DR: This is no managerial base building sim, it's an idle game with some cliché graphic novel elements. Almost non-existent challenge, very few...

It's kinda cool as always to terraform a planet but there's no depth to this game. The gameplay is super boring. You place buildings, maybe prioritize one or two, then wait. The logistics are kind of annoying, it's all automated and there's no way for you to specify which materials get transported where. You have to build a crap ton of worker drone hubs. They call them hubs, but you literally have more of them...
