VISUAL EVIDENCE

Patch #1 is small in line count and big in impact because it targets the exact bottleneck launch players were already reporting: late-game Draxine and waiting on the refinery.

Refinery processing can go lower

The patch added an additional refinery-processing upgrade at the bottom of each refinery tree. According to the official notes, the previous minimum 120 seconds can now be upgraded to 90 seconds, then 60 seconds at level 2.

That changes the recommendation for players who are genuinely returning from a job before their refined resource is ready: processing speed now has another meaningful step.

Late-game Draxine costs reduced

Higher-tier / late-game upgrade Draxine costs were reduced by roughly 10% across the board.

This is the patch note that directly addresses the launch-week “I have cash and other resources, but Draxine is still gating me” complaint.

Drone Capacity and Speed got cheaper

The Draxine and money cost of Drone Capacity and Speed upgrades was reduced by roughly 30%.

That makes old launch videos a poor source for exact drone prices. Use the current in-game tree, not screenshots recorded before v1.00.01.

Safes now pay much more refined material

Refined Resources earned from Safes increased by 250%.

That is a huge change to the value of safes in late progression. They were already tied to safe/diamond achievements; now they also help feed refined-resource demand much more aggressively.

Patch #2 (v1.00.02, August 30) made safes pay even more

Official late-game economy notes, not a guess:

  • processing Yield upgrades at the bottom of refinery trees: previous max 20 now goes to 24, then 28;
  • more coins from safes per upgrade level;
  • higher chance of diamonds and gold coins from safes at max upgrade;
  • higher barrel cash and final-level job-complete cash.

If a launch-week video still treats diamonds as a rare side drop, it is out of date. Patch #2 also added a Level 1 freeze workaround when Steam fails to initialize (achievements/cloud saves can stay offline until the retry reconnects).

Patch #3 (v1.00.03, September 2)

Patch #3 (v1.00.03, September 2) is live. Official notes focus on Steam Deck input, keyboard menus, a refinery barrel visual glitch, Turbo Time achievement cleanup, sludge-detector threshold, and saved zoom on the upgrades/map popups. The 120Hz Mac issue is still not resolved.

The developer’s thank-you post says the next design work is end-game Challenge / Modifier modes, not a new biome. Treat that as a plan, not a live feature.

Patch #4 (v1.00.04, September 15) — the Resource Exchange

The first patch that adds a new system rather than tuning an existing one.

  • Carl’s Amazing Resource Exchange was added, unlocked in Region 6 (City Levels). Open it by clicking the Region Exchange on the map or from the top HUD.
  • At the Exchange you can buy or sell resources to get what you need for upgrades, rather than waiting on a region’s natural output.
  • Two new quests improve your buy and sell rates. They are located in regions 6 and 7, so the Exchange is worth revisiting after you progress.

What the developer says comes next: after a break, the team is back and Update 1.01.00 is in the works — the stated focus is improving the fun, variety and rewards in the end game on the way to 100%. They describe it as a fairly substantial piece of work still in its design and concept phase, with no ETA — planned, not imminent. The same October 6, 2026 post celebrated crossing 100,000 sales in just over a month, with over 1,800 Very Positive reviews.

What this means for guides

Any guide that publishes a pre-patch refinery time, late-game Draxine cost, drone capacity/speed cost or safe refined-resource payout without a version label can now be wrong two days after release.

This site therefore treats v1.00.04 as the current patch baseline and labels older video numbers as historical rather than silently copying them. Patch #4 changed the resource economy rather than any of those numbers, so the earlier labels still hold.
