The short version

Sludgineers is one of the friendliest completion lists on Steam. There are 25 achievements, nothing is missable, and achievement-hunting coverage rates the difficulty at 1 out of 10, noting that most unlock just by playing through the game.

Practically, this means you do not need a checklist open while you play Sludgineers. Play the game normally, finish the progression, and check what has not popped at the end. Anything outstanding will be a cumulative counter you can still fill.

What the 25 achievements cover

Exact achievement titles are being compiled from play — we do not publish invented names. What the game's structure tells us with confidence is the shape of the list. Sludgineers is built from a handful of measurable systems, and achievement sets in games like this track those systems:

Likely categoryWhat it tracksWhere it happens
ProgressionUnlocking regions, reaching map milestonesRegions
Cleaning totalsCumulative sludge cleared, jobs completed at 100%Job loop
Cash milestonesTotal earned, single-job totalsMoney guide
Upgrade purchasesBuying into branches, maxing node ranksUpgrade tree
RefiningBarrels processed, refinery automation reachedRefinery
QuestsQuest completionsQuests
ToolsUnlocking drones and air purifiersDrones
Object huntingUncovering scenery for Object BonusesMoney guide

The 100% route

  1. Play Sludgineers normally to the end of progression. Unlock every region, buy out the upgrade tree, automate the refinery, get drones and air purifiers online. This takes roughly 4–5 hours and will pop the large majority of the 25.
  2. Clear the quest board. Quests are cumulative and pay cash, so finishing them is profitable regardless. See quests.
  3. Check what's left. Open the achievement list and look at the unpopped entries. Because nothing is missable, every one of them is a counter.
  4. Replay a high-value job to fill counters. The REPLAY button on the Job Complete screen makes this painless. A late coastal job with $8,525 in its top tier fills cash and cleaning counters far faster than an early forest job. See the payout curve.
  5. Finish object-hunting counters last. Dense town and industrial scenes have the highest object counts, so re-run those with full gear and a Magnet if you have one.

How long 100% takes

About 5–6 hours in total. That is the completion figure reported by achievement-hunting coverage, and it matches Sludgineers' structure — a finite tree, a finite region list, no prestige loop and no New Game+ to extend the run. See how long Sludgineers is.

For context, a difficulty rating of 1/10 with 25 achievements at 5–6 hours puts Sludgineers firmly in “pleasant weekend 100%” territory. There is no grind wall and no skill gate.

Achievements and the free versions

Steam achievements only unlock in the paid Sludgineers release. The free Steam demo is a separate app and does not carry the 25 achievements, and the itch.io browser build is outside Steam entirely. If you are hunting the completion, you need the full game.
