The laser cannon is the final construction project in The Crust, and it is the one quest where the game's own interface and the developer's patch notes use different names for the same thing — "Laser gun" in the mission log, "laser cannon" in the announcements. Both are official. More practically: the shipped 1.0 build builds it in seven stages, and the widely-cited community wiki still documents six, because its quest page is tagged version 0.93.22 and predates launch by months. The stage structure below comes from the game's own screen; the per-stage costs you will find elsewhere do not.

Two names, both official, in different layers

This is the first thing to settle, because it decides which searches will help you and which will waste your time.

The game’s interface calls the quest “Laser gun.” That is not an inference — it is the literal text in the mission-log panel of the 1.0 screenshot on this page, alongside the objective “Prevent the catastrophe 4/7” and the current step “7th stage.”

The developer’s written communication calls it the laser cannon. Searching all 147 posts in the official announcement history for app 1465470 returns:

Term Official announcement hits
laser cannon 31
laser 35
stage 20
trigger 4
laser gun 1
turbo laser 0
catastrophe 1

That single laser gun is the interesting number, and it is not noise. It appears in Patch v0.92.35 of 16 July 2024, in quotation marks, referring to the quest rather than the building: “CRUST Solutions now opens before starting the "laser gun" quest, after completing the main story.” In one sentence the developer used the interface’s name for the quest while continuing to use “laser cannon” for the structure everywhere else. That is the whole naming split, visible in a single line.

The lone catastrophe is a different sense of the word entirely — a market scenario in a developer diary about trading, not the quest objective the mission log shows as “Prevent the catastrophe 4/7.” So the pattern holds: the interface names the quest, and the notes name the building. The community wiki handles the same split by giving the quest a page titled “Laser Gun” and pointing “Laser-Cannon” at it as a redirect, which is a reasonable compromise and also a sign that the wiki maintainers noticed the same discontinuity.

The practical upshot: if you have been searching “the crust laser gun stages,” the pages that match may be describing an older build, because that phrasing correlates with the interface rather than the notes. If you have been searching “laser cannon,” you will find patch notes that never mention the stage count at all. Neither term alone gets you the structure — which is what the rest of this page provides.

The stage count: 7, not 6

Here is where the highest-tier evidence beats the most-cited source, and it is worth showing the discrepancy explicitly.

A 0.93.22-tagged community wiki page documents the build as six stages followed by an activation step:

Wiki stage (v0.93.22) Action
1 Lay the foundation
2 Create infrastructure
3 Install the power supply systems
4 Assemble the laser system
5 Install the targeting system
6 Calibrate the laser system
+ Activate the laser cannon — 3 × Engineer Level 3, 1 × Scientist Level 5

The shipped 1.0 build disagrees on the numbering. The mission log shows a progress counter of 4/7 and labels the current objective “7th stage”, reading “Install the targeting system.” Two independent readings on the same screen point to seven stages, and they place the targeting-system step at position seven rather than position five.

That is not a cosmetic difference. It means at least one stage was inserted ahead of the targeting step between 0.93.22 and 1.0, and it means every resource list that assigns costs to “stage 5” is now attributing those costs to a different piece of the build. We are not publishing the wiki’s per-stage quantities for exactly this reason — not because we distrust the wiki’s structure, but because a version tag of 0.93.22 makes the numbers unusable against a 1.0 build.

There is one more piece of corroboration, and it is the kind you only get from reading patch notes closely. Update 3 records fixing “an issue where the Laser Cannon did not progress to stage two.” That is the developer using the word stage for this quest’s construction phases in their own writing. So the staged structure is official, the word is official, and only the count comes from the screen. Anyone who tells you the quest is a single delivery of one resource list is working from a build several versions out of date.

Before the quest exists, three things have to happen. The community wiki lists them as:

  1. Build the Repeater
  2. Find and repair the Mobile Drilling Rig
  3. Complete a special SCT contract

The wiki appends a practical warning that explains most “the quest never started” reports: “There may be delays between each quest triggering.” That is worth internalising because it means absence of a quest marker is not evidence of a missing prerequisite.

Not all three links are equally evidenced, and the difference matters. The Repeater and the MDR steps rest on the wiki alone at this tier. The SCT contract is different: a 0.99.93 hotfix records fixing “a bug where contracts from SCT Ltd wouldn’t appear,” which independently confirms that SCT Ltd is a real entity with real contracts in the game and that those contracts have previously failed to display. When a wiki lists a prerequisite that a separate official source confirms exists and has malfunctioned, the prerequisite becomes considerably more credible.

The broader rule this illustrates: a quest gate is invisible until it breaks. Quest chains rarely appear in patch notes as features, only as defects. So the announcement history is a poor tool for learning what gates a quest, and a good tool for confirming that a gate you read about elsewhere is real.

What the aid mechanic actually is, and why 1.0 changed it

The most important thing to understand about this quest is that you are not supposed to fund it alone — and how much help you get is now a reputation outcome.

The mechanic was introduced in stages, and the official text tracks it clearly. In the June balance update, the developer addressed a community complaint directly:

Many players have rightly pointed out that the space community seems in no hurry to help save Earth from the impending disaster, preferring to leave the task entirely to the player. We agree that the organizations are acting, to put it mildly, unreasonably, so we’ve added support in the form of useful material deliveries for the early stages of the laser cannon. At the game’s full release, this mechanic will be expanded and refined to make the quest feel more dynamic and varied, and deliveries will depend on your reputation.

The same update’s patch notes describe the first version as “minor help from the organizations in the laser-cannon construction quest” and add a candid parenthetical — “(spoiler: this isn’t the final version of the quest’s assistance).”

Then 1.0 shipped the final version, and stated the rule plainly: “How many Organizations will help with building the laser cannon and the interstellar ship, and to what extent, now depends on reputation.”

Three consequences follow, and they change how you should play the mid-game.

The quest is a reputation sink before it is a resource sink. Deliveries now scale with standing, so the organisations you cultivated earlier are the ones that reduce the build’s cost later. A player who ignored faction reputation has effectively chosen the hardest version of the final quest.

Two late projects share the same lever. The same sentence covers “the laser cannon and the interstellar ship,” so reputation is doing double duty. Investing in it once pays out twice, which makes it a better buy than it first appears.

Aid is a mechanic that can break, and has. Hotfix 1.0.10 fixed “an issue with one of the faction assistance objectives during the construction of the Laser Cannon.” If you are on an older build and an assistance objective will not complete, that is a known defect rather than a step you are performing wrongly.

Reading the current objective

The 1.0 mission log gives you more actionable structure than a stage number does, and it is worth knowing what each line means.

The panel shows three nested pieces of information. The quest title, “Laser gun,” is the top level. Below it, “Prevent the catastrophe 4/7” is your progress through the stages. Below that, the current objective reads “7th stage — Install the targeting system,” with the instruction “Send the necessary resources to complete the laser system construction.”

Two details in that layout are worth noticing.

The delivery verb is “send,” not “build.” Every stage instruction in both the wiki and the interface uses the language of shipping resources to the project rather than constructing modules yourself. This is consistent with the aid mechanic: the project is a consortium build you are supplying, not a structure on your own grid. It also explains why the Launch Station and transport systems matter to a quest that has nothing visibly to do with either.

The stage description changed between versions too. The wiki’s fifth step reads “Send the necessary resources to complete the fifth stage of construction” — a description that names its own ordinal. The 1.0 interface reads “Send the necessary resources to complete the laser system construction,” naming the system instead. When a description stops referring to its own number, that is often a sign the numbering itself has been reworked, which is consistent with everything else on this page.

Community-tier claims, clearly labelled

Two claims on this page rest on the community wiki alone, and you should weigh them accordingly. Both come from a page tagged version 0.93.22, months before launch:

  • The full prerequisite chain — Repeater, then MDR repair, then the SCT contract. The SCT half is corroborated by an official hotfix; the other two are not corroborated at this tier.
  • The deadline warning: "This is a timed event and you will fail if the time runs out. Plan accordingly." We searched the official announcement history and found no matching statement. A staged quest with stalled-progress fixes is consistent with a timer, but consistency is not confirmation.

We have deliberately not reproduced the wiki's per-stage resource quantities. A 0.93.22 cost table against a 1.0 seven-stage build would be wrong in both the amounts and the stage they apply to.

If you only remember one thing

The laser cannon is the point where your reputation with the in-game organisations converts into construction resources. Official 1.0 text ties both late-game megaprojects to it. So the question "how much will the laser cannon cost me" has a player-controlled answer — and it was decided long before you reached the quest.

Where this leaves you

Three things to carry forward. The name is ambiguous but the destination is the same — search “laser gun” or “laser cannon” and you are looking for the same quest. The build is seven stages in the shipped version, and any six-stage breakdown you find is running on a 0.93.22 tag from before launch. And the cost is negotiable through reputation, which is the one lever that turns this from a resource grind into a decision you made hours earlier.

What we cannot give you is a current per-stage resource list. No official source publishes one, the interface shows progress rather than totals, and the only community table we found predates launch. Rather than hand you numbers from the wrong build, we have left that column empty and told you why.
