Prepare the Ship Before the Final Wave

Hull Rupture’s wave 20 boss is a test of the economy and defenses you built during the run. Prepare weapons that can keep attacking along its approach, maintain the resources needed to upgrade them, and leave the Airlock as a final defensive layer. A recorded demo victory provides a useful example with upgraded lasers and sniper-style defenses, but it is not a guaranteed shopping list for every run.

The demo changed substantially in September 2026. Older recordings can illustrate a successful defense without establishing current kit prices, balance values, or ship-expansion steps.

Build the Production Behind Your Guns

The official September demo update explains that Microchips and Nanobots became easier to reach, while the final boss still required substantial investment in good turrets. Getting an advanced weapon kit is therefore only part of preparation: the ship needs to produce the materials that let you build and improve the defense.

Look at the weapon upgrades you can actually support. If a valuable turret needs a resource your ship barely produces, consider the production gap before spending everything on unrelated expansion. The same economy also has to support the ship’s workforce and propulsion.

The developers emphasize turrets as the main defense, with Airlock units as backup for enemies that get through. Older unit-heavy strategies should be read against the September changes, which weakened some of those combinations and added more turret interactions.

Give the Boss a Useful Route to Travel

The October 22 Hull Construction deep dive places bosses at the far upper-left part of the ship, away from the Airlock. Its recommendation is to give them more distance to cover. A longer route is valuable when defenses have opportunities to fire along it, not simply because the hull is larger.

Match weapon range to the positions you create. The developers recommend open areas and exposed corners for long-range turrets, while short-range weapons can benefit from enclosed sections. Check the actual route toward the Airlock before committing your most important firing positions.

Avoid planning around repeatedly moving the same turret ahead of the boss. The September update says relocation takes time and leaves the turret inactive afterward; that delay was introduced specifically to discourage following a boss along its route with the same weapons.

What a Recorded Demo Victory Supports

In the recorded Hull Rupture demo run, the player reaches wave 20 with a developed economy and several upgraded defenses. Their commentary identifies one large boss approaching from above, then describes lasers and cross-map snipers dealing substantial damage while the boss is slowed.

That is player experience from the recorded demo. It supports long-range coverage and upgraded weapons as a workable example, not a universal minimum damage value or proof that a specific turret is mandatory. The player also runs short of Minerals for an additional unit upgrade during the encounter, illustrating why late preparation still depends on resource supply.

Use the example as a planning check: can your strongest weapons reach the approach, are useful upgrades already funded, and is there a backup if the boss gets close? Adapt those questions to the kits and modifiers your run supplies.

FAQ

Which wave contains the demo’s final boss?

The recorded run identifies the large boss at wave 20. Its player defeats that boss before discussing play beyond the demo’s normal objective.

Do I need the exact lasers from the recording?

No mandatory loadout is established. The recording demonstrates one successful setup; the official guidance emphasizes strong turrets supported by a functioning economy and useful firing positions.

Where should I plan the boss route?

The October construction devlog describes the boss landing at the far upper-left part of the ship, furthest from the Airlock. Plan defensive coverage along the resulting approach.

Should I move every turret as the boss passes it?

That is not a reliable continuous-fire plan in the updated demo. Moving takes time and creates downtime, specifically limiting that tactic.
