Hull Rupture Hull Construction: Placement Rules and Empty Slots

Which building rule changed at release?

A completed adjacent module is no longer required to build in an empty module slot. Konfa Games explicitly removed that demo rule for the full release. If you are following an old tutorial, stop using neighboring completion as your explanation for an unavailable placement.

First distinguish the object you are placing: a hull block expands the ship’s frame; a module occupies space inside it. The permanent block rules below do not mean every module fits every opening.

What should you check before placing a hull block?

The October 22 construction breakdown documents a mode that automatically pauses flight while you choose a location for a randomly offered block. It describes 15 construction blocks in a randomized cycle, with no repeat until that set has been used.

Check these constraints before committing:

Check	Why it matters
Orientation	Offered blocks cannot be rotated
Airlock and engine	New construction must not obstruct them
Available interior space	The shape must suit the module kits you intend to use
Enemy approaches	An extension changes the route toward the Airlock
Commitment	Placed hull blocks cannot be destroyed
Resources	Building and skipping both have a cost

The September explanation says construction initially uses Energy and later Plasteel. Read the displayed cost for your current offer; no fixed price schedule is established here.

This is a decision checklist based on the developer’s construction documentation, not an interactive blueprint solver. The November launch FAQ overrides the old adjacency rule in those earlier explanations.

Can you make a corridor outside the ship?

The developer describes attaching a block to a side of the hull or placing it a short distance away on stilts. The offset creates a corridor that aliens can traverse. That corridor changes your firing opportunities, rather than simply adding production space.

Before choosing it, compare two outcomes:

• A compact shape keeps more modules together for adjacency effects and reduces crew travel.
• A longer shape can stretch the invaders’ approach and create different firing positions.

Neither is automatically best. Match the shape to your available equipment and economy. The turret and alien-route guide explains the range and lane trade-off; crew allocation covers why travel and available workers also matter.

What if a module still will not fit?

Check the actual module footprint, whether the target space is empty, and the kit and resources shown by your installed game. The release’s any-empty-slot rule removes adjacency gating; it does not promise that all equipment fits all spaces or costs nothing.

If the UI rejects a placement that appears valid, record the module, hull shape, visible cost and rejection message. Include a screenshot in the official discussion area. Do not demolish unrelated modules on the assumption that an old demo rule is still active.

Returning players can use the demo return checklist to separate this change from artifact resets and mode progression.
