Hull Rupture Hard difficulty unlock guide

Unlock Hard on the full release

1. Update the full game. The shared difficulty rule arrived in 1.0.15. It is part of the full-release patch sequence.
2. Start a Classic run on Normal. This is the specific route Konfa Games gives for unlocking Hard.
3. Complete Classic. The launch guide describes Classic as a 20-wave run. Surviving the wave 10 boss is a midpoint.
4. Check your next run setup. Choose a mode you can already access and look for Hard in its difficulty choices. You can return to Classic to check whether Hard is available there too.

What you want to open	What the Classic Normal clear does	What to check
Hard in Classic	Unlocks the difficulty	Check the difficulty choice when setting up a fresh run
Hard in another available mode	Shares the same difficulty unlock from 1.0.15	Select the available mode, then check its difficulty choices
A mode you have yet to unlock	Leaves the mode’s own requirements in place	Check the mode’s progression conditions
An achievement tied to a mode or run	Leaves its original conditions in place	Read the achievement requirement and complete that task

Prepare for the Classic clear

Keep the ship moving and protect Despot’s Chamber. If Despot’s HP reaches zero, the run ends. Between waves, the galaxy route offers shops, encounters and resources. Base your next stop on the problem likely to end the run. Check for a weak approach to the chamber, a production shortage or an underdefended route to the airlock.

• Trace the route before building. Hull blocks shape the path aliens take toward the airlock. Look at where an added block would send them and whether your defenses can cover that path.
• Review the layout before wave 8. In 1.0.15, waves 8 and 9 became slightly tougher. The wave 10 boss has less health and heals less. Prepare for the whole stretch, then use the midpoint to reassess what the second half of the run needs.
• Treat the shop as a choice. Patch 1.0.15 made kits that produce Uncommon resources slightly easier to find in the first three post-combat shops. Use what actually appears to cover a bottleneck before committing to a production chain that depends on a particular kit.

Hard is still missing, or the mode is locked

If Hard is missing, first check that you finished a Classic Normal run on the full release, then check it in Classic and another mode you can already select. If the mode itself is locked, follow that mode’s progression conditions. Konfa Games separated Endless from Classic for the full release, so finishing Classic will no longer roll the same run straight into Endless.

If a new run started before you finished another one and the galaxy map failed to generate afresh, check for 1.0.16. That hotfix addresses map generation. If a completed Normal clear still leaves Hard missing on the current build, record the mode, selected difficulty, end-of-run screen and game version when reporting it.
