This add-on is for players who want to support a solo dev and get a set of behind-the-scenes extras. It is not a gameplay expansion. Nothing in Meco is locked behind this DLC.

What you get today

• Original soundtrack: 9 tracks as MP3 files (around 220 kbps), the same music that plays in the game.
  
• 5 reference PDFs on turbomachinery and engine design (NASA and NAVAIR reports, 1967 to 1974). These are the public-domain documents that informed Meco's turbopump and turbine modelling. They are free to download from NASA's own archive. This DLC collects them in one place, it does not give you access you would not otherwise have.
  
• 3D-print files: 2 showcase turbopump geometries, a Vulcain-style LH2 impeller and a turbine rotor with stator, each supplied as STL and 3MF. Desk models for display, not engineering parts.
  
• 4 hi-res "Miku" wallpapers (Meco's mascot and guide).

You must own Meco Rocket Simulator to install this content.

How this content was made
The wallpapers and the soundtrack were produced with custom-trained AI tools, from assets I own or created. The simulation and engineering systems in Meco are hand-built and physics-based. The reference PDFs are third-party public-domain documents, reproduced as published.

Still in Early Access
This DLC will grow, and anything added arrives free for existing owners. What I intend to add, in no committed order and with no promised date:

• Export of 3D-print files for turbopump, nozzle and injector parts you design in game
  
• Scriptable custom components
  
• Scriptable custom UI

Treat that list as intent, not as a schedule. If the scripting work ships, it ships here. Buy this DLC for the contents above and for the support, not for the list.
