Frontier Bridge — 7 Days to Die × Subsistence
Status: source/design draft; not a playable or publishable release.
Frontier Bridge is intended to connect the real crafting and progression of two owned games without shipping either game's files. Melty currently requires 7 Days to Die as the primary launch host; Subsistence is not in Melty's catalog, so it cannot be a Melty-managed companion or the first game in a guaranteed one-click launch. This draft therefore does not claim to transfer items between game inventories or to alter either game's saves.
Current milestone
- Catalogued a small set of Subsistence crafting recipes from the public Subsistence Crafting Guide.
- Established a preflight validator that refuses to mark mappings complete until the actual installed 7 Days to Die XML identifiers and local Subsistence installation are verified.
- Added an empty, non-invasive 7 Days to Die modlet shell. It makes no gameplay changes yet.
- No game assets, executables, extracted files, credentials, or proprietary content are included.
Design rule
A cross-game mapping is not implemented merely because two items have similar names. Each mapping needs a verified source item/recipe, a verified target item/recipe from the player's installed game files, and an explicitly implemented transfer/conversion mechanism. Until that mechanism exists and is tested in-game, the mapping remains proposed or blocked.
Local preflight
Run from this directory with Python 3.10+:
python scripts/preflight.py --seven-days "C:\path\to\7 Days To Die" --subsistence "C:\path\to\Subsistence"
The script checks required install files, parses local 7 Days to Die config XML, verifies mapping identifiers, and reports blockers. It does not change either game or save.
Known constraints
- The user's Windows game installations are not mounted in the current build environment, so local item IDs, game versions, Steam libraries, and real launch behavior have not yet been verified.
- The Melty API was unreachable from this environment (DNS resolution failed); no Melty project was created, inspected, uploaded, or published.
- Multiplayer networking between two separate games has not been verified. This draft does not declare multiplayer support.
Credits and permissions
- Game content remains the property of the respective game publishers. The project distributes no game assets.
