# Limitations

Fallout 4 was designed as a single-player game. Fallout 4 Together is therefore expected to have serious technical limitations, especially during early development.

## Early Prototype Limitations

The first prototype will likely require:

- All players to remain in the same test cell
- A clean Fallout 4 test profile
- A dedicated test save
- No large gameplay mods
- No quest synchronization
- No settlement synchronization
- No VATS synchronization
- No dialogue synchronization

## Systems Not Supported Early

### Quests

Quest state is complex and deeply tied to the single-player game world. Quest synchronization is not part of the first prototype.

### Settlements

Settlements involve workshop data, placed objects, NPC ownership, resources, attacks, and persistent state. Settlement sync is not part of the first prototype.

### VATS

VATS depends on single-player time behavior and targeting logic. VATS should be disabled or ignored during early tests.

### Saves

Multiplayer state may desync or damage saves if handled incorrectly. Use a dedicated test save only.

### Mod Compatibility

The first prototype should be tested with a clean setup. Compatibility with large modlists is not an early goal.
