The project is a fan-made, pure-Python implementation with no external dependencies. + +## Core Goal + +Provide a faithful, playable recreation of the Fallout hacking minigame in a terminal environment, where the player must deduce a master password from a set of candidate words within a limited number of attempts. + +## Gameplay Objective + +1.

The player must guess the correct word within a limited number of attempts (`candidates / DIFFICULTY`). +4. After each wrong guess, the game provides a hint: how many letters from the guess appear anywhere in the master password (e.g., `2/5`). +5. The player wins by guessing the correct word before running out of attempts. + +## Design Goals + +- **Authenticity**: Mimics the retro terminal aesthetic of Fallout's hacking sequences, including themed output messages and a simulated loading effect. +- **Simplicity**: Pure Python 3, no external dependencies — runs anywhere Python is installed. +- **Configurability**: All game parameters (word list, word length, attempt count, difficulty, visual delay) are controlled via `config.json`. +- **Extensibility**: Supports any language by swapping the word list file (one word per line). +- **Code quality**: PEP 8 compliant, enforced via `flake8` and automated CI/CD checks. + +## Technical Scope + +| Concern | Approach | +|---|---| +| Language | Python 3.x | +| Word source | Plaintext file (default: Italian, 40k+ words) | +| Word filtering | Words are filtered to an exact configured length | +| Hint system | Letter-overlap count between guess and master password | +| Difficulty | Attempts = `floor(num_candidates / DIFFICULTY)` | +| Configuration | `config.json` — no code changes needed to tune the game | + +## Out of Scope + +- Graphical or web-based interface +- Networked or multiplayer modes +- Ownership of the Fallout trademark (this is purely a fan project) From 4852c90557e8cd84c30c9666e743e44e6c87c998 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 15 Mar 2026 12:46:57 +0000 Subject: [PATCH 2/4] docs: add GAMEPLAY.md with full session trace and mechanics Documents startup sequence, word list generation, attempt calculation, the letter-hint feedback system, both win/lose end states, a real session replay, config reference, and strategy tips. https://claude.ai/code/session_01MQnNXtMmBiQvwoFoNdEQDb --- GAMEPLAY.md | 191 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 191 insertions(+) create mode 100644 GAMEPLAY.md diff --git a/GAMEPLAY.md b/GAMEPLAY.md new file mode 100644 index 0000000..f1c7515 --- /dev/null +++ b/GAMEPLAY.md @@ -0,0 +1,191 @@ +# Gameplay Documentation + +## How to Run + +```bash +python3 main.py +``` + +No external dependencies required.
