Secret Neighbor Cheat Client

I created a multifunctional cheat client for the game Secret Neighbor, which operates on the basis of MelonLoader — a universal mod loader for Unity games. This project became my deep dive into reverse engineering, memory analysis, and creating complex UI solutions for game clients.

Technologies I used
Programming Language: C# (.NET Framework)

Platform: MelonLoader (mod loader for Unity)

Libraries: Harmony (method interception), UnityEngine.UI (UI creation)

Tools: DNSpy (reverse engineering), Unity Explorer, Visual Studio

Additionally: Working with process memory, code injection, network packet analysis

Key Features
1. Player Management
Buff Me / Buff All — applying buffs to yourself or all players

Stun All — stunning all players on the map

Ghost Mode — ghost mode (invisibility and passing through walls)

Neighbor Transform — instant transformation into the main villain

Teleport All Players — teleporting all players to yourself

2. ESP (Visual Enhancements)
Player ESP — displaying all players through walls with distance and 3D boxes

Neighbor ESP — highlighting the neighbor in red

Items ESP — displaying all items (keys, maps, weapons, medkits)

Fullbright — full lighting of the map (night vision)

Show Distance — displaying distance to objects

Show 3D Box — 3D frames around players and items

3. Game Event Management
Force Start — forced game start

Trigger Mayak / Rocket — activating special events

Break All Windows — breaking all windows on the map

4. Game End Management
Neighbor Win — instant victory for the neighbor

Kids Win — instant victory for the kids

Time Is Up — game ends when time is up

Unlock Basement Door — opening the basement door

5. User Interface
Developed a convenient and stylish interface with categories

Added hotkeys for quick access to functions (Z, X, C, R, J, Insert)

Implemented the ability to hide/show the UI with one button

Integrated a settings system that is saved between sessions

Complex Technical Challenges I Solved
Bypassing game protection — analyzed anti-cheat mechanisms, found ways to bypass them

Reverse engineering — used DNSpy to analyze the game code and find the necessary methods

Method interception — applied Harmony to modify game behavior in real-time

Performance optimization — ESP functions work without significant FPS drops

Compatibility — ensured operation with the latest version of the game (v1.7.0.2-PS)

Skills I Acquired/Reinforced
Working with Unity and MelonLoader

Reverse Engineering and memory analysis

Understanding the principles of game anti-cheats

Creating custom UIs in Unity

Writing clean, structured code in C#

Working with the Harmony library for method interception.
