standoff2-crystal-server
The world first open-source Standoff 2 server written in Crystal with Protobuf
"Language for humans and computers"
About
This project is a reverse-engineered implementation of the Standoff 2 game server, built from scratch using the Crystal programming language and Protocol Buffers for efficient network communication. It aims to provide an open-source alternative for understanding and hosting private Standoff 2 game servers.

Features
- High Performance: Built with Crystal for speed and efficiency
- Protocol Buffers (protobuf.cr): Fast and compact binary serialization
- Open Source: Fully transparent codebase
Requirements
- Crystal 1.x or higher
- Protocol Buffer compiler (protoc)
- Brain
Installation
- Clone the repository:
git clone https://github.com/memphis9339/standoff2-crystal-server.git
cd standoff2-crystal-server
- Install dependencies:
shards install
- Compile Protocol Buffer definitions (or use pre-built in "protos" folder):
cd bin
protoc -I ../protos --crystal_out . ../protos/*.proto
- Run the server!
crystal run main.cr
Notes
- The server has no Database and server side logic. You need to implement it by yourself (currently only stub methods are implemented)
- In the game client you need to hook ClientService.Connect(string host, int port) and replace the host string to your.
- Tested on original 0.12.0 game build.
