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

  1. Clone the repository:
git clone https://github.com/memphis9339/standoff2-crystal-server.git
cd standoff2-crystal-server
  1. Install dependencies:
shards install
  1. Compile Protocol Buffer definitions (or use pre-built in "protos" folder):
cd bin
protoc -I ../protos --crystal_out . ../protos/*.proto
  1. 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.
