Build Status Discord GPL DonateBTC

GPL v3


  • Replicate of the great game Ace of Spades (classic voxlap)
  • runs on very old systems back to OpenGL 1.1 (OpenGL ES support too)
  • shares similar if not even better performance to voxlap
  • can run on "embedded" systems like a Steam Link

Why should I use this instead of ...?

  • free of any Jagex code, they can't shut it down
  • open for future expansion
  • easy to use
  • no hidden bugs

Quick usage guide

As of right now, you can download the newest stable version from the releases page.

You can get nightly builds here.

You can either:

  • use the client temporarily by extracting the downloaded zip into a new directory.
  • extract all contents to your current Ace of Spades installation directory (normally found at C:/Ace of Spades/), effectively replacing the old voxlap version

Build requirements

This project uses the following libraries and files:

Name License Usage GitHub
GLFW3 ZLib OpenGL context Link
OpenAL soft LGPL-2.1 3D sound environment Link
inih BSD-3.Clause .INI file parser Link
stb_truetype Public domain TrueType font renderer Link
dr_wav Public domain wav support Link
http Public domain http client library Link
LodePNG MIT png support Link
libdeflate MIT decompression of maps Link
enet MIT networking library Link
parson MIT JSON parser Link
log.c MIT logger Link
GLEW MIT OpenGL extensions Link
hashtable MIT hashtable Link
libvxl MIT access VXL format Link
microui MIT user interface Link

You will need to compile the following by yourself, or get hold of precompiled binaries:

  • GLFW3
  • GLEW
  • OpenAL soft (only needed on Windows)
  • libdeflate
  • enet

Follow the instructions on their project page, then place produced static libraries in deps/.

All other requirements of the above list (like single file libs) will be downloaded by CMake automatically and don't need to be taken care of. Because state of copyright of 0.75 assets is unknown, CMake will also download additional assets from here which are not part of this repository.


This project uses CMake to generate all Makefiles automatically. It's best to use MinGW-w64 for GCC on Windows. You can generate the required files by opening cmd.exe in the build/ directory and typing:

cmake -G "MinGW Makefiles" ..

If everything went well, the client should be in the build/BetterSpades/ subfolder.

When starting client.exe, you will be greeted by a server list. Select a server on it to start playing! You can also start the client the same way as you did with the voxlap version by opening cmd and putting an aos:// link in as the first argument:

client.exe -aos://16777343:32887 //Connects to a local server


Compilation now works the same on Linux. Just change the build system to Unix Makefiles or leaving it as default will work too (cmake ..).

You can build each library yourself, or install them with your distro's package manager:

sudo apt install libgl1-mesa libgl1-mesa-dev libopenal1 libopenal-dev libglfw-dev libenet-dev libglew-dev

(this does not include libdeflate which is a requirement too, see Wiki/Building for more details)

Start the client e.g. with the following inside the build/bin/ directory:


Or connect directly to localhost:

./client -aos://16777343:32887


The same instructions for Linux work on macOS aside from some minor differences. First, use Homebrew or MacPorts to grab dependencies:

brew install glfw enet

The development headers for OpenAL and OpenGL don't have to be installed since they come with macOS by default. libdeflate should be installed and placed manually in a way similar to Linux. See Wiki/Building for more details.
