My project file (.blend) is now available on Github, feel free to download it and have a look around.
You’ll need to have git-lfs (Large File Support) installed because it’s bigger than the standard 50mb threshold, and will only get bigger!
Once you’ve installed it, you’ll be able to run from your command shell:
git clone https://github.com/davethefan/sheffield-fps.git to download the file, you’ll be able to open it in Blender as normal.
Alternatively, you can download the project as a zip file from the link above, or direct download from this website
You’ll need to have the Armory engine installed if you want to try and compile the game (which isn’t currently working) – but it’s not required if you just want to have a look around and render scenes and see how the file is organised.
