Some while back I was asked to help a game dev team re invent and expand an old classic arcade shooter as the Art Director of that project. Since I love that genre and retro art style I was delighted to help out with just that. I also had been looking for a project that could benefit from voxel art, as I've seen some really beautiful work made with that. This seemed like a perfect match. The idea was to keep the style of the original game but also evolve that and the mechanics to cater for both a new audience and fans of the original title. Below is the process of that exploration going from the pixelated 2d art to a voxel based 3d world.

Note: I don't claim ownership of the original art below, I am showing it for reference only.
The voxel art was not made by me directly, I lead the vision and art direction of this.

Final key art below. See the process further down.
