The Sonic Stadium has discovered even more Sonic Boom concept art, but this time for last year’s Nintendo 3DS release Sonic Boom: Fire & Ice. The images were found on the portfolio of Casey Holtz a contract designer who worked on the game’s level and system design.
Level layout on 12 Race levels
Level layout on4 Adventure levels
Boss battle design, tuning, scripting
General systems tuning and support.
The concept art gives us a look at early stage and boss level sketches. In the original image files we can see they date back between November 2014 and early 2015 telling us the game was still in the very early stages not long before it was announced in June 2015, so it’s no wonder the game was delayed until September last year.
Check out the images in our gallery below and share your thoughts in the comments.
