Flash forward to 2019, and it looks like all three games (or mods, to be exact) have now been officially released by cereal manufacturers General Mills, citing the third fan-made chapter as officially canon.
A fan-made third installation was created solely by Charles Jacobi – Art Director and Lead Artist of the former development team – and released in 2008. It was so popular (under 6 million CDs were put out!), it even got itself a sequel a year later. Instead of making some generic, butt-ugly edutainment title, they decided to take the DOOM engine and repackage it into a kid-friendly first-person shooter. Some clever clogs at Digital Cafe were contracted to create a video game to be packaged within boxes of Chex in 1996.
