Holman (programmer). Former Digital Café sound design leader Andrew Benson also contributed several songs for the game. Originally intended as a single standalone level, Jacobi announced the development of a full sequel at the Chex Quest Fan Page (Chexquest.org) in June 2008, and the full game was released in September of the same year. Chex Quest 3 employs the ZDoom source port (version 2.3.1), and is considerably larger in size than the previous two games. Jacobi's release of Chex Quest 3 also included ZDoom-based versions of Chex Quest and Chex Quest 2, with significant enhancements and noted problems redressed. Chex Quest 2 in particular had been remastered, with some levels significantly revised or completely overhauled. Charles Jacobi credited the praise and compliments of fans, especially through fan-made projects such as one titled "The Ultimate Chex Quest", as inspiration to complete this project. If anyone wishes to play Chex Quest 3 in latest versions of ZDoom and GZDoom, then download Chex Quest 3 (version 1.4, dated 24 June 2009) and extract its contents, download the latest version of the desired port, then copy the chex3.wad file into the ZDoom or GZDoom folder. The plot for this sequel is set ten years later than the events of the first two Chex Quest games, with the invasion of the planet Ralston by the Flemoids. The breadth of the story was expanded to a much larger scale, possessing a seemingly more grim scenario than the predecessors—the latter of which Charles Jacobi dispelled as unintentional, in that he simply "wanted it to feel bigger" than the first two games. Chex Quest HD In response to an interview question regarding the possibility of a canonical Kickstarter-funded Chex Quest 4, Jacobi pointed out that the franchise is owned by General Mills so a funded project would likely violate copyright and trademark laws. However, freely distributed non-tarnishing modifications created by hobbyists would probably be protected as free speech. In 2016, Jacobi revealed that a high definition remake of the original game called Chex Quest HD was in development using Unreal Engine 4 with the permission of General Mills. A trailer for the remake was released in February 2019. Like the original game it will contain five levels and be released for free. The Chex Warrior, the protagonist of the original game, is given the name Fred Chexter in the remake. The remake was released on May 18, 2020,
