The objective of the game is to take control of more sub-nuclear matter than your opponent. Clicking on a block within the playing field allows you to gain control by inserting a single sub-nuclear particle within it, if the number of particles within a block becomes too great, the block becomes unstable, and a nuclear reaction will occur if any more particles are inserted. The player who causes the nuclear reaction then gains control of the blocks surrounding the initially unstable block. Corner blocks become unstable when they contain 3 particles, bordering blocks become unstable when they contain 5 particles, and the remaining blocks within the playing field become unstable when they contain 8 particles. Depending on their position, nuclear reactions do not always work to your advantage, they can also make your opponent win the game.

Nuclear Fission was developed with Fenix for the GP32 by PauTo, it is an attempted remake of QuaRkZ, a game developed with Flash by Manuel Fallmann, and originally featured on Nuclear Fission is intended to be a 2 player game (sharing the same controller), but the game can be played by a single player.

This release comprises of Nuclear Fission along with DCEvolution's version of Chui's Fenix SDL Loader (FSL) from November 2004, edited to exclude the Fenix splash screen and jingle, so the game loads directly.

The menu options have been removed (containing a help page which required a reboot after viewing), the menu graphic has been edited, and the remaining text within the game has been translated to English. The controls for the game have been reconfigured to enable all game options, to be user friendly with the Dreamcast controller, to avoid inadvertently resetting the Dreamcast during play, and the game no longer requires a reboot after one play. Due to the alterations for this release, a download for the original GP32 version has been made available.
