​Clark, the quark who reveals the truth about the Particle World. A hidden yet fragile truth that was placed in order to maintain the lie of a dwarf star, the famous Great Mother, who used particles as her slaves for her own purposes.

After revealing against the law, Clark immersed himself into a search for answers, with one of her friends, Emma, a search that led him into the path of becoming a hero: the warrior everybody was waiting, the hero who brought truth with the chaos and union with words, and the one who broke the chains of slavery with fierce and anger when all the particles joined to him and created the war that transformed Phantom City, the place where they used to live, in a epic battleground with particles thirsty for justice fighting like an army with The Great Mother and its soldiers.

  • The objective of Nuclear Reaction is to take control of the board by eliminating your opponents' atoms.

  • Players take it in turns to place their atoms in a cell. Once a cell has reached critical mass the atoms explode into the surrounding cells adding extra atoms and claiming the cell for the player.

  • A player may only place their atoms in a blank cell or a cell that contains atoms of their own color. As soon as a player loses all their atoms they are out of the game.
