Silver Days: Battle Evolution+

Silver Days: Battle Evolution+ (銀デイズ：バトルエボリューション), also known as Duel Evolution+ (デュエルエボリューション), is a fighting game based on the Silver Days series, developed and published by Alex Guy's own studio, SEVENS. It is an updated and enhanced version of Battle Fusion, released on PC and for mobile devices on June 7, 2015.

Like the original game, Battle Evolution+ includes major characters from the first five story arcs of the series, however, it also adds characters from Game of Darkness, eventually including characters from Silver NX. Commemorating the anime, Battle Evolution+ features an expanded story mode, loosely representing the events that transpired in the first five arcs of the original series, in Game of Darkness, and in the first few arcs of Silver NX.
