Guilty Gear XX (ギルティギア イグゼクス Giruti Gia Iguzekusu?), also known as Guilty Gear X2 and subtitled The Midnight Carnival, is the third full installment in the Guilty Gear series of fighting games. First released in 2002, it has since received five updated versions. GGXX furthered the plot of the series and introduced new characters and gameplay mechanics. The graphics also appeared to be notably improved. It was much more commercially successful than its predecessor Guilty Gear X.[cit
