Guilty Gear Xrd -SIGN- is a 2.5D fighting game developed by Arc System Works and released by Sega for arcades (using their PC-based Sega RingEdge 2 hardware) exclusively in Japan on February 20, 2014.
The fourth main installment of the Guilty Gear series (after the Λ Core Plus revision of Guilty Gear XX), Xrd features a new game engine built on Unreal Engine 3. All characters and environments are now rendered in cel-shaded 3D, using special rendering techniques for the characters (such as deliberately cutting frames of animation and limiting background lighting) to give the illusion of 2D hand-drawn character art.
The game's story takes place in the year 2187, shortly after the events of Guilty Gear 2: Overture and seven years after the events of the original Guilty Gear. A mysterious young woman identifying herself as "Ramlethal Valentine" has declared war on the entire world.
The game was later released on both the PlayStation 4 and PlayStation 3 in Japan (self-published on December 4, 2014), North America (published by Aksys on December 16, 2014), and Europe (published digitally by SCEE on June 3, 2015). It was later digitally released (self-published via Steam) for the PC on December 9, 2015.
The game later received two major updates: Guilty Gear Xrd -Revelator- in 2015 and Guilty Gear Xrd REV 2 in 2017. Both versions added new characters while revamping both UI graphics and game balance.
The original arcade release included 13 playable characters (one of whom is new) and one unplayable boss (who was made playable shortly after).
The Console versions of the game added three new playable characters as paid DLC (although one of them can be unlocked in-game), for a total of 17 playable characters. All three added characters were later added back into the Arcade version.
- Ramlethal - She is the game's final boss and was made playable on April 8, 2014.
- Elphelt - Added in Console versions as paid DLC on December 16, 2014. Added in the Arcade version on March 19, 2015.
- Leo Whitefang - Added in Console versions as paid DLC on December 23, 2014. Added in the Arcade version on March 19, 2015.
