Sword Art Online Variant Showdown is a new mobile game developed by Bandai Namco Entertainment Inc. that celebrates the 10th anniversary of the SAO anime. In this game, players take control of anime characters like Kirito and Asuna in 3D battles against fearsome bosses like The Gleam Eyes. The game uses a unique SAO battle system that allows players to use character-specific Sword Skills and switch between offense and defense on the fly. Players can also counter enemies' special attacks with parries and awaken their characters to unleash their true power on the battlefield.

The game features an all-new original storyline that takes place in the world of Cross Edge, a VR action game developed by a middle school genius. Players can choose three characters they know and love from SAO and take control of them in battle. Each character has their own special techniques and skills, so players must form parties that exploit their opponents' weaknesses. The game also allows players to equip their characters with ability cards to raise their power and customize characters to their liking by changing the color of their outfits or equipping different accessories.
