See the article Net Slum for information on the original Net Slum.
Net Slum Tartarga is a version of Net Slum featured in the .hack//G.U. Games. It appears much like the Net Slum from the original .hack//Games, but it rests upon the back of Tartarga, who is now a giant turtle, much like his counterpart in the Epitaph of the Twilight. Net Slum Tartarga is overseen by Zelkova, who refers to it as something like his hometown. It also features a Chaos Gate from which all the areas of The World R:2 can be accessed. This feature requires the player to switch servers from within the Chaos Gate's menus. There is a time delay whilest doing so, implying that Tartarga must physically move to that server's location.
After Corbenik's explosion damages Haseo's PC, Tartarga flies overhead to rescue his dying PC body. Here, Haseo becomes one with his Epitaph to unlock his Xth Form. Later, when the Root Towns threaten to collapse under the power of Cubia, Yata moves the Serpent of Lore to the Bridge of Net Slum Tartarga and Zelkova moves Canard's @home to the Net Slum Tartarga. Shop Acorn still manages to sell items.
