Take-Two Inter­ac­tive has filed a law­suit against the cre­ators of a reverse-engi­neer­ing open-source soft­ware called Re3, which allows GTA III to run on the Nin­ten­do Switch and PlaySta­tion Vita. The law­suit was filed on Sep­tem­ber 2nd in the Unit­ed States Dis­trict Court in Cal­i­for­nia and states that Re3 is act­ing unlaw­ful­ly by copy­ing, adapt­ing, and dis­trib­ut­ing the source code to GTA III and GTA: Vice City.

Take-Two’s lawyers said the Re3 tech­nol­o­gy allows any­one to play these titles on plat­forms the games weren’t meant to be released on, includ­ing the Switch and the Vita.

Defen­dants’ con­duct is know­ing, will­ful, and delib­er­ate. Defen­dants are well aware that they do not pos­sess the right to copy, adapt, or dis­trib­ute deriv­a­tive GTA source code, or the audio­vi­su­al ele­ments of the Games, and that doing so con­sti­tutes copy­right infringe­ment,” the lawyers stated.

The suit specif­i­cal­ly calls on Re3 devel­op­er Ange­lo Papen­hoff. He report­ed­ly stat­ed in pub­lic he was “very much wor­ried” about Take-Two find­ing out about Re3.

The law­suit comes after Take-Two attempt­ed to remove the source code from the inter­net ear­li­er this year. In response to this, the com­pa­ny’s lawyers say the defen­dants know­ing­ly filed bad faith counter-noti­fi­ca­tions that mate­ri­al­ly mis­rep­re­sent­ed the legal­i­ty of their con­tent, appar­ent­ly claim­ing that because they alleged­ly ‘reverse-engi­neered’ the games’ source code, they some­how can­not be liable for copy­right infringement.”

Yet while mak­ing this claim, Defen­dants also have bragged that their deriv­a­tive ver­sions of the Games are func­tion­al­ly and visu­al­ly iden­ti­cal to the orig­i­nals, and have even sug­gest­ed they be used for unau­tho­rized ‘mod­ding pur­pos­es,’ ” the suit says. “As such, defen­dants’ soft­ware plain­ly infringes Take-Two’s exclu­sive rights to copy, adapt, and dis­trib­ute the games.”

Take-Two says the actions of the defen­dants con­tin­ues to cause “irrepara­ble harm” to the com­pa­ny. The Re3 soft­ware not only allows GTA III and Vice City to be playable for any­one on new plat­forms, but it also gives “count­less oth­ers [the abil­i­ty to] cre­ate their own unau­tho­rized deriv­a­tive ver­sions of the games.”

Take-Two is seek­ing dam­ages, as well as an injunc­tive and oth­er “equi­table” relief.

This legal action comes amid reports that Take-Two is get­ting ready to announce remas­ters for GTA II, Vice City, and San Andreas. GTA III will be cel­e­brat­ing its 20th anniver­sary this year, and Rock­star has already told fans to look out for some “sur­pris­es.”

Even if these games don’t end up get­ting remas­ters, 2021 will still see the release of Grand Theft Auto V for PS5 and Xbox Series X|S in Novem­ber. A stand­alone edi­tion of GTA Online will also be launch­ing this year. 

GTA 6 is also report­ed to be in works, but won’t be hit­ting the mar­ket until 2025.
