Glu Mobile bought Gamespy Technologies (the entity responsible for GameSpy multiplayer services) from IGN Entertainment in August 2012,[8] and proceeded in December to raise integration costs and shut down servers for many older games, including the Star Wars: Battlefront series, Sniper Elite, Microsoft Flight Simulator X and Neverwinter Nights, with no warning to developers or consumers.[9] GameSpy Technologies remained operational and did not make any announcements of an impending shutdown; the two GameSpy companies were separate entities and only related by name.[10] Glu also shut down online multiplayer servers for several titles on the Nintendo DS and Wii, such as Mario Kart DS, Super Smash Bros Brawl, and Mario Kart Wii. Glu shut down the rest of Gamespy effective on May 31, 2014.[11]
