Dark Synchro Summon is the antithesis of a Synchro Summon. Instead of the levels of the Tuner Monster and the non-Tuner monster(s) adding up to the selected Synchro Monster's Level, the Dark Tuner Monster's level is subtracted from the level of a non-Tuner monster(s), thus making a Dark Synchro Monster. Dark Synchro Monsters are new and unique to the game as they are the only monsters with a Negative Level. This feature is only available in the anime and the video game, Yu-Gi-Oh! 5D's Tag Force 4.
