 The remaster offers several improvements over the original Perfect Dark that was released for the Nintendo 64 in 2000 . The most remarkable change is that any of the multiplayer modes , including co @-@ operative and counter @-@ operative , can now be played in either <unk> or through the Xbox Live online service . Combat <unk> matches are still capped at 12 entities , but the game can now comprise eight players online simultaneously , an improvement to the original 's cap of four players and eight Simulants . Players can also play against more than eight Simulants as long as there are enough slots available in a match ; for example , a single player can play against 11 Simulants ; such a feature was not possible in the original game . Unlike the original game , all the multiplayer content is unlocked from the beginning , and weapons from the game 's predecessor , which were originally only available in the missions , are now available to use in multiplayer . The game features an online <unk> system and players can earn achievements and in @-@ game crowns by <unk> certain tasks . The game also includes two new control set @-@ ups , entitled " <unk> " and " Duty <unk> " , which are based on the popular first @-@ person shooter franchises Halo and Call of Duty respectively .
