a time-trial mode and a two-player versus fight mode. Like the arcade version, each turtle was given unique attributes in areas such as speed and strength. In addition, the move to throw enemies off-screen can now be performed intentionally (instead of just randomly), a technique specifically required at the end of the Technodrome level. Emulated re-releases An emulated conversion of the original arcade game can be unlocked after completing the first batch of missions in Teenage Mutant Ninja Turtles 3: Mutant Nightmare. The game is emulated from the four-player version. Differences include the lack of a score counter, an entirely new soundtrack (likely due to rights issues with the original soundtrack), altered voices, and a slightly choppy frame rate compared to the arcade. Much like the version it was based on, the characters are assigned by controller. This means that Donatello and Raphael are not playable in the PlayStation 2 version without a multitap, as the base console only has two controller slots. The new soundtrack is a re-arranged version from the Nintendo DS version of Mutant Nightmare. The arcade and SNES versions of the game were re-released as part of Teenage Mutant Ninja Turtles: The Cowabunga Collection in 2022. Reception Following its release, Turtles in Time became Konami's best-selling arcade title. In the United States, the home console conversion was the top-selling Super NES game in September 1992. Reviews The arcade game received positive reviews. Although critics found that the second game was largely similar to the previous arcade game, they felt that it was a net improvement over its predecessor on all points, including graphics, music and gameplay. Overall, the game was hailed for staying true to its source material. The SNES version was praised for its additional stages and gameplay modes. The four reviewers of Electronic Gaming Monthly gave it unanimous scores of 9 out of 10 each, applauding the fun gameplay, the new moves, the accurate recreation of the arcade version's graphics, and the two-player versus mode, though they criticized that the game is too easy. The SNES game was lauded in Allgame for its visuals, which replicate the cartoon's art style. The game's music and sound effects have also been praised. However, the game was criticized by The Armchair Empire for its repetitive gameplay and short length. Nintendojo called Teenage Mutant Ninja Turtles IV: Turtles in Time the best Ninja Turtles game of all time.
