Sonic After the Sequel is a 2013 platform video game created by Brazilian student Felipe Daneluz (LakeFeperd). It is an unofficial game based on the Sonic the Hedgehog series and set between the official games Sonic the Hedgehog 2 and Sonic the Hedgehog 3. Daneluz's second Sonic game, it follows Sonic Before the Sequel, which is set between the original Sonic the Hedgehog and Sonic the Hedgehog 2. Like its predecessor, After the Sequel stars Sonic the Hedgehog and his sidekick Tails in a quest to retrieve the Chaos Emeralds from Doctor Eggman.
After the Sequel was inspired by Sonic Heroes and other games both inside and outside the Sonic series, and it was developed with Sonic Worlds, an engine based in Multimedia Fusion 2 that reduces the amount of computer programming involved in game creation. It was released as a free download for Windows personal computers on June 15, 2013. The game was very well received by video game journalists, who lauded its preservation of retro Sonic gameplay and its 1990s-style soundtrack. The trilogy of Before the Sequel, After the Sequel, and their successor Sonic Chrono Adventure performed unusually well for fangames, having been downloaded 120,000 times by March 2014.
