Sega Ages Sonic the Hedgehog and Sega Ages Thunder Force IV will launch for Switch via the Nintendo eShop in August for 925 yen each, Sega announced.

Here is an overview of each game’s features, via their official websites:

Sega Ages Sonic the Hedgehog (Official Website) Original Mode: Enjoy the original Sega Genesis / Mega Drive version of Sonic the Hedgehog. Stage selection, which was a cheat code in the original version, can be turned on / off at startup. Additionally, the “Spin Dash” action added in Sonic the Hedgehog 2 and “Drop Dash” action aided in Sonic Mania have also been added (which can be disabled in the game options). Also, in addition to the standard Japanese and overseas game versions, you can also choose to play the Mega Play version. Mega Play was a Sega Genesis / Mega Drive formatted for arcades to play popular Sega Genesis / Mega Drive games. The Mega Play version is a time attack game where the goal is to clear familiar stages within the time limit, allowing players to enjoy a condensed form of Sonic the Hedgehog‘s thrill and sense of speed through stages configured to emphasize speed.

Ring Keep Mode: A support mode added in 3D Sonic the Hedgehog 2 for 3DS. Since the player will always start the stage with 10 rings, it is easy to come back from boss battles or mistakes made right after the stage begins.
