To keep warm this winter, it may be wise to engage in a high-energy activity.

Sprinting is a good one. Luckily, it's that, and much more, that Sega is serving up with its iOS winter release lineup.

Sonic The Hedgehog 2 Remastered

Heading the release lineup is a remastered version of Sonic The Hedgehog 2, which we marked down for its performance and control issues previously.

As was the case with the remastered version of Sonic The Hedgehog on iOS, Sega seem to be addressing the problems we previously brought up. So expect enhancements to performance and touch controls at the very least.

Sonic The Hedgehog 2 Remastered will see the sequel debut for Android, and will be available for owners of the original version on iOS as a free upgrade. Not long to wait, either, as November 2013 is the release window.

Sega All-Stars Racing: Transformed

Sonic & Sega All Stars Racing: Transformed

Next up is Sonic & Sega All-Stars Racing: Transformed, which is the follow-up to the Platinum Award-winning Sonic & Sega All-Stars Racing. The main addition with this sequel, as indicated by the title, is that cars transform into boats and planes.

Transformed will be a lighter version of the console version of the racing game as with its predecessor.

However, a new World Tour mode designed specifically for the mobile version of Transformed, allows for local and online multiplayer races for up to four players.

Sega All-Stars Racing: Transformed is slated to launch for Android and iOS in December 2013.

Rhythm Thief & the Paris Caper

Rhythm Thief

We already knew that Sega intended to bring the 3DS game, Rhythm Thief, over to iOS as a freemium title.

The main bit of information here include a title change from Rhythm Thief and the Emperor's Treasure to Rhythm Thief & the Paris Caper. This suggests that this is an entirely new title, rather than being a port of the 3DS version.

The other tid-bit is that we're told not to expect the Paris Caper on the App Store until early 2014.

As with the previous game in the series, Rhythm Thief on iOS will involve matching beats in mini-games to gather clues and sneak past enemies in order to pursue an investigation into your father's death.

Demon Tribe

Demon TribeLast, but not least, is Demon Tribe.

This comes from Masayoshi Kikuchi, who previously worked on the Panzer Dragoon games, and is therefore practicd with dark fantasy worlds.

Expect Demon Tribe to blend MOBA, card collecting, and action-RPG gameplay on iPad, iPhone, and iPod Touch.

Demon Tribe involves building up a team of fighters, and fusing their powers with captured demons.

With "Demon Summoning" abilities, you can also turn your team into demons, too. Nifty.

Both single player and online multiplayer modes are provided, with the latter supporting up to six players, with co-op mode, and a competitive, synchronous 3v3 team battles.

Demon Tribe's expected release date for iOS is also left at "Early 2014".
