Sega are getting quick to the draw with the rereleases of their more iconic games of their past as Sonic Adventure 2 and  Nights Into Dreams have landed on the Xbox Live Arcade and PSN today brining the HD visual upgrade and trophy/achievement support like Jet Set Radio HD did a few weeks ago.

This version of Sonic Adventure 2 retains everything about the original Dreamcast release leaving players to purchase the “Battle” DLC to transform the game into it’s more complete Gamecube version which launched a few years later. The ‘Battle Mode’ pack includes multiplayer modes and additional challenges for your raised Chao like ‘Chao Karate’.

Nights Into Dreams will also include ‘Christmas Nights’, a holiday-themed expansion that was previously only included in a SEGA Saturn holiday bundle in 1996 or through special promotions.

Both titles are available for $9.99 each from today with ‘Battle Mode’ DLC pricing to be confirmed.
