Sonic Adventure 2 speeds on to Steam

The Dreamcast original Sonic Adventure 2 is now available on Steam for PC.

It costs $9.99, and the add-on Battle is available for $2.99. The extra content includes six new characters, 21 two-player battle maps, and Chao Karate from the GameCube's Sonic Adventure 2: Battle.

Sonic Adventure 2's arrival on Steam may lead to Nights HD as well — a fellow member of the Sonic Heritage Collection (which also includes Jet Set Radio) that was confirmed for PC in summer. Both games came to the PlayStation Network and Xbox Live Arcade last month.
