Sonic, Sega’s iconic blue hedgehog, is celebrating his 20th anniversary today.

To commemorate his second decade, Sega is hyping its next Sonic game — Sonic Generations — and releasing a 20th anniversary bundle on the PlayStation store at a price of $19.99 for 20 days.

The U.S. PlayStation Blog didn’t detail what’s in the bundle, but the UK’s PSN blog said that the bundle will include: Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 4: Episode 1, Sonic Adventure and the Sonic the Hedgehog dynamic theme.

The new game will hit stores in November, for the 3DS, XBox 360 and PlayStation 3. Gamers will get to play as the 1991-era Sonic and the modern-day version of the character. The game has levels with both a classic side-scrolling environments and more modern designs.
