Sonic the Hedgehog 4 Episode: II

[NICKtendo DS]

Whatsup with Episode Metal? Is it a DLC?

And I find that Sonic moves very smooth in Ep2 but his homing attack is a little bit overpowered. Like if you jumpdash, you'll get tons of speed.
Yes, I downloaded Beta 8

I believe it's DLC for Episode 2 you get when for free when you own both Ep. 1 and 2.
