Hot Wheels Unleashed 2: Mega Bites Free Pack

Summary pulled directly from Steam - Some text may only be applicable to Steam platform

It's called Mega Bites, but this pack has nothing to do with computers.
This is something way more intense! We are talking about two Hot Wheels™ Originals famous for their contagious “smile”. The first is Hotweiler™, an untameable purebred with ruthless strength: when it aims for the finish line, not even its chain can stop it! With such a pedigree, victory is always within reach. And then the legendary Shark Bite™, the shark that will give you a sea of satisfaction. When the opponents see its fin in the mirrors for them it’s already too late: Shark Bite™ will devour them in one bite.
Add them to your collection now. Missing Mega Bites Free Pack would be a big mistake!

This DLC includes:

Hotweiler™
Shark Bite™
