Real racing 2 on rMBP 13?

Hi everyone,
I am typing on my new rMBP 13, and I love it :)
Anyway I found an app that looks pretty cool (real racing 2), and it says it needs and Nvidia or ATI video card with 128 mb of memory. It also says that Intel GMA series graphics cards are not supported. That means that intel 4000 graphics on rmbp 13 is not supported, right?

So does it not work on rmbp 13 inch, did anyone try to download it yet? What happens if I try to download it?

Thanks
