Empty Game CD. [SOLVED]

I bought a new game 'Prototype 2' turned out to be a blank disc. Even observed the multicolour side of it to see if it was empty or full. But to my horror it was full.
Why does this happens???

Hello,

First thing to do: go back to the store where you got it from.
Since you're from New Delhi, are you sure it's an original disc? If it's a pirated disc, there's a chance they forgot to burn it or they included the wrong disc.

turns out to be a pirated one
downloaded a torrent instead
Thnks!!

Hello there,

Good, enjoy your game!
