Based on the link here:
It seems that only this person participated:
1. Memphiz Zx
Memphiz Zx gets a copy as there are more than one copies remaining.
The remaining copies will be given to those who wants it.
Please message Deimos on facebook if you want a copy of Dota 2.
This Dota 2 giveaway is a failure though.
Thank you for your time.
