If you are a Sky VIP member, be sure to check out the Sky VIP App on your phone.
I went on it this morning and under "exclusive content for you" I found this deal. This is because Sky are official partners with this years Call of Duty title - Cold War.
Upon clicking this deal, you will be given an exclusive redemption code that needs to be input on callofduty.com/redeem
An Activision account is needed to sign in and you have to already own a copy of Black Ops - Cold War. I am not sure if this offer work retroactively (you might be able to redeem the offer even if you do not yet own a copy of this game)
The app will provide you with a full list of instructions in order to obtain the SkyVIP Exclusive operator skin for Beck.
For the sake of transparency, I am Platinum VIP member (been with them for over 10 years), but I am sure this offer is available to all VIP members, although I am not able to verify this. If anyone can comment below to let others know that would be fantastic.
