I heard you can get a partnership with alienware or something like that. Not even sure if the public can do that. Not even sure what it is.

No unchained Alistar is a free champion skin If you subscribe to him on facebook

It's not facebook, its Riot's Youtube channel. Here's a link:

Riot does several promotional campaigns where the reward is a skin that will also unlock the champion if you do not already own them. Riot Girl Tristana, Nightmare Cho'Gath, and Unchained Alistar have all been rewards of various promotional spots. They also give away skins for attending different gaming conventions alongside of the Riot team. In general it is just a good idea to keep your eye out for announcements here in the forums that will alert you to any upcoming giveaways. The Riot staff is very good about keeping the community informed.
