Yep, you guys read that correctly. Beasts of War is giving away a Reaver Titan, Warhound Titan, and a pair of Stompas (given together) as part of a promotional campaign.
The deal is that they have an account on Youtube, Twitter, and Facebook. The first Beasts of War account to earn 40,000 (fitting) subscribers/follows/likes then has one member of said subscriber/follow/like list chosen at random to receive the Reaver Titan, Chaos available on request. The second Beasts of War account to reach the same milestone goes through the same process but with the prize being a Warhound Titan, again Chaos is available on request. The last of the three Beasts of War accounts to reach 40,000 people does the random draw again and the winner receives a pair of Stompas; one new in box and the other painted by
BoW John.
