To celebrate and promote the much-anticipated release of METAL GEAR SOLID V: THE PHANTOM PAIN, Konami partnered with Razer and others for the "Pax Prime Tradshow Sweepstakes".  Entrants simply had to "like" Razer on Facebook and enter their details for a chance to win a grand prize that included a new computer and keyboard from Razer as well as a copy of the game and a yearlong subscription to Crunchyroll, a streaming service dedicated to Anime. 

The sweepstakes was promoted on social media as well as in a dedicated section of the Razer website.
