The opportunity

Elex’s Clash of Kings (@ClashofKingsCoK), a multiplayer real-time strategy game, enjoys a huge worldwide audience. The company is always looking for new ways to expand its audience around the globe. In order to boost brand awareness in the UK, the company brought Clash of Kings to life by devising a real-life battle in London. To merge the physical and digital experience, the brand captured the live event on Periscope and amplified the experience to the Twitter audience.

The strategy

Elex brought Clash of Kings to life by staging a mock battle at London’s Tower Bridge where an army of Knights descended on Potter’s Field to fend off giant 10-foot-tall Lava monsters. The brand used a variety of Twitter solutions to promote the event and amplify the live event experience on Twitter.  It ran teaser videos using Promoted Video to generate pre-event buzz and a Promoted Trend to promote the event hashtag, #LondonsBattle, to bring people’s attention to the event. The battle was broadcast live on Periscope for the Twitter audience, fans, and new players alike to experience the #LondonsBattle event as it happened.
