Two things we love – Good games and good campaigns (not to mention good consumer engagement).

We also love to point out people and companies that are doing cool things in mobile and social media – and of course it’s even better when one of those innovative companies is a Waterfall Mobile client.

Video game publisher and developer Ubisoft came up with an innovative digital campaign around Tom Clancy’s Splinter Cell Conviction.  It’s one of the first interactive campaigns to use mobile as a means of giving away free in-game content to players.  Since that exclusive content is just a text away, this is a great way to engage with consumers and build a mobile subscriber list.

When gamers text WEAPON to 44144*, they receive a text back with a code to unlock a secret weapon in the game.  We won’t tell you what it is – you have to text in to get it – but you won’t want to miss it.

Ubisoft let its gamer community know about the game code by pushing out messaging to its email list, mobile subscribers, Facebook, and Twitter.

On the first day of the program, the company nearly doubled its mobile subscriber list.   Within the next few days the list more than tripled in subscriber numbers. The campaign was so successful that Ubisoft has decided to allow more people than originally planned to get codes to unlock the content.

This is another testament to what compelling messaging and offerings can do in terms of user engagement. Ubisoft gave gamers what they wanted, and the gamers responded.

Way to engage your community!

The result thus far have been amazing – so amazing that the company is already planning content that can be unlocked via text for future games. Next up: Prince of Persia.
