To demonstrate the burden of a large mortgage, we created a game where users could defend their homes and shrink their mortgages. After choosing a house they had to shoot at mortgages that fell out of the sky in the style of "Space Invaders". In the end they could send the game and their scores to friends, and shrink their mortgages for real on the One Account site. Breaking away from traditional financial services activities on the web whilst still being highly relevant to the product, it immerses the consumer in the brand in a fun, non-intrusive fashion.
