Surprise launch at Demo 2012 - So what is Cachetown?
CacheTown in its most basic form is an event based scavenger hunt that utilizes location based augmented reality to put you and your surroundings at the heart of the action. In order to win prizes such as tickets to movie premiers, new phones, guitars, backstage concert passes or cold hard cash gamers are charged with one mission – to play. Yep, that’s your mission and that’s what we mean when we say “play and win.” You’d probably think that that’s the best part… but it’s not. The best part is that all of the above is absolutely free – all because we feel that as a gamer your job is to play… not to pay.
