Today Coca-Cola launched a Tron: Legacy app for iPhone, iPad, and iPod touch owners. But nevermind the Coke Zero sponsership; this game appears to look awesome in theory. It’s being touted as the “first location-based video game” and the objective is simple: Build a Light Wall as you move about the real world and earn points by forcing other players to crash into it. The app uses the iPhone’s GPS to track your location and show you on a Grid-themed map where other players are located. Coke promises to push out updates to the app surrounding the release of the film it’s based on, and you can expect new single and multi-player modes to come with them. Also, an Android version is on the way. But enough blabbing; get a better idea of how the game works in the video above and download the *free* app right here.
