Field Trip is an oddity in Google's app lineup. It comes from Niantic Labs (the people who went on to create Ingress), looks fantastic, and it's made for a very specific kind of user. The app highlights attractions of historical, cultural, and entertainment value in your immediate area, using GPS and services like Thrillist, Zagat, and Cool Hunting to create a "hyperlocal" experience. Of course, any travel app is only good if it works where you are, which was a sticking point for international users.
If you've been paying attention to the news cycle lately, you've probably heard that Google—by way of the obscure "Niantic Labs"—released a game of some kind. You saw a trailer that depicted people discovering hidden energy fields within statues, landmarks, and artistic sculptures. You had no idea what was going on. You signed up for an invite anyway, because like any other weird Google product, you want in regardless of what it is.
We've heard very little out of Google internal team Niantic Labs. Before today, their sole public presence was Field Trip, a mash up of Google Now and various hyperlocal points of interest. The team'' latest creation, Ingress, defies description: it's a virtual reality game in which players are tasked with going to real-world locations to harness a fictional energy source. Also there are two "teams" and every player in the world is one one or the other.
