With Journey, thatgamecompany (TGC) continues its tradition of delivering simple gameplay and accessible controls in an interactive environment that invites players to explore and experience emotional chords that are still uncommon in video games.
An exotic adventure with a more serious tone, Journey presents TGC’s unique vision of an online adventure experience. Awakening in an unknown world, the player walks, glides, and flies through a vast and awe-inspiring landscape, while discovering the history of an ancient, mysterious civilization along the way.
Journey’s approach to online play encourages players to explore this environment with strangers who cross their path from time to time. By traveling together, they can re-shape the experience – creating authentic moments they will remember and discuss with others
Here's the E3 trailer.
