Anthem is one of the more interesting game announcements (so far) at E3. Featuring what appears to be jump in/jump out co-op, you can explore the wilderness outside of civilization, fight enormous creatures, and explore with your friends to find loot.
There are multiple Javelin exosuits to choose when braving the dangers, from the more balanced Ranger to the heavy hitting Colossus. As a Freelancer, you can choose to go wherever you want and fight as a team.
We are really hoping to see more of Anthem at E3, along with a release date of right now.
