EA's E3 2018 showcase ended with an extended discussion and gameplay demo of Anthem before revealing the game's release date. However, if you can't wait to throw down your money, then you can pre-order it now and receive some bonuses in return.

Everyone who pre-orders Anthem will receive VIP demo access and an in-game Founders banner, but you'll get more content depending on which version you choose. The Standard edition comes with a legendary weapon and the Legion of Dawn Armor Pack for the Ranger Javelin.
