Get Free Call of Duty: WWII Gear
Now that you're done being altruistic, you can focus on another thing that you get out of the Call of Duty: WWII beta. You get some loot that only beta players will have.
If you play in the Call of Duty: WWII beta, you get the exclusive MP Private beta combat pack. This includes a special helmet that you can wear in game and that will show up when you are in the Headquarters area.
You'll also get a calling card and an emblem that is only available if you play the beta. Sure, a lot of people will have them, but it's a small reason to spend time playing the Call of Duty: WWII beta.
