The Blackout Beta will toss you into the level even before the game officially starts. This pre-game lobby is called the Drop Zone. Here you can learn the map and try out some weapons and understanding of the game systems and mechanics. But note, once the match begins, you won’t bring any of the weapons or equipment used in the Drop Zone with you into the match.
Once a number of players have joined the lobby a countdown clock will start and then it’s time to get down to the business.
