Upon starting the Blitz app, you'll be greeted with the Game selection screen. If Apex Legends is open and Blitz gets the data from the game, it will automatically forward you to your personalized profile where you can see your stats.
Step 1: Start a Game
Simply jump directly into a game. Blitz will automatically detect the game.
Step 2: Configure the Overlay
Once you're in the game, press Escape to open up the Apex menu, then hover over the combat overlay. A cogwheel will appear, which you can press to open up the menu and customize the overlay to your liking.
That's it! You're now ready to enhance your Apex Legends experience with Blitz.
