This past weekend Gearbox Software rolled into Guardian Con in Orlando, where they revealed a variety of new Borderlands 3 details during a pair of panels. The biggest news is that Borderlands 3 will have an Apex-Legends-style ping system, which should make for easier communication. You can check out a brief demo of the ping system, below.

In addition to the ping system, Borderlands 3 will now allow even more friendly competition between you and your teammates with 4-player free-for-all duelling. On the matchmaking front, you’ll be able to join up with groups based on what kind of activity you’re looking to do and play single-player or local multiplayer when the game searches for online players to pair you with. There are also a number of ways you can continue to connect with your favorite teammates, even when you’re not playing together – you can mail items to your buddies and if you pick up a particularly badass piece of gear when a friend isn’t around, it will appear in a vending machine in their game so they can buy it later.
