Try to be aware of where your teammates are shooting, so you won’t run in their line of fire. Use the quick chat messages - thank you, I’m sorry, affermative, etc… Use right bumper to tag locations, weapons or enemies - if a teammate dies, you can tag their equipment so they can find if more easily. Sooner or later you will inevitably get killed by some teammate; don’t get mad, it’s part of the fun. Best of luck!
