Your competitive rank is based on matches played in “Ranked” matchmaking. You can go up or down in your competitive rank.
Your progression level increases based on various accomplishments, such as kills, assists, and wins. You can also complete the daily and weekly challenges to increase your progression level. You unlock SAW Packs based on increasing your progression level.
Your Arena Pass level is also based on your various accomplishments, such as kills, assists, wins and challenges. However, the Arena Pass is seasonal, and will expire at the end of each season. You will be able to keep your unlocked cosmetics.
