Throughout Season 2 of Apex Legends, you will have the opportunity to unlock unique rewards. You will evolve from level 1 to level 100, and at each new level you will unlock music packs, emotes, loading screens, Apex Coins, skins, and even Apex crates.
There is the Battle Pass for 950 Apex Coins, and the Battle Pass Bundle for 2,800 Apex Coins — which will instantly grant you 25 levels for the Battle Pass.
Fortunately, you won't need to buy the Battle Pass to be able to play as Wattson.
