The Battle Pass includes:

Season 1 kill banners for everyone
1400 apex coins
1 guaranteed purple lootbox/1 gold lootbox
4 regular lootboxes
20 blue weapon skins
2 legendary weapon skins for the Prowler and Havoc
3 shitty skins for mirage, lifeline, and wraith
Also some banners, intro quips, and special season ranks, which will hopefully be separate emblems from pre-season ranks
