In Halo Infinite, you can complete various weekly and daily challenges to earn XP in order to level up in the Battle Pass to earn a ton of rewards. In addition to this, after you complete all of your weekly challenges, the ultimate challenge will unlock which will offer you an ultimate reward upon completion.
Abbey Lime weapon coating, which can be applied to the S7 Sniper Rifle, is the ultimate reward for completing the first week’s ultimate challenge. In order to grab it, you will first need to complete all of the weekly challenges that you can find in the battle pass section of the game.
After that, the ultimate challenge will get unlocked, which is to kill 15 enemy Spartans with a headshot in PvP matches in any mode except bot matches. Once you complete it, Abbey Lime will automatically be added to your Weapons Bench.
The weekly and ultimate challenges reset every Tuesday at 6 PM GMT / 6:00 PM UTC / 1 PM ET / 10 AM PT, so make sure you complete all of the required challenges before the said time to obtain Abbey Lime skin.
