Note that each Supply Drop provides random prizes with a chance to win the top prize. Prize value increases and new prize types are unlocked when the Landing Zone is upgraded. Prize tiers are: Enlisted (gray), Professional (green), Elite (blue), and Legendary (gold), containing prizes from small amounts of resources, to League Shields, to boosts, to 1000 Celerium. Players receive one Supply Drop every 12 hours, and can also earn one additional Supply Drop everyday at 16:00/17:00PST (DST dependent) by watching an in-game ad, or purchase up to 10 more Supply Drops a day for 100 Celerium each.
