Survival Supply System/Season 1
What is the Survival Supply System? The Survival Supply System is a free form of progression in BATTLEGROUNDS unlike the Event Pass where you need to buy a pass in order to unlock all the rewards. By completing in-game missions, you earn XP and upon filling up the 'Survival gauge' every time you earn both a 'Survival level' and rewards. Missions get refreshed daily and weekly.
There is no max level and no optional premium pass to purchase. The Survival Supply System is a semi-permanent Reward System, meaning that for the foreseeable future, there is no deadline to when you have to earn rewards by as there was with the Event Pass. PUBG Corp is discussing long term plans to make the Survival Supply System a seasonal thing to keep rewards fresh. 
The Survival Supply System was introduced in the Test Server PC 1.0 update #21.
- Event period: September 12th - December 19th, 2018.
