Mk12 is getting an upgradable skin with the next update
The next contraband crate will contain a new upgradble skin for Mk12, as reported by dataminer ASJ_sapphics.
Along with the skin itself, players will receive a custom deathbox for slain players, as well as a killfeed frame. When exactly the items will appear in PUBG: Battlegrounds is not yet known.
New batch of cosmetic items, developed in partnership with eSports athlete Wasu "Ezqelusia" Surapakornniti from Thailand, went on sale in the PUBG: Battlegrounds in-game store a day before yesterday.
