"Undersea Mystery": ocean-themed update

"Undersea Mystery" was Free Fire's first ocean-themed campaign, starting April 8. The update added a whirlpool at the dam that grants access to the new Underwater Kingdom, Fishing Lagoons across the map with buffs and loot, and replaced the traditional Blue Zone with the Aquatic Zone and high-tier gear. It also brought a reskinned Whale Plane, themed airdrops in Clash Squad, new character Ray, and a sequential login system with mascot Pyro.
