As many fans expected, Fortnite's mysterious cube has entered Loot Lake. You can watch what happened above, but the cube either melts or sinks into the water, turning the entire lake purple. It's anyone's guess what the long-term ramifications will be, but this development also gave the water the same properties the cube had, bouncing players into the air. If nothing else, that provides you with a fun thing to check out before being picked off by some meanie.
All of this appears to be a setup for Season 6, which may start as soon as next week. Epic has not yet announced a start date, but Season 5 ends on September 25, which may be when we see the next big evolution of the game. For now, enjoy having a giant, bouncy lake to land on.
