Honkai: Star Rail version 4.3 launches June 1

Honkai: Star Rail version 4.3 launches June 1 is part of Gameforce Asia's May 22 news briefing, tracking the releases, platform moves and live-service updates most likely to affect what players watch next.

Honkai: Star Rail version 4.3, The Lethe Below the Living, launches on June 1, and HoYoverse is clearly keeping the train packed. The update continues the Planarcadia storyline, introduces Mortenax Blade and brings another round of events, systems and character-driven drama for players who have somehow kept their Stellar Jade discipline intact. The bigger headline for crossover fans is that the Fate/stay night: Unlimited Blade Works collaboration is also being positioned for its return in July, which gives version 4.3 some extra long-term gravity beyond the immediate story update. Star Rail's strength has always been its ability to make each patch feel like both a content drop and a fandom event. The risk, as always, is exhaustion. But for players already invested in its characters, myth-building and gacha rhythm, June 1 looks like another major checkpoint.
