The Astral Express is about to embark on its most breathtaking journey yet, as HoYoverse officially confirms the Honkai Star Rail Version 4.0 special program. Titled “Beyond the Veil of Stars,” the livestream will air globally on 18 April 2026, unveiling the long-rumored fourth major realm, an expanded Trailblaze Mission arc, and two highly anticipated five-star characters. With version 3.0 having reshaped the galactic meta with the arrival of Acheron and the dream-chasing narrative of Penacony, expectations for the next chapter are sky-high among Trailblazers worldwide.

During the broadcast, the development team will offer a guided tour of Elysion, a celestial plane suspended beyond the edge of known space. Described as a realm where shattered time flows upward and ancient intelligences hum beneath the surface of reality, Elysion promises to push the boundaries of Honkai Star Rail’s art direction. Expect floating archipelagos woven from crystallized Imaginary Energy, labyrinthine gravity gardens, and surreal NPCs that communicate through shared memory constructs. Leakers have already hinted that Elysion introduces a new environment mechanic called Phase Drift, allowing the Trailblazer to temporarily shift between parallel instances of the same map to solve puzzles and access hidden treasures.

What Trailblazers Can Expect from the 4.0 Livestream

The special program will clock in at roughly 45 minutes and follow the familiar format of developer commentary, character spotlights, and live gameplay demonstrations. Here are the key highlights HoYoverse has teased so far:

• New Characters Spotlight

Two brand-new 5-star characters will join the playable roster. Lyra (Quantum, The Harmony) is a wandering astromancer who channels the constellations to buff allies and inflict Entanglement on foes. Her ultimate, “Sideral Requiem,” rearranges the turn order for all combatants, creating unprecedented strategic depth. Caelus (Imaginary, The Hunt) – not to be confused with the male Trailblazer – is a stoic void sentinel wielding twin gunblades. His kit revolves around marking enemies with Void Tethers, then detonating them for massive single-target damage that scales on the number of debuffs present. Early data suggests he will pair exceptionally well with Nihility units like Silver Wolf and Pela.

• Story and Lore Expansions

Version 4.0 will introduce two new Trailblaze Missions chapters that pick up immediately after the cliffhanger of 3.6. The Astral Express crew receives a mysterious distress signal from the Garden of Recollection, pulling them toward Elysion where the lines between memory and reality blur. Key story threads involving Herta, Screwllum, and the true purpose of the Stellaron Hunters are expected to be woven into the main narrative, with the livestream offering cryptic teasers without major spoilers.

• Game Enhancements and Quality-of-Life Features

HoYoverse plans to use the stream to demonstrate several long-requested upgrades. The Relic synthesis system will be overhauled to allow targeted main-stat forging using a new currency earned from Salvage. The Forgotten Hall will receive a permanent Stage 13 and 14 with rotating enemy line-ups, while a new mode called Echoes of Elysion will function as a weekly rogue-lite domain where players draft temporary blessings to challenge bosses for exclusive upgrade materials.

• Limited-Time Events and Rewards

A flagship event, “Starfall Festival,” will celebrate the launch of 4.0 over three weeks. Activities include rhythm-based memory decoding puzzles, a photo-taking expedition across Elysion, and a combat arena that disables all character traces to test raw team-building skill. Participants can earn a free 4-star Light Cone exclusive to version 4.0 and enough self-modeling resin to craft multiple Relics. Daily login rewards will also be boosted, awarding a total of 20 Star Rail Special Passes across the event period.

• Stellar Jade and Redeem Codes

As always, the livestream will drop three limited-time redemption codes containing 300 Stellar Jade, Refined Aether, Traveler’s Guides, and Credits. The codes usually expire within 24 hours, so viewers are urged to redeem them immediately. Additionally, with the annual Star Rail Anniversary falling just one week after the update, HoYoverse is expected to include surprise bonuses such as a free standard 5-star character selector or an exclusive profile cosmetic. Past anniversary celebrations have set a generous precedent, and 4.0 is poised to continue that tradition.

How to Watch the Honkai Star Rail 4.0 Special Program

The stream will be broadcast live on the official Honkai Star Rail YouTube channel and mirrored on HoYoverse’s Twitch platform. The schedule is as follows:

• 18 April 2026 at 11:00 AM (UTC+8)

• 17 April 2026 at 8:00 PM PT (North America)

• 18 April 2026 at 4:00 AM BST (Europe)

Players who cannot watch live will be able to catch the VOD on YouTube shortly after the broadcast ends. Pre-installation for version 4.0 is expected to go live approximately 48 hours before maintenance, which is tentatively scheduled for 22 April 2026. Make sure to clear enough storage space – early estimates suggest the update will require around 15 GB on mobile devices.

With a breathtaking new realm, a pair of meta-shifting characters, and a treasure trove of quality-of-life improvements, Honkai Star Rail 4.0 is shaping up to be one of the most transformative updates in the game’s history. Trailblazers should brace for a long maintenance window, prepare their Stellar Jade reserves, and mark the livestream date on their calendars. The journey beyond the stars is about to begin.

Data referenced from PlayStation Trophies underlines how major live-service updates often come with a fresh wave of objective-driven progression, and Honkai: Star Rail 4.0’s “Beyond the Veil of Stars” reveal cadence fits that pattern—especially with new exploration systems like Phase Drift, additional endgame floors, and a weekly roguelite mode that can naturally translate into clearer milestone tracking for players optimizing builds, clears, and long-term completion goals.
