Honkai Star Rail Astral Slammers Squad is the permanent co-op challenge introduced with Version 4.6. You use Astral Imagea companions or available trial pets to compete in seal-bumping matches, teaming up with other players to earn rewards. HoYoverse confirms that the entry requirement is Trailblaze Level 21 and that the mode has been available since the September 28 update.
To start Honkai Star Rail Astral Slammers Squad, open the co-op activity at Astral Imagea Park and choose your companions. Trial Imageas are available, so collecting rare pets with Trendible Vouchers isn’t required. Learn the collision mechanics in an ordinary match before worrying about harder objectives or reward milestones.
How to unlock Honkai Star Rail Astral Slammers Squad
Reach Trailblaze Level 21 and travel to Astral Imagea Park in the Life Sciences Institute. Use the activity’s navigation marker or travel through the Pet House aboard the Party Car once the region is accessible. The regular story route opens the location, and Finality’s Vision can provide early access to relevant Version 4.6 content.
The main Honkai Star Rail Astral Slammers Squad activity is permanent from the September 28 Version 4.6 update. Its matchmaking and gameplay are separate from the Astral Trendible draw, which has its own limited-time voucher offer.
How matches work in Honkai Star Rail Astral Slammers Squad
The activity is a cooperative version of the seal-bumping minigame: players bring Imagea companions to face enemy baby seals in a pool arena. Check the currently offered companion slots and team arrangement in the lobby, then read the chosen pets’ skills before playing. Your ordinary combat characters’ Relics and Light Cones are not part of this companion-selection system.
In Honkai Star Rail Astral Slammers Squad, the direction of each collision matters. Try to send enemy seals into one another or against a boundary rather than relying on straight, isolated hits. As in Seal Slammers, a useful angle can cause several collisions. Look at how each pet’s ability affects the next bump before choosing which to use.
Can you play with trial Imageas or without a collection?
Yes. The Version 4.6 overview from Icy Veins confirms that you can use trial Imageas or your own collected companions. Start with the provided options to learn the game. You can save your free Trendible Vouchers for a pet you actually want rather than using them just to gain access.
The Astral Imagea collection guide explains the draw, display and trading features, while the Trendible Vouchers guide lists the sources of free draws. Neither collecting a rare Imagea nor purchasing extra vouchers is a requirement listed in HoYoverse’s basic eligibility rules for the minigame.
Best team approach for Honkai Star Rail Astral Slammers Squad
For Honkai Star Rail Astral Slammers Squad, choose companions according to how their abilities fit the arena, not their visual rarity. Read their skill descriptions, practise their launch behaviour and coordinate with the other player where possible. Compare the companion abilities available in your own lobby, then pick two whose bump effects and positioning you can use reliably.
A direct bump is not always the best angle. Try shots that hit multiple seals or use the wall to change a seal’s direction, a tactic established in the earlier Seal Slammers game. If the same opponent keeps surviving, adjust one pet or the launch angle before replacing your whole squad.
Playing with friends and matchmaking
The activity is designed around co-operative play. Invite a friend if you want to coordinate companion choices directly, or check the available matching options when playing alone. Pay attention to the pets offered by the lobby and the rules of the match you enter.
After winning a match, visit the activity’s reward display and check the next challenge shown on your account. The public developer announcement doesn’t specify an exact win total for unlocking a harder difficulty or a rare title, so follow the requirements actually displayed in the live activity instead of relying on an unverified number.
How to progress through Astral Slammers matches
Start with the available matches, learn how your pets collide with the enemy seals, then collect any rewards your clears unlock. If a higher difficulty becomes available, check its unlock condition in the menu and adjust the pets or your approach as needed. Any mode-specific title should be checked in the live reward description.
Honkai Star Rail Astral Slammers Squad rewards and availability
HoYoverse’s event announcement explicitly includes Stellar Jade, Tracks of Destiny and other rewards for Astral Slammers Squad. Check the in-game reward screen for the precise quantities and match requirements. No publicly verifiable list establishes a guaranteed rare title after five Hard wins, so the article no longer presents that claim as fact.
The core Honkai Star Rail Astral Slammers Squad activity is permanently available after the Version 4.6 update. Its availability is separate from Astral Trendible’s limited-time voucher draw, so claim any timed Imagea vouchers while that offer remains live. Check the reward menu for any separate expiry shown beside an individual prize.
What to do after Honkai Star Rail Astral Slammers Squad
Owned Imageas can join a three-pet exploration squad, be displayed in Astral Imagea Park or the Pet House, and be traded through the Trade Plaza. Those collection activities are different from playing Honkai Star Rail Astral Slammers Squad, so you can return to them separately after completing a match.
