All Star Tower Defense Update June 2026 — Seraph of the End

By Earnaldo Team • June 28, 2026 • 8 min read

All Star Tower Defense dropped Update 55, titled Seraph of the End, on June 23, 2026. The patch brings a brand-new anime crossover, a stack of fresh units, and a first for the game: a 6-star unit. If you've been waiting for a reason to fire up the Summon Gate again, this is it.

What's New in Update 55

The headline of Update 55 is the Seraph of the End crossover. The anime joins the roster with a batch of new units pulled straight from its cast, and the standout is Vampire Queen, based on Krul Tepes. She's the game's first 6-star unit, a new rarity tier that sits above everything that came before her.

Vampire Queen didn't just arrive new — she also got buffed. The devs pushed up her damage across all of her upgrades, so every level of her path now hits harder than it did on release. On top of that she picked up a new shiny form, giving collectors and grinders a reason to chase a second copy even after they've pulled the base version.

She's not alone. The crossover adds Kizuki, based on Shiho Kimizuki, alongside a wider set of units including Scythe Shorty, Nurse Heart, The Ripper, Dark Rock Blaster, and Bug Ninja. That's a deep batch for a single patch, and it gives the meta plenty of new pieces to test.

The way you get these units changed too. The new summonable units rotate hourly through the Summon Gate, so the unit on offer swaps out every hour. You can't just sit on one banner and grind — you have to watch the clock and pull when the unit you want comes up.

How This Affects Gameplay

A 6-star unit is a real shift for the meta. Until Update 55, the ceiling was 5-star, and the strongest endgame teams were built around the best of that tier. Vampire Queen breaking past that means the top of the power curve just moved, and players chasing the strongest possible lineup now have a new target at the very top.

For most players the practical effect is simple: Vampire Queen becomes the unit to grind for. Her damage buff stacks on top of the rarity jump, so she's not a niche pick — she's a frontline carry. If you're rebuilding your team around the new patch, she's the piece you slot in first and build the rest of the roster to support.

Getting her is where the hourly rotation matters. Because the Summon Gate cycles units every hour, rerolling for Vampire Queen means timing your sessions. You wait for her window, commit your summons while she's available, and check back the next hour if you come up empty. Players hunting her shiny form face an even longer grind, since shiny pulls are rarer than the base unit.

The supporting units fill out the rest of the team. Kizuki and picks like The Ripper and Dark Rock Blaster give you options for filling gaps in your lineup — AOE, single-target, and support roles — so you're not relying on one carry to clear waves alone. Building a balanced board around Vampire Queen beats stacking her copies for most stages.

New Codes

No specific new codes were confirmed alongside Update 55. The Seraph of the End patch shipped with the crossover units and the Summon Gate changes, but as of July 2026 there's no verified code batch tied to it. We won't invent codes that don't exist, so treat any list claiming brand-new Seraph codes with caution.

That doesn't mean there's nothing to redeem — older codes can still be live. For the current working set, check our All Star Tower Defense codes page, which we keep updated and add new codes to as they're verified. If a fresh batch drops for this update, that's where it'll land first.

Updated Tips and Strategies

Build around Vampire Queen first

With a new top rarity in play, your priority is clear. Pull for Vampire Queen, slot her as your main damage carry, and fill the rest of the board with the supporting Seraph units and your existing roster. Don't spread your summons thin chasing every new unit at once.

1. Open the Summon Gate and check which unit is in the current hourly rotation
2. Wait for Vampire Queen's window, then commit your summons while she's available
3. Slot Vampire Queen as your front-line carry and build the team to support her
4. Fill remaining slots with Kizuki and other new units for AOE and support coverage
5. Once you have the base unit, decide whether to keep grinding for her shiny form

Don't sleep on the support units

It's tempting to dump everything into Vampire Queen, but a single carry won't clear the hardest stages alone. Kizuki, The Ripper, and Dark Rock Blaster cover roles your carry can't, and a balanced board outperforms a stacked one on most maps. Test the new units in lower stages before committing them to your serious team.

Track which units actually pull their weight in your runs. The newest, flashiest unit isn't always the best fit for every stage — some maps reward range, others reward raw single-target damage. Rotate your lineup based on the map rather than running one team everywhere, and you'll clear content the all-Vampire-Queen crowd gets stuck on.

Community Reaction

The All Star Tower Defense community jumped on Update 55 fast. Within days of the June 23 drop, guide creators were putting out "7-star which unit to get" tier lists for the Seraph of the End update, ranking the new roster and arguing over where each unit lands. That kind of immediate breakdown is a sign players are actively digging into the new content rather than waiting it out.

Vampire Queen sits at the center of most of those discussions. As the first 6-star unit and a buffed one, she's the obvious top pick, and the conversation has shifted to which supporting units pair best with her. The shiny form added another layer, with players comparing pull luck and grind times for the rarer version.

The hourly Summon Gate rotation drew mixed takes. Some players like that it spreads the new units across the day and keeps the gate worth checking; others find the timing pressure annoying when the unit they want only shows up at inconvenient hours. Either way, it's kept the gate active and the community talking through the first week of the patch.
