Update 1.4 is live!

Undead Onslaught – Update 1.4 Patch Notes

Hello, Villains of Undead Onslaught!

Update 1.4 is finally here — and it is one of the most substantial updates the game has received so far. This update introduces brand-new content, expands progression, and revisits several core systems to improve clarity, balance, and long-term replayability.

Below are the full patch notes for Update 1.4.

🗺️New Map – Von Eldrath Castle

A second map has arrived.

Von Eldrath Castle, the ancient stronghold of the Von Eldrath Bloodline, is now playable. The castle is currently under siege by Dwarven forces and their Fae allies.

• New playable map with a unique layout and encounter flow • Distinct pacing and enemy compositions compared to the original map • The addition of a second map allowed us to review overall balance and smooth out progression pacing across the game

Relieve the siege of the castle… and perhaps its enigmatic ruler will take notice.

“She mentioned to look for her coming at first shadow on the fifth night. At dusk, look to the East.”

🩸New Playable Villain – Seraphyne Von Eldrath

A brand-new Villain joins the roster.

Seraphyne Von Eldrath enters the fray, hungry for the blood of the innocents.

• Fully playable Villain with unique mechanics and talents • Specializes in Bleed, Blood synergies, and risk–reward gameplay • Features a unique unlock condition tied directly to the new map

Keep a close eye while exploring Von Eldrath Castle — her arrival is anything but ordinary. You can read more about her here: view

⚔️New Basic Evolutions

We’ve added a major expansion to basic weapon evolutions.

• New basic evolutions that do not force hybrid damage-type playstyles • Each damage type now has two new evolutions • A total of twelve brand-new evolutions added • Focused, single-damage-type builds are now fully viable • Hybrid builds remain possible, but are no longer mandatory

This change greatly expands build identity and experimentation.

🔥Onslaught System 2.0

The Onslaught system has been fully reworked.

• Onslaught is now configured before the run • Difficulty is increased manually on a per-run basis • No longer functions as a dynamic difficulty system • Gives players full control over challenge and risk

This makes difficulty scaling more transparent, intentional, and player-driven.

✨Relics Update

The Relic system has received a major update in 1.4.

• Brand-new Relics UI • Multiple new Relics added • Balance updates to existing Relics • Improved clarity and consistency in Relic descriptions • Better alignment with newer damage types and build synergies

While Relics were already part of the game, this update significantly expands their impact on builds. You can read more about the Relics update here: view

📜Necronomicon Overhaul

The Necronomicon has received a major visual and functional overhaul.

• Completely refreshed visual design • Improved layout and navigation • Increased interactivity across pages and entries • Many entries now feature short visual previews of mechanics and effects • Clearer presentation of systems, synergies, and progression

The Necronomicon is now designed as a true in-game reference tool.

🧟Wave Overhaul

Enemy waves have been significantly reworked.

• Updated enemy compositions • Improved enemy behavior and engagement patterns • Better escalation of difficulty throughout a run • Clearer identity and roles for enemy types

🌳Talent & Build Improvements

Building on the changes introduced in 1.3.5, Update 1.4 continues refining talent structure and build clarity.

• Further tuning of the new talent tree philosophy • Earlier access to damage-type conversions • Improved consistency across Villain talent trees • Fewer dead or overly restrictive talent choices

💬 A Note From the Team

Before we wrap this up, we want to address something openly.

We know this update took much longer than originally anticipated — and we’re sorry about that.

Real-life obligations and unexpected pressures put significant time constraints on our small indie team, and that inevitably affected our development pace.

Undead Onslaught is being built by a small group of people who genuinely care about the game, and while we’re doing our absolute best to keep it evolving, future updates may arrive at a slightly slower pace than before.

That said, we remain optimistic.

The next update is currently planned to be the launch update, though depending on how things shape up, there *may* be a 1.5 update before final release. We’ll have a clearer picture — and more concrete information — by the end of Q1 2026.

Until then, thank you for your patience, your support, and for sticking with us on this journey.

Happy holidays to everyone, and thank you again for waiting with us.

Sorry for having to make you wait a bit longer — but awesome things come to those who wait.

With gratitude,

The Wish App Games Team
