Greetings Backlanders,

We are celebrating one month of Hell Clock's release with our third big patch! This time there aren't that many changes, as we focused on the one thing our community has been most vocal about: performance, performance, performance.

We have worked very hard (seriously, type some "o7" for our coder Murilo) to make a performance patch that would actually matter and improve your experience in a meaningful way. We have also drastically reduced Load times after the initial one.

We have recruited some volunteers from Discord to test it out and ensure that we are actually tackling the most pressing problems affecting some high-end builds. So a round of applause to our community members who volunteered their time in the interest of making the game better for everyone: BaZinga, Fatalaris, hardwii, hiragi, Justlfied, Monddoc, Ownage, tetris19023, Tetsuo9999, TheOlBamboozler.

With all that said, a caveat: this patch is not a magical silver bullet that will resolve 100% of performance issues overnight. This is a significant push, and we have seen massive improvements to some users, while others are reporting improvements limited to the 15-20% range. So your mileage may vary, and we will keep working on it.

We have a couple of OG Steam Decks around here, and the performance on the Decks seems to be drastically improved, with the game never dipping below 30 frames, with the exception of some heavy endgame builds that can bring it down to the 15-20 fps range (instead of freezing the game or bringing it down to the "unplayable" 1-2 fps range, as it was before).

Optimizing performance for PC in 2025 is a nightmare as there's such a staggering diversity of devices and setups out there, each with their own quirks. We will keep working on performance during the following months, so please report (respectfully) any lingering issues you might be still experiencing in the Steam forums, Discord, and social media. We don't always reply, but I assure you we read ALL of those in a group effort between myself, Lucy, Carol and Mason.

Lifesteal is dead, long-live Life Leech

The major gameplay change for patch 1.0.3 is a rework of Lifesteal. Originally this was scheduled for patch 1.1 (which will introduce an overhaul of ALL defenses and the enemy damage scaling), but we've seen way too many cases of rookie players equipping a single Lifesteal ring and becoming almost immortal, to the point of accessing areas they were not supposed to yet, and spending 30-60 seconds hitting on a single white mob. It made our eyes bleed, truly.

We decided to scrap the concept of "turning damage into Life" completely, and have introduced something that makes more sense in the broader systems design of Hell Clock. "Life Leech" is now capped at a percentage of your maximum Life every second, and is not cumulative.

In practical terms, it now functions basically as an extra layer of Life Regen per second, but to activate this layer you need to cause damage (at least once every second). It benefits Life stackers more than any other build, and also benefits builds which take advantage of Life Gain and Regeneration bonuses.

Target Dummy is finally here!

You've been asking for this since release, and we've listened: we have added a Dummy to Quixeramobim, allowing you to test your Skills, builds and rotations before descending into Hell.

The Dummy is currently very simple. In the future we hope to increment it with more advanced features such as DPS meters, the ability to spawn multiple dummies, and being able to spawn them as Rares, Uniques or Bosses, as well as adding Resistances and other defensive effects to them.

What's Coming Next?

Patch 1.0.3 should be our last one before our fist Major one: Update 1.1 - Clockmaker's Tools. We are currently on track to hit our September deadline, and we are aiming to land around the time of the Autumn Sale (Sep 29th).

Besides the exciting addition of Crafting, and the much-requested QoL features of Gear Stash, Search/Filter function and Loadouts, we will also introduce a Defenses rework, and a major rebalance of the entire game to increase build diversity and improve the enemy scaling.

Stay tuned to our socials and Steam blogs in the next few weeks for more information on Clockmaker's Tools!

Cheers,
~Mark and the Hell Clock Team
