| Mortal Sin Is 25% Off + What’s Next | 2026-05-15 | Hi everyone!I wanted to share a quick update on what I’ve been working on, what’s next for Mortal Sin, and what’s coming later with my next game.For full transparency, since the last major update, I’ve spent most of my time working on my new project. I’ve taken a lot of what I learned from Mortal Sin, and I believe I’ve found a direction that is much more focused and hopefully something that will resonate with a lot of people.For much of Mortal Sin’s development, I often felt like I was designing by the seat of my pants. I would add something cool, then figure out how it fit into the bigger picture as I went. With this new project, I’ve refin |
| Blitz Ascension | 2026-03-19 | Blitz is here.This is something I’ve wanted to do for a while, a mode that strips Mortal Sin down to its core and pushes it as far as it can go. Faster runs, higher pressure, more meaningful decisions, and a real reason to compete.Every run is a fresh start. Every day is a shared challenge. And every second matters.Alongside Blitz, I’ve added a new boss, new enemies, new elite modifiers, and a number of balance changes to tighten things up across the board.New Mode: BlitzBlitz is a roguelike within a roguelike. It focuses entirely on skill and efficiency.Your curse meter increases over time instead of based on progress, so you cannot take you |

| Final Boss Flow Update | 2025-12-18 | Hello Sinners! I have been cooking up some new content and features, but they need a bit more time in the oven.

| 🧡 Nominate Mortal Sin for "Best Game You Suck At" Award! | 2025-11-24 | Hey, guys! The Steam Awards 2025 has just started, and it's definitely one of the best moments to allow the community to give Mortal Sin a chance to receive the support and votes for it. Mortal Sin is a blast for me to work on, and the fact that I was able to push the launch of the game this year and also be part of this event means a lot. I really hope that this announcement gives you the same feeling as it gives me. As a humble request, please nominate my game for the "Best Game You Suck At" award! Through all the trials and enemies being slashed, I'm already grateful enough that I have players like yourselves to keep this project going. 🔥 |
| Remnants of Sin Update | 2025-10-27 | This update is mainly about two things: making runs feel more worth chaining, and pushing performance further. The new Sin Remnants system lets you pick one of three on death or when continuing to the next run, and some of them can completely flip how your next round plays. The idea is to make the next run feel tempting instead of starting over from zero.On the performance side I hit a lot of the obvious wins across blood, projectiles, foliage, hit detection and lighting. I still want to bring RAM down more and I am still not happy with Steam Deck performance yet, so that remains a priority going forward.New Feature — Sin RemnantsNew system t |

| Skins of Sin Update | 2025-09-29 | For this update I wanted to make the classes feel more distinct while also expanding the game’s meta progression. To do that, I’ve added a set of skill-based unlockable objectives that challenge you to play in specific ways. These objectives reward you with unique class skins, giving both a new visual identity and another layer of long-term goals to chase.New ContentAdded unique class skins with 3 variants per character (48 total).Skins are unlocked by completing special objectives such as defeating multiple enemies in a single attack, finishing areas under time limits, or acquiring specific skills and items.Every class still has its classic |
| Hotfixes 8/31 | 2025-09-01 | Hello Sinners, Thank you so much for the incredible support during launch. Mortal Sin has been trending on Steam and the response has been amazing to see. I’m truly grateful for all of you who picked up the game, shared it, and gave it a shot. Here’s what’s in today’s update: Fixed the Hunter’s Eviscerate combo to work with non-spear weapons such as the Halberd and Guan Dao. Removed large mushrooms in one of the cave rooms that could box players in. Technically you could crouch to get out, but since crouch is rarely used (and some of you might only be learning it exists reading this), I’ve adjusted the room accordingly. Fixed a soft lock in t |

| Arise, Sinners - Mortal Sin Full Launch coming August 29th, 2025! | 2025-08-22 | ⚔️ Arise, Sinners. The time is nigh.

| Unique Items, Loot Overhaul, Accessibility Update | 2025-07-25 | Hey everyone, Before we dive into the full patch notes, I wanted to make a quick request: I’m looking for a Spanish (Spain) localizer, ideally someone who actively plays the game like our Russian and Chinese translators. If that sounds like you, or you know someone who might be a good fit, please reach out.This update is focused on improving early and mid-game retention. I’ve been looking closely at the data, and far too many players are dropping off early. As much as I’d love to spend all my time adding new challenging content for hardcore players, over 90% of people never even reach that point. I want more players to actually experience the |

| Quest Update Part I | 2025-06-20 | This update introduces a set of brand-new quests, each built around the positional-style objectives I’ve found to be the most fun and intuitive. These quests use the special floor plate system as a base, with unique twists that encourage movement, awareness, and experimentation. I’ve also made several balance changes, gameplay improvements, and bug fixes to help smooth out the overall experience.🔥 New Quests (8 Total)I’ve added 8 new quests, all focused on spatial challenges, survival mechanics, and dynamic enemy behavior:Aberration Defeat the mutants—faster, tougher variants with elongated limbs and aggressive movement.Seal of Slaughter Sta |
| Hit Hard, Look Good | 2025-06-06 | Took some time this update to sharpen the feel and addictiveness of the core gameplay. I thought things were in a good place—until I played Doom: The Dark Ages and realized my feedback was still a bit soft. Now? Hitting and killing things has never felt better. Hopefully these changes make the experience even more immersive and satisfying. Enjoy!EnhancementsCamera Shake Added – Hits now trigger screenshake based on their strength. This includes melee attacks, gunfire, magic staves, damage taken, and certain class abilities. You can disable it in settings—if you really want to ruin my day—but it massively improves the feel of combat.Spell Reco |
