The Splatter Manga Soulslike: Visually Stunning and Brutally Hard

Anyone seeing material for the first time from Mortal Sin might rub their eyes in surprise: high-contrast comic style, highly saturated colors, and shattering melee combat. The game throws you from a first-person perspective into nightmarish, alchemistic dungeons full of hideous monstrosities.

What looks like a pure niche gimmick turns out to be one of the smoothest and most satisfying first-person melee shooters of recent years.

The Gameplay: Dismember with Strategy and Flow

At its core is an extremely solid combat system. Instead of mindlessly hammering the mouse button, Mortal Sin demands precise timing, good movement, and targeted exploitation of enemy weaknesses:

  • The Combo System: The chaining principle of strikes, parries, kicks, and dashes ensures an addictive game flow.

  • Targeted Dismemberment: Enemies can be strategically dismembered. Strike off the ogre's weapon arm or take out the shooter's legs – the dismemberment mechanic directly affects the threat in the room.

  • Durability as a Motivator: Weapons and armor pieces wear out extremely quickly. Since broken equipment is irretrievably lost, you must constantly adapt your tactics and spontaneously pick up new gear from the ground.

  • Class Diversity: Whether a heavy berserker with a greatsword, nimble monk, or mage – the different classes radically alter the gameplay feel and synergies.

Graphics & Sound: An acquired taste but brilliantly designed

The bright comic aesthetics might initially put some off, but it has a brilliant gameplay advantage: backgrounds are muted in color, while threats, enemy attacks, and important interaction points stand out in bright primary colors.

If the standard color set doesn’t suit your taste, you can choose from numerous different palettes in the options. The heavy, bloody sound perfectly underscores every single hit.

Technology & Performance: Our Test System

Mortal Sin forgoes resource-hungry photorealistic graphics and instead focuses on blazing frame rates – essential for such a fast melee game.

Test Setup:

  • Laptop Model: MSI Vector GP76 12UH

  • Processor (CPU): Intel Core i7-12700H (14 cores, 20 threads, boost up to 4.7 GHz)

  • Graphics Card (GPU): NVIDIA GeForce RTX 3080 Laptop GPU

  • Memory (RAM): 16 GB DDR5

Performance Impressions:

On our reference system, the game ran absolutely smoothly. Even in densely packed rooms with dozens of enemies, flying limbs, and particle effects, frame rates remained off the charts. The game barely uses the hardware, runs extremely stable, and conserves the system admirably. It also runs buttery smooth on weaker laptops without issues.

Pros & Cons

What we like:

  • Unique, extremely fluid, and powerful first-person combat system

  • Tactical depth through targeted dismemberment mechanics

  • High replay value thanks to diverse classes and loot dynamics

  • Customizable color palettes for the visual style

  • Excellent technical optimization and high FPS

What we like less:

  • The visual style and high color saturation may not suit every taste

  • High difficulty level can initially overwhelm beginners
