2XKO Uses a Proprietary Riot Games Engine for Its Combat

The fighting title 2XKO, initially known as Project L, does not rely on commercial engines. Riot Games develops and uses its own internal technology to build this game, allowing them to control every technical aspect and optimize it for their specific design goals. 🎮

An Engine Built for Precision and Speed

The decision to use a proprietary engine responds to the unique technical demands of a modern fighting game. The team prioritizes two key factors: absolute precision in registering player inputs and the constant fluidity of animations. Although Riot does not share deep technical details, this internal control allows them to fine-tune performance to achieve competitive and reactive gameplay.

Key Advantages of Internal Development:
  • Specific Optimization: The engine is tailored to handle network and combat logic at high speed, something vital for the genre.
  • Total Control: Developers can implement technical features without relying on the limitations of a third-party engine.
  • Artistic Integration: The technology aligns directly with the cel-shaded visual style, processing effects and animations coherently.
The technical priority lies in maintaining a constant and high frame rate, which is essential for the competitive gameplay the genre demands.

Visual Aesthetic: 3D Models with a 2D Soul

The graphical aspect of 2XKO fuses three-dimensional models with a shading technique called cel-shading. This method applies flat colors and defined edges to the 3D models, creating the illusion of a traditional 2D illustration coming to life. The style is a hallmark of Riot, visible in League of Legends and the Arcane series, and is used here to unify the game's world. ✨

Elements That Define the Artistic Style:
  • Stylized Shading: Characters and stages are processed to eliminate smooth gradients, emulating the stroke of a cartoon.
  • Coherent Visual Effects: The particles from super moves and abilities also follow this aesthetic, avoiding breaking the visual immersion.
  • Expression and Clarity: Every movement and attack is designed for the player to perceive it with instant clarity during combat.

Fluidity as a Pillar of Design

The team dedicates monumental effort to creating fluid and expressive animations. This fluidity is not just a visual detail; it is a functional requirement. It allows the player to interpret each of the opponent's actions and react in fractions of a second. In a genre where every frame counts, a delay or an unclear animation can decide the outcome of a match. The philosophy is simple: a spectacular combo loses all its value if the game doesn't respond instantly. ⚡
