General Design

  • Avoid bad or regular level design ideas. Apply classics ideas on 3d space;
  • Mechanics from several games, specially classics in 3d;
  • Use of slope physics in the scenario and terrain for gaining/losing speed and momentum;
  • Branched paths with more risk/reward on each paths;
  • No linearity, automation, scripts or event based, play creativelly instead of having the game playing for you!;
  • Sonic CD inspired exploration: interconnected level, no unnecessary bottomless pits on every level or insta kill hazards, ways to change paths;
  • No rank system locking you. Make your best score and time on game modes;
  • Warp Rings to go to Special Stages;
  • 4 gameplay modes - Score Attack, Time Attack, Ring Attack and Trail Attack;
  • Explorable background with itens, enemies and secrets for devoted players;
  • Special Stages are their own levels;

  • Exploration areas inside the levels, with secrets, battles, collectables and warp rings;
  • Complex and fast battles with infantry badnicks and tactical gunners;
  • Skills uses energy, no more fun-break with homing attack or boost turning enemies into cones. No more brainless boost for Sonic, use Spin Dash instead and take advantage of the scenario;

  • Boss mechanics with influences from Adventures and Sonic CD death race;
  • War machine Metal Sonic and Metal Knuckles designs;
  • Models based on Sonic 06 sillhouette to the realistic world;
  • Cutscenes use ingame graphics with Unreal Sequencer, with Portuguese/English dubs.


  • Authored in Epic Unreal Engine 4, the most advanced and leading game engine software;
  • Uses a custom efficient and optimized codebase for managing its gameplay elements;
  • Uses lastest graphics technologies to bring the most realistic effects such as raytracing shadows and reflections, global illumination, volumetric clouds, parallax occlusion mapping, physical based shaders, gpu particle effects, post processing and others;
  • Procedural modelling, shaders and objects placement were used to develop the game faster with the best results possible.
  • Compartibility with DirectX 12 for maximum speed and best hardware use.
