  2. From the Level Select screen, highlight Sound Test.

Night mode

This simple trick lets you play any stage with a darker color palette, giving the level a nighttime look. To activate it:

  1. First, enable both the Level Select and Debug Mode cheats.
  2. From the Level Select screen, highlight any stage.

The level will now appear with a nighttime effect, making everything look darker and more atmospheric.

🎮 Gameplay Tips

Whether you're new to Sonic 2 or revisiting it after years, these tips will help you make the most of your adventure through the zones:

  • Collect Rings Often - Rings act as your life buffer. As long as you have at least one, you won't die from most hits. Try to keep 50 or more to access Special Stages and transform into Super Sonic (if unlocked).
  • Use Tails to Scout Ahead - If you're playing solo, Tails will follow you and can occasionally deal damage to enemies. In 2-player mode, a second player can control Tails and help with difficult sections or bosses.
  • Take Advantage of Momentum - Sonic's speed builds naturally on slopes. Use downhill sections to your advantage instead of constantly pressing forward.
  • Explore for Secrets - Some levels hide extra lives, shields, or big ring checkpoints that lead to Special Stages. Don't be afraid to explore upper or lower paths.
  • Bosses Have Patterns - Watch carefully before charging in. Most bosses have easy-to-read attack loops - jump at the right time, and you'll avoid damage.
  • Don't Rush in Oil Ocean or Metropolis - These levels introduce more traps, enemies, and vertical hazards. Patience pays off here more than speed.

Whether you're blasting through Emerald Hill or surviving the traps of Metropolis, mastering these basics will give you the edge you need to reach the final battle against Dr. Robotnik.

🥇 Speedrunning

Sonic the Hedgehog 2 has long been a favorite in the speedrunning community, thanks to its tight controls, momentum-based physics, and level layouts that reward precision and creativity. Whether you're going for a personal best or aiming for leaderboard glory, here are some tips to get you started:

  • Learn the Routes - Every zone has optimal paths that cut down time. Watch top runs to understand where pros jump, roll, and take shortcuts.
  • Master Spindash Starts - A well-timed spindash at the beginning of a level can save precious seconds. Practice revving up and releasing instantly.
  • Control Your Momentum - Momentum is everything in Sonic 2. Use slopes, jumps, and rolling wisely to avoid slowing down.
  • Skip Bonus Stages - For speedruns, Chaos Emeralds aren't necessary. Avoid big ring checkpoints and focus on completing levels fast.
  • Use Debug Mode to Practice - If you're just learning, use Debug Mode to explore stages and practice difficult sections without restarting.
  • Tails Can Be a Hindrance - In solo runs, Tails may accidentally hit enemies or mess with boss fights. Many runners prefer to play as Sonic alone.
  • Glitches & Tricks - Advanced speedrunners use zip glitches and clipping through walls to skip large parts of levels. These take practice but can drastically improve your time.

Speedrunning Sonic 2 is a fun and rewarding challenge - and even just trying to beat your own best time can bring a new layer of excitement to this classic.
