Plan your next Earthion session

Our independent guide breaks down Earthion’s documented elements—level design, difficulty choices, audio, visual filters and platform services—so you can approach each aspect with clear expectations and avoid assumptions about hidden mechanics.

01 / THE GUIDE

Level Pattern Study

During the first minute of a level, note enemy entry points and wave timing. Comparing these observations across stages helps you anticipate threats without relying on undocumented cues.

  • Observe the first wave of enemies to learn timing.
  • Memorise boss attack patterns for better avoidance.

02 / THE GUIDE

Difficulty Comparison

Finish a level on Hotshot, then replay the same level in Challenge mode. Record any differences in enemy density or projectile speed to gauge the added difficulty.

  • Start on Hotshot to learn level layouts.
  • Use Challenge mode to test higher skill thresholds.

Sound Cue Awareness

Play a stage with volume at a comfortable level and focus on the music. Identify recurring motifs that align with boss entrances, using them as timing references.

  • Use headphones to hear subtle effect cues.
  • Notice musical shifts that often precede boss introductions.

04 / THE GUIDE

Scanline Calibration

Select a familiar level and toggle through low, medium and high scanline settings. Note which intensity provides the clearest view of enemy silhouettes for future runs.

  • Try low, medium and high scanline levels to find a comfortable view.
  • Combine scanlines with full‑screen mode for a more authentic arcade feel.

05 / THE GUIDE

Leaderboard Review

After finishing a run, open the online leaderboard and compare your score breakdown by level. Target stages with lower scores for incremental improvement.

  • Use a DualShock or DualSense controller for the intended input experience.
  • Remote Play on TV lets you stream the game to a television.
