About Echo Zero
In the dark, all you have is your echo. And every ping has a price.
Dive down a pitch-black cave. Tap the screen: a sonar wave lights up the walls, spiked traps and energy cores for a few seconds, then everything fades to black again. Remember what you saw, ping less, dive deeper.
- Drag to swim, tap to ping, hold for a big ping.
- Balance your energy: ping too often and you run dry, ping too little and you hit a wall.
- A collapse from above keeps pushing you on.
- Collect cores, build a streak, push your multiplier to ×3; chambers cleared with at most one ping and no damage earn a bonus.
- Fair darkness: a proximity sensor warns you with sound, vibration and visual cues. Fully playable with sound off.
- Daily Dive: today everyone dives into the same dark.
- Relaxed Dive: no collapse, 5 hull points, longer echoes.
- Share your record as a sonar map card.
- Even better with headphones, but not required.
- High contrast and large gauges keep everything clear in the dark.
