Hostile Void
Read full descriptionHide full description
Light is all you have. Every step drains it. Every mistake costs you. Explore a vast, interconnected dungeon where survival depends on how you manage what little light remains. Search forgotten rooms, uncover hidden passages, collect supplies, and face creatures lurking in the darkness. Your lantern helps you survive — but its fuel is limited. Fighting consumes precious energy, and death carries consequences. Three interconnected zones. Dangerous encounters. Secrets waiting in the dark. How far can you make it into the void?

A maze with no light in it. You are the only light there is. Touch the screen and your voice goes out as a ring. Walls flare where it passes, then fade back into nothing. What you saw, you have to remember. The dark does not keep it for you. Take the Journey, level by level, or go down into Survival: an endless descent, one life, as deep as you dare. TWO VOICES, AND A PRICE A whisper is cheap and shows you almost nothing: a small circle of the world, close to you. A call carries across a room. It charges the resonators that open sealed doors, and it wakes whatever else is down here, listening. A hundred levels are built on that one choice: how much light is worth how much risk. TWELVE ACTS, DEEPENING The first ones teach you your own voice. Then something that sleeps in the dark learns it too. It cannot hear a whisper. A call, it hears. Later the world stops answering at all, and you cross whole rooms from memory while more than one thing follows the sound of you. FELT, NOT ONLY HEARD Every echo fans out under your palm through the Taptic Engine, in time with the sound. Nothing here is a recording. The soundscape is generated live: a calm pad breathing over near-silence, thinning as the dread rises to take its place. Headphones, if you have them. A dark room, if you can. WHAT IT COSTS Levels 1 to 20 are free. That is the whole hunt: both voices, sealed doors, zones of silence, and four acts spent beside things that come for the sound you make. One purchase opens the other eighty and everything in them: the pack that learns your habits, silence laid over whole maps, and the abyss, which is not the bottom. It opens Survival too, the endless descent. There is nothing else to buy, ever. No advertising. No subscription. No account of its own (Game Center is optional). The only permission the game asks for is an optional daily reminder for Survival. ACCESSIBILITY Reduce Motion, from iOS or from the game's own settings, stills the camera shake, the parallax and the pulsing. The echo itself stays: it is the game. Sound and haptics have their own separate controls, and the menus and in-game controls are labelled for VoiceOver. iPhone, held either way. Best alone. ECHO is made by Crowmill. More at crowmill.com.

Verdict
The clearest difference is in-app purchases: Hostile Void at none against ECHO's 1. ECHO's advantage is update cadence (every 2 days vs weekly). On price, ads, device support and iOS requirement there is nothing between them.
