## What is Sourcebound?

The screen is black, and the dark plays music.

Every footstep, every sonar pulse, every click of a hunter is a note, in tune and in time with the score, and each one sends out a wave that paints the walls in neon before the dark takes them back. Move quietly and you see almost nothing. Make noise and everything down here hears you.

Sourcebound is a top-down stealth game played by ear. Best played with headphones.

MUSIC PLAYED BY THE DARK
The soundtrack is composed live and follows your run: calm while you explore, tighter when they find you. Every sound of the level is part of it, played by an orchestra whose instruments follow the music: strings and horns, saws and acid bass, organ and bells. Every two levels a new ambiance brings its own ensemble. Open the studio to listen to it.

WHAT HUNTS YOU
Blind things that click in red. They wander, they turn toward every noise, they come to look, and when they are close they chase. Deeper down you meet the sentinel that chants where it stands and howls to call the others, the tracker that follows your footprints, the prowler that makes no sound at all and only your sonar reveals, a guardian posted at the exit, and a colossus whose wave sweeps the whole level.

LISTEN
• Your sonar reveals everything around you, and every hunter hears it
• Sprint to break away, but sprinting is loud
• Sneak to go silent, at the price of being nearly blind
• Throw a pebble to send them looking somewhere else

DESCEND
Collect the golden shards to unseal the exit, then go one level deeper. The levels are generated fresh every run, and no descent goes the same way twice. Twenty levels down lies the Source of silence. Reach it, or keep going into the endless dark.

FREE AND FULL
The first eight levels are free. The full version opens the descent all the way to the Source, the endless mode, the daily challenge, every level of Resonances, and the studio to compose your own ambiance. One purchase, no subscription.

GROW STRONGER
Every shard you collect is banked forever. Spend it on Resonances: permanent upgrades to your breath, your reach, your memory of the walls, your quiet steps. Each descent also offers a Relic: a single gift that lasts until you die.

ALSO
• Made for headphones: every creature is placed by ear
• Eleven music ambiances, from Orchestral and Electro to Dub, Cathedral, Clockwork and Ritual
• Ten strata down to the Source, each with its own look and music: nine visual themes (Neon, Lidar, Chalk, Cyanotype, Segments, Vector, Lidar 3D, Dungeon, Cave)
• Full touch controls, designed for iPhone and iPad
• English and French

Every level and every bar of music in this game is generated as you play.
