About
BLACKDEPTH is a third-person survival-horror game for iPhone.
The Helix Deep research facility went dark. Ash Calder is sent in. The only way out is down.
• 25 floors in five sectors: Intake, Research Wing, Bio-Containment, Reactor and The Root
• Five bosses, each with its own rules. Read the telegraphs, roll through the strike, punish the recovery
• Ten kinds of creature that behave differently: crawlers that pounce, armoured brutes you must flank, exploders that chain, shielded enforcers, regrowing lurkers and more
• Dodge-and-shoot combat designed for touch: floating stick, aim-assisted fire, roll with invincibility frames
• Five weapons you earn: service pistol, Breacher shotgun, Hornet SMG, Arc Rifle and Rail Lance
• Dr. Elena Kross's voice logs on every floor tell the story of Helix Deep, and what it was really built to hold back
• Endless Descent: an endless run on random floors with one life
• Workshop: earn Core Shards and upgrade your weapons, armour and medgels between runs
• Three difficulty levels. Easy is genuinely forgiving; Hard bites
Free to try: the whole first sector (floors 1 to 5). One purchase unlocks the full game. Works fully offline. No ads, no timers, no subscriptions.
Headphones recommended.
