## What is Cthulhu?

You are the monster beneath the waves.

CTHULHU is a dark, hand-painted arcade game where humanity is the enemy and the ocean belongs to you. Rise from the abyss, smash ships with your tentacles, and dive before the depth charges find you. The longer you survive, the harder the world fights back - fishing boats give way to patrol boats, destroyers, submarines, minefields, and finally the entire navy.

FEATURES
- One-thumb movement, instant tentacle strikes, and devastating special powers: Abyssal Roar, Whirlpool, Ink Cloud, Tentacle Frenzy, Call of the Deep, and the Rage of Cthulhu
- An escalating endless run with three unique bosses: The Dreadnought, the Carrier Strike Group, and SSN Leviathan
- A combo system that rewards fearless aggression - chain kills to x50
- Grow stronger every run: earn Abyssal Essence and unlock 9 permanent upgrades and 6 attunable powers
- Nightly run modifiers that change the rules: minefields, swift fleets, rich waters and more
- 11 achievements, local records, and a Game Center leaderboard
- Entirely hand-painted moonlit art, procedural audio, full offline play

The deep is patient. The deep is hungry. One more run.
