Hydra

Hydra is a detective game with survival horror elements. You play as Seth, sent to the island of Kanaan to find an abandoned research facility built by the “Third Reich.” The facility investigated parallel dimensions and gathered information about ancient deities. As you investigate, you uncover the island’s history and face creatures emerging from the ocean depths.

The island of Kanaan

Legends say the island was once home to a tribe that worshiped ancient sea deities; other accounts say it was controlled by fish people. Four months before Seth’s arrival, tectonic tremors struck the archipelago and tsunami waves swept through the islands. Kanaan was spared by the waves, but many of its buildings were damaged or collapsed.

You encounter characters who may offer useful information or treat Seth unfavorably. Investigation involves examining eerie clues and solving puzzles, while scavenging weapons, notes, food, medicine and utility items related to your task.

Seth’s condition

Seth’s health, endurance and sanity must be kept at a decent level. He can die from damage or fall into madness. Endurance determines how long he can run, parry blows and attack with melee weapons. A mental health system tracks his sanity as you endure the island’s horrors.

Two perspectives

You can switch between first-person and isometric perspectives at any time. In the isometric view, Seth fights at close range with melee weapons and can parry opponents’ attacks. First-person view shows the world through his eye implants: Seth lost his eyesight during a mission for the NML corporation, which supplied him with inexpensive implants so he could keep working. The implants provide night vision and environmental analysis, which can mark useful elements in the surroundings.

Endings and atmosphere

Your actions determine which of five endings you reach. Haunting soundscapes accompany the investigation and encounters, and the game combines retro and modern elements.
