Hydra: Poseidon's Сonspiracy

You have been sent to the island of Kanaan to find an abandoned research facility of the "Third Reich". During the briefing, you received information that the facility was engaged in researching parallel dimensions and collecting information about ancient deities. There are various legends about the island of Kanaan, some say that it was once inhabited by a tribe worshiping ancient sea deities. Others claim that the control over the island belonged to the fish people. Four months earlier, tectonic tremors occurred throughout the archipelago, as a result of which tsunami waves rolled through the islands, but by some coincidence they missed Kanaan, but many of the buildings were damaged or collapsed.
