Sightings from the Deep

The premise of the story, is that you live in a world dominated by monsters, who have been driving out humankind for years. Hunting parties were formed, in an attempt to cull the monster population, but it's becoming clear that the humans are losing this war. You play as one such hunter, that one day, during a hunting expedition, finds an unusual monster, with humanlike mannerisms, very different from the usual monsters. Not being able to kill it, you rescue the creature, and bring them to your abandoned base. The creature then proposes a pact to you. If you show her strong emotions from monsters of this world, she can be rid of the monster infestation for you.

Sightings from the Deep is an "On-Rails Photography game", inspired heavily by games such as Pokémon Snap, but set in a dying, Bloodborne-esque, horror setting.
