Eresys is an online co-op/offline singleplayer horror game inspired by H.P Lovecraft which focuses mainly on teamwork. A party of 4 players face together the fears of the Lovecraftian Universe. Featuring smart AI mechanics with horrifying entities that will make you regret stepping into the forest.
Only by working together and using the order of the occult will you be able to stand a chance.

• Visuals - Immersive environment with delicate presentation of monsters and characters.

Story - After being expelled from the cult, a deranged former member has opened a Void Portal on a secluded island, unleashing horrific entities that have already claimed the lives of many. You and your fellow cultists must work together to send the entities back to where they came from and seal the portal to prevent further destruction. To accomplish this, you must locate and gather the resources needed to make offerings at the altars and perform the final ritual. Time is of the essence, can you and your team complete the task before the entities overrun the island and unleash their terror on the world beyond?

• Smart AI - Those entities are not your typical kind of “Monsters”. They will calculate all your choices and actions. This will also have an immediate impact on their AI and create new ways to devour you.

• Unexpected Events - It could be a small coin or an idol, anything that is linked to the occult that could trigger a surprising and unexpected event. You never know what is hiding behind each item.

• Safe Houses - Houses and other buildings can provide temporary safety. Hidden lootable items and resources can be found, which you will need to complete the final ritual.

• Caves - Caves can offer a brief respite from danger and a source of resources, but be wary - they may also conceal sinister surprises.

• The Book - Players must decide who carries the powerful tome, the book of the order, which can banish the ancient entity once it is complete.

• Pages - The book of the order has missing pages, to complete the final ritual, you will have to gather every missing page.

• Victims - The enchanted victims and other resources can be found around the island which was used by the cultist. You have to gather their blood and fill your vials with it.

• The Oil Lamps - The Entities have been in the void for eons and they are not familiar with the Light. Stick together with your teammates with at least 2 lamps lit. This will be one of the many ways to keep them at a distance. Remember that you will need oil to refill the lamps.

• Altars - Altars are a manifestation from the necroworld summoned by the expelled cultist. Offer them blood and they will reward you with blood spheres.
