Eleusis is a 3d first-person adventure game for Windows developed by Nocturnal Works using the technology of the unreal engine. It takes place in a seemingly abandoned village in Greece where the player character, while trying to seek refuge, finds himself in the center of a whirlwind of mysterious events.As the plot unfolds he finds clues that indicate that the village is a nest of a cult which plans to revive a dark force through an ancient ritual and harness its power. The player character faces the challenge of unlocking the forgotten knowledge of the ancient mysteries in order to stop the cult from accomplishing their goal.

It is an exploration based adventure game where the player is called to solve the mystery by finding clues and reading texts based on actual history, mythology and technology of ancient Greece.

Features

High detailed realistic graphics with Directx11 support.
Explore open environment with realistic physics in the Greek countryside.
Challenging item–based Puzzles with simple interface.
Dark atmosphere with eerie sounds.
Unique storyline.

I'm wondering why some games use the keyboard for movement. Don't they know most adventure gamers prefer using the mouse? To me, it's more hassle to use the keyboard. IMHO

This is the first of the two major planned updates. In this one all known gameplay bugs and issues have been fixed and more hints have been added to ensure a smooth gameplay for all players. See changelog for the full list.

The second planned update will add new horror elements to the game. We are currently working on adding an new threat to the player that will enhance the gameplay experience. Moreover, there will be optimization of the DX11 features and a bindable keys option will be added. We estimate this second update to be released next week so we suggest anyone who wants to enjoy the new features of the game to wait until then.

Also a Mac release is in our future plans.

The update is automatically done on Desura. Currently the game is only available on Desura so the people that purchased it have already the updated version.
