Eclipse is a third-person tactical and puzzle based game where throwing things is fun. Think Move, Observe, Throw. The player must successfully move about, dodging attacks and avoiding enemies. The player must observe the surroundings, seeing what can be interacted with and then decide the best possible plan of action.
The protagonist, Violet, has the mental capability to pick up objects from a distance and throw them at any target. Eclipse takes full advantage of the source engine by incorporating physics puzzles and destructible environments into its gameplay.
Two of the four levels in the Eclipse game demo are briefly shown in the demo reel. The first is Auld-Haven, where our protagonist, Violet, grew up. The other is the Dark Forest, where most of the action in the game demo takes place. The demo reel also shows the gameplay of Eclipse Move, Observe, Throw.
