"EL COCO" is an action-adventure game with a 3D isometric view. The player will move around the map with total freedom fighting against the nightmares (enemies) he finds and solving puzzles to advance through the labyrinthine paths of The Uncertain. The protagonist can absorb the weakened nightmares' abilities, giving him special powers useful in combat. His ultimate goal is to kill the 3 Supreme Nightmares that populate this place.
