Le Trésor Englouti +

Le Trésor Englouti + is an underwater treasure hunting game. The player controls a diver who has to enter three caves searching for the treasure. The only open cave in the beginning of the game is the one in the bottom left side of the screen. To reach it, the player has to avoid the fish in the sea as touching them make the diver lose oxygen. When the player reaches the cave, the screen changes and the interior of the cave is shown.

The cave is maze shaped and has six chests in it. One of the chests is empty, two of them holds sea animals: one holds a crab, one holds an octopus. Once they're free, they'll move about the cave, if they touch the diver, he dies and the game is over. One chest holds a grenade, which can be used to kill the enemies if they pass by when it is placed. One of the chests holds the key to the second cave, and one last hides a trapdoor to exit the cave. While the diver searches for the treasure, he'll lose oxygen. His boat is waiting up outside with three extra oxygen tanks. If the player swims up to it, one can be grabbed by pressing the action button. It will be necessary, as navigating inside caves it is difficult, the player has to place the diver in the right position or else he will bump in the walls.

Once in possession of the key, the player has to move the diver to the next cave. The second cave has a different maze layout, but the gameplay inside it is the same as the first. Once the player reaches the third cave, things get more difficult, as the third cave is dark and only a short distance around the diver can be seen. The game is won when the diver finds the treasure and returns to the boat without getting asphyxiated.
