Aquaventure

Aquaventure © 1983 Atari, Incorporated.

You must dive to the bottom of an undersea cavern and retrieve a fabulous treasure. Along the way you must avoid fish, sea horses, and other underwater creatures attempting to block your path. Your diver came prepared however, for he is armed with a spear gun which he can use to temporarily kill one of the creatures. However, each enemy you kill is soon replaced by a faster and indestructible version of itself, so you need to carefully carve a path to the bottom only destroying the creatures that get in your way. After retrieving the treasure and returning it to the top of the cavern, a mermaid will appear. Touching the mermaid will take you to the next level, where you get to do it all over again. At the top of the screen there is a turtle, which shows how much air you have left. If the turtle reaches the Air sign at the far end of the screen before you complete the level you lose a life.
