Space Cavern

You are the commander of an intergalactic starship on a mission to explore new, strange planets. After landing on a new world and beginning to explore the numerous caverns, you discover the planet is inhabited by the deadly Electrosauri. These creatures can generate lethal electric charges, and are now after you! Using your laser gun, you need to defend yourself from the onslaught of Electrosauri. The deadly creatures can come from above, the left, or the right so be sure to keep an eye on all corners of the screen! There are numerous game variations included which dictate the number of attacking creatures that can appear at a time, their firing characteristics, and the overall difficulty level.

Each time you eliminate a large Electrosauri, you'll gain 115 points, whereas smaller ones hold a value of 165 points. The fast-moving marsupods emerging from caves on both the left and right will grant you 200 points.
