An excellent arcade-style shooter, Caverns of Mars is a downward-scrolling game where players must pilot their craft through a series of five underground levels filled with alien ships, narrow passageways and a variety of obstacles, including blue diamonds, force field barriers and floating space mines. Fuel must be collected along the way, and at the bottom of the last level a Martian base must be destroyed. Horizontal sections provide variety, scrolling is smooth, and the fast paced, though methodical shooting action is intensely enjoyable, making this a truly addictive game.
As a warrior of the Dimension X you are descended on Jaraloba planet to defend it from Rigillians. The planet is divided in 25 sectors (5x5 matrix), and each of them is filled with enemy forces. Controlling a ground skimmer, you should eliminate enemies in each sector and proceed through one of eight gates in surrounding mountains to another sector.
Sitting in cockpit of your skimmer, you may examine the view in first-person perspective, accelerate, decelerate your skimmer, turn left or right, and shoot the enemy vehicles. During your mission, radar helps you to detect the enemies out of your view, but fuel is exhausting, and shields are decreasing with enemy shots.
You and your adversary are in a wild west town at the time of the gold rush. Gold bars wild randomly spawn on the screen. It is your task to collect the bars and bring them to the assay office. The assay office in turn converts gold bars into money which you have to deposit in your bank. Each player has his own bank in town, so it's a matter of who will get the money to his bank first. After having collected ten bundles of dough you earn a house and heaps of bonus points. You can shoot the other cowboy who wil be hospitalized for a few seconds, giving you the opportunity to collect some gold/money in the meantime. The two cowboys are also followed by snakes and tumbleweeds respectively. However, snakes only go after one of the two cowboys while the tumbleweeds follow the other one. After being touched by the snakes/tumbledweeds the cowboy will be paralyzed for a few seconds. Shooting a snake turns it into a tumbleweed (and vice versa) therefore enabling the player to raise the number of enemies for his opponent.
