In Caverns of Mars, the player descends into cave and at the end must retrace their steps back to the top. Christensen wrote two less successful follow-ups, one of which scrolls horizontally and is very similar to Scramble.
Gameplay
Caverns of Mars is a scrolling shooter similar in concept and visual style to the 1981 Konami arcade video game Scramble.[5] Christensen changed the orientation of the levels, having the player fly down into them as opposed to horizontally through them. Unlike Scramble, rockets in Caverns of Mars remain on the ground.
Using a joystick, the player controls a ship descending through a hole on the surface of Mars into a vertical tunnel. The player's spacecraft has two cannons, positioned on either side of the craft, firing downward. The player must avoid hitting the walls while shooting targets of opportunity along the way. Fuel tanks give 5 units of fuel when shot, and the craft is destroyed if it runs out.
The cavern is divided into different sections depending on the skill level: the easiest setting has three sections, the hardest has six. The final section is always a reactor which the player lands on and sets to explode. The ship then reverses course and has to fly up and out of the caverns to escape before the detonation occurs.
Development
Greg Christensen, a high-school senior, purchased an Atari 800 in 1981 and created Caverns in "little more than a month and a half"[6] using the Atari Assembler Editor.[7] It was the first significant program he wrote in 6502 assembly language.[6] Fred Thorlin of Atari Program Exchange recalled Caverns arriving at APX:
It was received by APX in the morning mail. I saw it at 10:30. We showed it to the president of the company just after lunch. It was not a tough decision for him. Legal got in touch with Greg Christensen in short order. The young man, I think he was a community college freshman, suddenly had a bunch of money inflicted upon him. I was never certain whether he benefited from that in the long run or not.[8]
In the original version, when the player reaches the end of the selected map, the game ends. Thorlin felt it needed something more. Christensen was too busy, but agreed to use his royalties to pay for someone else to do the work. Thorlin hired Richard Watts of Macrotronics to make a number of modifications. This included a new ending in which the player has to fly back out of the cavern in reverse before a timer runs out.[9]
Two months after sending it to APX, Christensen received his first royalty check for $18,000 and a phone call from an Atari executive who praised the game. Caverns eventually won the 1981 APX game contest, winning another $3,000, and in December 1982, Atari told Christensen he might receive up to $100,000 in royalties.[10]
Atari licensed the game in early 1982 for distribution in the main Atari catalog on
Reception
Caverns of Mars received a Certificate of Merit in the category of "Best Science Fiction/Fantasy Computer Game" at the 4th annual
Legacy
Mars Mission II
Christensen followed Caverns with a lesser-known sequel, originally titled Caverns of Mars II. It is very similar to Scramble, scrolling horizontally and with rockets that launch upward from the ground. The game was completed in 1981, but not published until several years later by Antic Software as Mars Mission II.[19]
Phobos
Phobos keeps the vertical orientation of the original with improved graphics and more sections in each cavern.[20] The caverns are narrower and more difficult to maneuver in right from the start. It was released through the Atari Program Exchange in 1982, then later Antic Software.
Softline stated that Phobos might disappoint Caverns of Mars players, stating that it was "a reinvention of the wheel" and too easy for them. The magazine noted some improvements, such as a
Re-release and remake
In 2005, a version of Caverns of Mars was included on the
In 2023, the game is set for a March release for Microsoft Windows, Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One and Xbox Series X/S, under the title Caverns of Mars: Recharged.[23]
Clones
Datamost's Cavern Creatures (1983) for the Apple II is very similar.[24] Conquest of Mars (2006) for the Atari 2600 is a direct clone.
