This game features multiple different gameplay elements. The battle system within the game not only has “experience points” but it gives “skill points” to characters so they can learn new abilities.
In the latter half of the game, there’s a lottery system that allows rare items, not found anywhere else in the game, to be obtained.
The appraisal system was one of the first alchemy-like interfaces in a game in the 20th century version of Evolution.
Dark Arms features a girl, Meghan Loughlin, whose job is to defeat and contain an outbreak of demons and act as a mediator between this world and the next.
The player can collect the spirits of the various demons and zombies they fight in the game with a gun known as “The Catcher”.
The player-character can then use captured spirits to ‘feed’ their weapons and evolve them into more powerful forms. For example, the Handgun evolves into the Sub Shotgun, which can evolve further into the Shotgun.
Biomotor Unitron is a “dungeon crawler” RPG with pseudorandom dungeons. The player controls a robot called a Unitron, and walks through the dungeons fighting battles to earn money and experience. The experience boosts stats for the player character, and their “control” of the Unitron, but not the Unitron itself. There is rather a system of parts upgrades. The upgraded parts can be purchased, or “developed” using existing items, “tools”, and “materials”.
The game has a fairly standard HP system. Instead of MP, there is EP, and EP is consumed with every action in battle. EP regenerates with every battle. In the game, there are initially four dungeons and a town. Each of the four dungeons that are initially available, has elemental affinity, and seven floors.
Each dungeon’s layout, rather than being truly random, is selected from multiple preprogrammed layouts. The town is menu-driven, with access to “Works”, where you equip parts, develop parts, and save data.
There is also a shop, and there are multiple areas you can visit to talk to the townspeople. Some of the townspeople provide stat boosts, or will sell items to you. Finally, there is an arena in town, where you can fight other Unitrons for money, prizes, and many levels of advancing rank. The game has two main goals.
The first goal is to build your Unitron up as much as possible. The second, is to clear the first four elemental affinity dungeons, and then clear the final dungeon, finishing the game.
The player takes control of a character named Matt. The game is set in the future and the world is primarily surrounded by water. There is a small patch of land called Terra. Terra is the only land.
The player must prove their worth to be accepted on to Terra. They do this by proving their skill as a submarine commander and destroying enemy vessels.
Matt’s version features different characters, items and boats to Becky’s version.
The battles take place against other ships. A radar view is used to help you guide torpedoes against the enemy. A large part of the game is text-based, with animated cutscenes.
Two players can link up their consoles with a link cable to battle and exchange ships.
