Set in a World War II tank battle from a 1st-person perspective, the player can turn their tank left or right and fire their cannon. As they turn, enemy tanks appear, and they must be destroyed before the enemy tanks return fire.
As a deep sea diver, you sense an opportunity to gain untold wealth from the large number of treasures which have drifted to the bottom of the ocean. You do this by attaching yourself to your diving station and moving down the infested waters, grabbing an item of treasure and moving it back up to the station.
Various fish are around, including crabs, piranhas and squids, all of which move in their own ways, and can be shot with your gun. Worst of all are the sharks which can cut through your cord - make sure they do not swim above you close to the line. The cord can go through other fish safely and unimpeded, but contact with the fishes themselves costs you a life. You have 32 screens to plunder.
Space Armor is a 1984 shoot-'em-up game developed and published by Tsukuda Original. It was built with the Othello Multivision in mind, but like all Multivision games, is also compatible with the SG-1000. Space Armor was not released outside of Japan.
The game is built similarly to Namco's Xevious, in that it is a vertical shooter where one button fires at flying targets and the other at ground targets.
Ancipital is a typical Jeff Minter game with no storyline and an unusual setting. You play the role of what looks like a yak which can walk on two legs and shoots at enemies with bananas. At least in the first screen; the projectiles change in different levels. You can jump and flip upside down onto the ceiling to attack your foes.
The gameplay involves you shooting at enemies until the floor or walls change to let you move to the next screen which can be seen on the map in the corner of the screen. Each level has different themes ranging from skull and crossbones to cigarette papers and lighters.
The player must take control of Grobda, a tank trapped in an arena filled with numerous indestructible obstacles and several enemy tanks. When an enemy tank is killed, it will cause an explosion, and any other enemies that happen to be in the blast radius at the time will also suffer the same fate. But if Grobda is too close to the explosion, it will also be killed. Grobda has a shield that offers very temporary protection from enemy fire, but this will soon disappear if it is constantly under attack or shot. Each round is called a "battling", and there are a total of ninety-nine in the game.
This game is a port of the cancelled CBS Electronics' version of Targ with some minor changes.
Besides the different enemy graphics and slightly different sound effects, the screen changes color with each level. Also, most of the bugs present in Targ are absent, and the Spectar (called the 'Warlord’s shuttle' here – all the names have been changed) does appear.
Save the humanoids from the impending aliens in the sequel to Defender. The task is still rescuing humanoids before Landers can turn them into Mutants, while avoiding and shooting other foes, however you must now carry humanoids to safety through the Stargate of the title. Entering this Stargate not only warps you to the nearest humanoid in jeopardy, but can also warp you ahead (while on the first 15 levels) if you enter it with 4 or more humanoids, and give you extra lives if you warp with 10 humanoids, so there is a trade-off between guaranteeing the safety of existing humanoids, and trying to advance your position There are more enemies on screen than ever before. The Inviso button makes you invisible to enemies, but also to yourself, so you will have to follow your bullets to work out where on the screen you are.
I believe this is Compile's first vertically scrolling shooting game, and contains many elements they'd later incorporate into the Zanac / Aleste series. The title screen credits "Programmers-3" but I have seen re-releases crediting Compile. Plus, the sprite for the enemy that splits into two halves is exactly the same as the one in Zanac!
