Batsugun is a vertically scrolling shoot 'em up video game created by the now-defunct Japanese game developer Toaplan. The title translates to "exceptional" or "extraordinary". It was the final game created before Toaplan's dissolution, and has been regarded as a key title in the development of the modern manic shooter, with elements of the game such as the size of the player's hitbox, the scale of their firepower, and the complexity of enemy bullet patterns all having an influence on future titles in the sub-genre. Members of the development team also went on to work on other successful manic shooters, most notably lead artist Junya Inoue.

In Gain Ground, players control one of a set of characters at a time. There are twenty characters, each with different weapons. To beat a level, players must reach the exit point with at least one character or destroy all enemies on the level before time runs out. Littered across the level are captive characters, which can be rescued by walking over, then escorting the controlled character to the exit point. If a player controlled character is killed, that character turns into a captive, except that they will disappear if the next active player controlled character dies, exits the level without them, or the player has no characters left in their party. The game is over when all controlled characters in the party are killed without any reaching the exit. However, there are three continues which allow a player to restart the level with their original three characters. There are 40 levels in the arcade version of the game. The Master System and the Genesis/Mega Drive have 50 levels in the game.

Soldiers of Fortune (Chaos Engine in the EU) is a run-and-gun overhead shooter. Sixteen levels (in four groups of four) await the players in the game. The basic gameplay is in an open air setting, with bridges across rivers and other features in the maps. The visuals are in a 'metallic and blue' style. There are six characters available in the game, each with different strengths and weaknesses, and different starting prices.

Terra Cresta is a vertically scrolling shoot 'em up. The player controls a ship, initially with limited firepower. Numbered pods appear containing further parts of the ship that will increase firepower. These additional parts combine with the player's ship to increase its firepower, and the final module transforms it into a fiery phoenix which is invulnerable for a certain period of time. Once the ship has multiple sections, the player may also split it, allowing it to fire in multiple directions. The player begins with three lives and it is possible to play with either one or two players.

Shooter / Arcade / Fantasy / Science fiction
Players attempt to shoot demons in a "cosmic carnival" and then pick up the diamonds left behind by them, while dodging shots from enemy skulls. The player operates a laser base at the bottom of a multi-row playfield, using the paddle controller to move it from side to side and the controller's action button to fire a laser beam vertically up the playfield. The player can control how far onto the playfield the beam advances by releasing the button at the desired height. The player receives one point for each demon and ten points for each diamond successfully shot. Points are multiplied by the distance from the base to the target. For example, a demon shot one row above the player is worth one point, while a demon shot four rows above the player is worth four points. In multiplayer mode, the second player operates a laser base at the top of the screen, firing from top to bottom. Again, the second player must shoot demons that match the color of its gun in order to produce diamonds. However, diamonds may be shot by either player. Also, skulls are capable of shooting both up and down the playfield. In select variations of the game, the players can shoot their opponent's laser gun in order to deplete their stock of extra lives. In both single and multiplayer versions, players begin with five lives. One life is lost when the player's laser base is hit by a laser beam fired by a skull or by an opponent, depending on the game variation being played. The game ends when all lives are lost; in multiplayer versions, the surviving player receives a bonus for each life remaining.
