The game begins by asking the player(s) to choose a difficulty level, not only making the enemies more difficult and the players weaker, but higher difficulties start the players in a later set of levels (called "galaxies") and with some powerups. The easiest difficulty level starts the player(s) in the first level with no bonuses. The player controls a tank with constantly draining fuel, and must navigate through multiple levels (14 stations in the arcade version) from bottom to top, encountering obstacles and enemies. Along the way, a player may find powerups including tank fuel, stars (currency), shields, and two types of sub-weapons: smart shots (homing missiles) and bombs (powerful rockets). Each level has a key that will open a door at the top of the level, which will either take the player to the next level or to a special hub with multiple powerups that must be escaped in 10 seconds or less. If the player is unable to escape, the tank will lose half its fuel. After escaping the hub, the player(s) then proceeds to the next station. Occasionally, the player(s) will face a boss that must be defeated to advance. Normal shots are ineffective however, and the player must decide/guess the appropriate time to buy sub-weapons to greatly raise the chance of victory. After destroying a boss, the player(s) can continue to the end of the level. Between levels, the player is taken to a shop where items and upgrades to tank speed, power, etc. may be purchased with stars. Any damage caused to the player's tank will decrease the shield level. Purchasing a shield drastically reduces damage down to a mere pixel worth of the fuel gauge per hit. When the fuel depletes, the speed of the tank is reduced to a crawl and a countdown begins from 10. If no fuel is gained before the timer reaches zero, or if the player is shot during the countdown, the tank explodes and a life is lost. The arcade version, in addition to having special two-joystick controls for each player, contained three special contest levels, with one contest star in each. With three contest stars and nine normal stars, the player(s) could compete in a special time-limited contest level in which the player could win a T-shirt. A later version of the game was released which eliminated the contest levels and stars.

In this vertical scrolling spaceship shooter, you control a ship that can change its polarity at will. As blue/white, the ship can easily destroy red/black enemies, and vice versa. Bullets of your polarity can be collected to fuel your energy gauge, but those opposite will kill you. Destroying an enemy ship causes them to fire revenge bullets which can be absorbed and fired back by the player. Different difficulties exist to change exactly how you interact with polarized points, or how they appear. It is the spiritual successor to Radiant Silvergun, featuring similar level and boss design, as well as it's buddhism inspired themes and aesthetics. Both are directed by Hiroshi Iuchi, who also composed Ikaruga's soundtrack.

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.

The player controls a ship (bearing a resemblance to the Battlestar Galactica) which can fire and move left or right. The player must continuously monitor the onscreen temperature and fuel gauges; if the ship overheats, its weapon is disabled, and if it is depleted of fuel, the vessel itself explodes. The player must battle through waves of enemies, which attack with varied formations and flight patterns. When a wave is destroyed, a new one appears. At the end of each sector, the player flies through an asteroid belt and can obtain extra fuel by shooting fireballs. After this, the mother ship is met, where the player docks and refuels for the next sector. Also, the player is rewarded various bonuses for accomplishing certain feats, such as, shooting all enemies in a specific order or shooting all enemies without missing.
