Ryu Jin1993

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.

DonPachi is a 1995 vertical manic shoot-'em-up originally in arcades and was the first game from the developer Cave. Settings are mainly woodland and enemies are military vehicles and robots, culminating in the final boss, a huge robotic bee. One of three weapon configurations is chosen at start and then leveled up through dropped power-ups. DonPachi was ported to the Sega Saturn and Sony Playstation in 1996.

The fourth game in the Donpachi series.

Unlike in most other shoot 'em ups, there are no power-ups. All weapons are available from the start. Weapons can 'level up', however, becoming more powerful as the player uses them to score points. There are a selection of 7 weapons that can be used at any given time: The game is designed so that there is almost always a 'right' weapon for any situation. The bosses in the game are designed so that they have multiple 'sections' which, if all destroyed before the 'core' of the boss, will award the players with point bonuses. Being able to apply the right weapons on any different boss is key to obtaining these bonuses. For example, a boss may have two sections located on either side of the screen. You could immediately go up to one and begin shooting it with a vulcan, or you could hover in the centre and hit both at the same time with the side bombs. This would increase your chance of obtaining the bonus before the time limit runs out and the boss self-destructs. The game rewards players for "chaining" enemies of just one of three colors, red, blue, or yellow. Whenever the player kills three enemies that are of the same color, who can obtain a points bonus. This also facilitates faster upgrading of weapons.
