Most of the fundamentals of this game work in a similar way to Desert Strike. You pilot a helicopter or a three-barreled tank through 14 increasingly tough multi-phase missions, each of which is preceded by a full briefing and a shopping phase. Before each phase you can enter the shop and upgrade your weaponry, paying with golden medals gathered during previous phases. Your starting weapons are the chain gun and rockets/tank shells. Every weapon has three upgrade levels. After that, you can decide how much ammunition for each weapon you want to load into your vehicle's weapon bays, switch between the tank and the chopper (which can only be done between phases, and some of them don't give you the choice), choose one of the three special weapons and adjust the fuel/armor/speed characteristics. All these preparations are surprisingly complex for a shooter like this, and a bad configuration can make the game really hard (no fuel in the middle of the desert, or a paper-thin armor are just two examples). Missions are set in the desert and jungle as well as over the sea and in snowy regions. Most often your objectives are, obviously, to seek and destroy, while performing some rescue operations and gathering as much powerups as you can. The powerups consist of ammunition, fuel, medals, and others. A scanner is installed into the vehicle to guide you, as is a mapping system and a limited shield. Unusually, the game only scrolls vertically even though you have full directional movement. When you rotate the direction the ground moves underneath you, ensuring a more realistic effect and smartly mimicking motion effects.

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.

The game builds on the original Gradius by retaining the power-up bar system while introducing selectable weapon configurations and expanded abilities such as different missiles, double, and laser options. It also incorporates elements from Salamander (Life Force) and introduces a stage focused entirely on consecutive boss encounters.
