Radiant Silvergun (JP:レイディアント シルバーガン) is the first shooting game developed by Treasure in the year 1998. It is a vertical shooting game. The game features a futuristic, apocalyptic setting, and a single playable ship, the Silvergun. Somewhat unique for the genre, Radiant Silvergun features no traditional collectible power-ups, instead relying on score pertaining to one of the game's weapons to measure their power and effective range. The scoring mechanic involves chaining enemies of certain specific colors, Red, Blue and Green, with each chain of 3 increasing score progressively. Shooting an enemy of another color breaks the chain and its bonus points.
Radiant Silvergun was initially developed for the Sega Saturn adjacent arcade board ST-V, before being released to the home console Sega Saturn. It later received ports to the XBOX 360, Nintendo Switch and Windows PC. It has a spiritual sequel also developed by Treasure, named Ikaruga, featuring radically different gameplay mechanics.

Story
Radiant Silvergun's story is told in a non-linear fashion. Much of the dialogue between the characters and the special cutscenes, including opening and ending FMVs, are missing from the ST-V release of the game, only present in home console versions.
The ST-V board version/arcade version of home versions of Radiant Silvergun contains images with captions explaining the story of the game:
Nearby, a stone-like object is unearthed, but its purpose cannot be determined from analysis of its composition.
The Research Laboratory of the Global Coalition Forces successfully restores the Robonoid's memory data, but it is lost in a mysterious explosion.
At the same time, an unknown flying object and a stone-like object appear and begin an indiscriminate attack on the human race. Before long, the stone-like object emits a blinding light that annihilates the human race.
One year later... four crew members and a robonoid from the cruise ship Tetra who escaped death by taking in an orbiting satellite stake their survival on a mission to return to Earth.
Gameplay Overview
Radiant Silvergun is a 3-button game, featuring 8-directional movement. Pressing various buttons in tandem will deploy combined weapons. The game has 6 stages which the player tackles in non-linear order, starting with Stage 3 and ending with Stage 1, with most of them further divided into various substages, such as Stage 3B or Stage 5A. Each stage subdivision serves as natural breaking points for chains, and can be known as such by the appearance of the boss tally screen. The ST-V version/Arcade Mode of home ports lets the player access 5 of the six stages of the game, presenting a choice between Stage 2 and Stage 4 at the end of Stage 3, the game's first stage. The Saturn Mode/ Story Mode takes the player through all stages in the game, starting with Stage 3, Stage 2, Stage 4, Stage 5, Stage 6 and ending with Stage 1. The Saturn Mode/Story Mode allows the player to save their ship's progress after game over, letting the player carry on their power-ups to a new attempt.
Controls
|| 
|| 
- Directional buttons: Move the ship in eight directions. The player cannot influence ship speed in-game.
- A Button: Weapon Type A, Vulcan Laser.
- A (press): Fires a single red forward shot of Weapon Type A. Good for focused shots.
- A (hold): Fires multiples of two red twin shots of Weapon Type A. The higher the weapon's level, the higher the count of shots deployed by volley in multiples of 2.
- B Button: Weapon Type B, Homing Shot. Fires two green homing shots. The homing shots disappear after hitting walls and objects. The higher the weapon's level, the shots become bigger and inflict more damage.
- C Button: Weapon Type C, Spread Shot. Fires two blue spread shots in a diagonal angle forward. In contact with enemies, walls and objects, they will explode, forming a damage spread. They can be manually detonated as well. The higher the weapon level, the bigger the damage and the radius of the spread shot explosion.
- C (release): Manually detonates Weapon Type C shots. Only three pairs of spread shot can exist in the screen at a time.
In addition to the main Weapon types, Radiant Silvergun also features four different attacks that can be performed by pressing two buttons in tandem (in home console releases, these attack combinations can be bound to other buttons as well). These weapons' firepower and range are associated to their founding Weapon Types:
|| 
|| 
- A Button + B Button: Weapon Type A+B, Homing Plasma. Seeks an enemy/object to target within its line of fire (roughly ~90 variable degrees in front of the ship) and fires a homing plasma lightning shot at it. The shot increases in size and damage as time passes touching the same target. Moving away of the initial locked angle will free the weapon and end the damage on target. Can pass through walls. Its damage and angular radius increase with the Weapon Type increases of A and B.
- A Button + C Button: Weapon Type A+C, Back-Wide Shot. Fires a back volley of shots as well as a forward single shot volley. Its damage and amount of back fires shot increase with the Weapon Type increases of A and C.
- B Button + C Button: Weapon Type B+C, Lock-On Spread. Fires explosive bullets at all targets within weapon's radius. These shots take a while to reach their target location (which may not be the same location as the enemy if it is mobile) and explode in a radius. Can pass through walls and enemies. This is the only weapon that can uncover the game's secret hidden dogs called Merry. Its firing frequency and damage increase with the Weapon Type increases of B and C.
- A Button + B Button + C Button: Weapon Type A+B+C, Radiant Sword. Combining all three weapon types lets the player utilize the Radiant Sword. Its initial swipe is determined by the last directional movement inputted by the player. The blade remains targetting the opposite of the last inputted direction (for example, if the player is moving forward, the sword will face backwards). Inflicts continuous damage to targets in contact. Can absorb pink bullets fired by enemies, filling the Hyper Sword Gauge. Its damage increases with the Weapon Type increases of A, B and C.
- A+B+C (Full Gauge):' Weapon Type A+B+C, Hyper Sword. By pressing the Radiant Sword button when the Hyper Sword Gauge is full (10 pink bullets are enough to fill the gauge), the ship can perform Hyper Sword. Two big blades point towards the forward diagonals, go back and lunge forward, crashing at each other. These blades inflict contact damage to enemies. After crashing at each other, the swords spread shrapnels, which can also damage enemies. While using this attack, the Silvergun is temporarily immune to all contact damage, including that of walls and environmental hazards, serving as this game's version of the Bomb. Its damage increases with the Weapon Type increases of A, B and C. If the player loses a life, the Hyper Sword Gauge resets to default value.
Extends
The player starts with 3 ships by default (2 in stock, 1 in use).Extra ships can be acquired by default on ST-V version in the score thresholds of 1,000,000 points and 5,000,000 points. The player can change the default Extend values in-game before starting a session on the home console realeases. The player can also change the number of starting ships in Options before starting a session in the home console releases, though it depends on the chosen mode of the game.
Difficulty Modes
The ST-V version of the game runs on Normal difficulty. The home console releases of the game have 5 different difficulty settings: Very Easy, Easy, Normal, Hard and Very Hard. Very Easy and Easy feature less enemies, meaning that chain routes differ meaningfully from other versions. Hard and Very Hard modes add revenge bullets to some and most enemies, respectively. The chosen difficulty mode will also alter boss behaviour: most notably, Stage 3D boss arena's pillars vary greatly between difficulty modes: they will spin around on higher difficulties (Hard and Very Hard), destroying the player ship on contact, while in lower difficulties they come in smaller numbers.
Stages
WIP Radiant Silvergun presents a total of 6 stages, each divided into sub-sections discriminated by letters (e.g. 3C, 5A). Your chain does not carry over on each sub-section of a stage, and you can determine a stage has ended when you see the boss tally screen at the end of the every boss fight, followed by the new stage screen, listing the sub-section and current time of events.
Bosses
WIP Radiant Silvergun features a total of 22 named bosses, all with distinct visuals and behaviours. As most bosses don't fight alongside enemies, your main ways of attaining points while fighting bosses consist of destroying individual bits of the boss itself, as well as Weapon Bonuses and grazing bonuses. If too much time is taken fighting the boss, it will self-destruct, awarding the player no points for its destruction.
Scoring Mechanics
WIP There are four ways to score in Radiant Silvergun: destroying enemies, fulfilling Weapon Bonus conditions, finding Merries scattered throughout the stages, and grazing. As weapon damage is tied to score, it is important not to ignore the score mechanics when playing the game, or some bosses will only ever be progressed through by waiting for their self-destruction, awarding the player no points. However, it is beneficial in high-level play to milk points whenever possible, including on bosses that do allow chain progression, such as 5A's SBS 130.
Secrets
Scattered through the game are small dogs known as "Merry". They can be found by using Weapon Type B+C on specific parts of the stages. They reward the player with bonus points and unlock bonus options (called "Option +" in the Sega Saturn home console release of the game.
Strategy
WIP Strategies between lower-level players and higher-level players seeking score differ considerably, but the general principles of chain progression, adequate routing and boss destruction also apply. Knowing how to use every different weapon to its full potential is key to meaningfully engage with the game's system and core gameplay loop.

Trivia
WIP
- The boss of Stage 3C, Gallop, resembles the playable ship from the R-Type series, the R9-A Arrowhead, and its iconic Bydo embryo appendage.
- The final boss of the game, Xiga, resembles the titular character of the japanese Tokusatsu series Ultraman, and its name "Xiga" may be a callback to Ultraman Tiga, one of the show's entries, released in 1996-1997, right around Radiant Silvergun's development time.
