There are 6 pilots in the game. Bomb type and weapon colour are changed depending on the pilot.
Weapon system Edit
A fighter can fire strong but concentrated shots, or weak but widespread shots, depending on the button pressed. The fighter's shot strength changes depending on how heavily it is pressed, with 3 pre-defined shot strength settings available in the game. The fighter's moving speed decreases with increasing shot strength, and decreases otherwise.
There are 8 stages in the game. In addition, there are 2 extra stages that can be unlocked when certain conditions are met. The game's ending is changed depending on the selected pilot.
Multiplier system Edit
When an enemy is destroyed, its score is multiplied between 1 and 256, depending on the frequency the fighter was firing at the time of destruction. Some enemies drop stars when destroyed by high power shots, and sometimes the enemy bullets are turned into stars. A star's multiplier is between 1 and 256 when the star is collected, but the multiplier value decreases when the fighter fires more heavily. Only when the fighter fires weak or no shots that the star's multiplier is at 256.
The game was released on the PlayStation 2 in Japan as Double Shienryu, the 37th entry in D3 Publisher's "Simple 2000" series and as the 5th entry in the "Simple 2000 2-in-1" with The Helicopter, while on Europe it was released as Steel Dragon EX, where Shienryu Explosion was renamed as Steel Dragon Evolution.
