Why It Rocks

 * 1) The loop of this game can be beaten in 8 stages.
 * 2) Player 1 maneuvers Judge Spear and Player 2 maneuvers Blue Javelin to dodge and destroy enemy bots, structures, ground targets, and aircraft.
 * 3) Easy-to-us controls.
 * 4) Cool graphics.
 * 5) Nice gameplay.
 * 6) Awesome music.
 * 7) Well-heard sound effects.
 * 8) There are version differences in this game.
 * 9) *Secondary Weapons Systems: The original version of Viper Phase 1 has an exhaustible secondary weapon system. The amount of ammunition remaining in a secondary weapon is indicated by a meter on the screen. All secondary weapons in the original version are fully powered up, and are more devastating than in the new version, which gives the secondary weapons levels of power in lieu of unlimited ammunition and reduced firepower.
 * 10) *Bomb Deploy Times: The new version speeds up the deploy time of the bomb, which becomes the standard for when the ship appears in the Raiden Fighters series.
 * 11) *Medals: In the new version, medals stop shimmering for a brief moment, during which their point values are higher than usual. This feature is also present in Raiden DX. Additionally, the egg-shaped medal carrier pods appear much more frequently in the new version.
 * 12) There are 6 types of power ups in this game. They are released by destroying certain enemies. Players start with a primary vulcan cannon on each new life.
 * 13) *P (Power Up)
 * 14) **Original version: Powers up the main vulcan gun only.
 * 15) **New version: Powers up the vulcan (if the player is without secondary weapons) and the active secondary weapons (up to four levels).
 * 16) *B (Bomb): Adds one extra bomb. Players can carry up to seven bombs in stock. Extraneous pickups of the bomb icon awards the player 1,000 bonus points.
 * 17) *L (Laser):  This weapon is similar to the blue laser weapon in the original Raiden series. The weapon has no defensive spread. However, the laser is the most damaging secondary weapon available. It can make short work of large enemies and bosses. Ship's weapon module flashes blue.
 * 18) *M (Burst Missile):  Cruise missiles that are fired in a burst pattern. When the missiles hit their mark, the resulting explosion deals overlapping secondary damage. Ship's weapon module flashes yellow.
 * 19) *N (Napalm Missile):  Upon impact with an enemy target, this secondary weapon releases green napalm explosions in various directions. These explosions deal overlapping secondary damage. When fully powered-up, the cluster of explosions cover a substantial part of the screen, and may obscure enemy firepower. This weapon was included in the Raiden Fighters series as a cameo along with the ship (later named Judge Spear). Ship's module flashes green.
 * 20) *W (Wide Vulcan):  Grants the player a secondary widespread vulcan cannon. The spread of this weapon is useful in destroying enemies in many locations at once. The firepower, however, is the weakest of the four secondary weapons. Using this weapon at point-blank range on one enemy can deal moderate damage. Ship's module flashes red.
 * 21) Great boss fights.
 * 22) In the plot, it has two alternate endings after finishing the stage 8 boss. If you completely destroyed the missile, you get the good ending. But if you did not destroy the missile in a couple of seconds, you will get the bad ending.
 * 23) Challenging difficulties.
 * 24) Cool visual effects like real explosions.
