Mega SWIV is a shoot-'em-up developed by Sales Curve Interactive in 1994 and published by Time Warner Interactive exclusively in Europe for the Sega Mega Drive. It is an extended port of the 1992 Super Nintendo game Super SWIV (also known as Firepower 2000) and the sequel to the original SWIV for home computers.

Definitions of the acronym "SWIV" have varied over time. In the original SWIV it stood for "Special Weapons Intercept Vehicles" or "Silkworm IV" (SWIV being a spiritual sequel to an earlier, side-scrolling shoot-'em-up, Silkworm (though Silkworm II and III do not exist)). It has also been dubbed by fans under the "Engrish" name, Silkworm In Vertical, though this loses much of its meaning when 1996's SWIV 3D comes into discussion.

Plot

Tests of prototype military airships near Bermuda end in disaster as the airships vanish; in reality, an underground race capture the airships and use their technology to build a new, unstoppable army powered by computer drones — an army that no nation's army can match. And it is up to the player to stop it.

Gameplay

B fires a single shot and can be held down for rapidfire. A cycles between a variety of weapons. C uses a special weapon that can be collected in levels. Weapons are powered up by collecting more from the same type. Each weapon has seven power levels. From the main menu, hitting A, B, or C allows access to a configuration menu which brings up the choice between playing as a helicopter (which will not be blocked by obstacles) or a tank (which can turn to aim in any direction but must actually complete the turn and stop firing before the gun sets in the new position).

The Jeep had the ability to jump in the original SNES release, a feature omitted from this version. Instead the jeep can no run over most obstacles that required a jump in the original.

Mega SWIV features an all new stage (stage 1, with the desert stage from the original becoming stage 2), not seen in any other iterations of the game.

Weapons

  • "Bullet" - default weapon, actually looks like rockets, gainst a small spread when powered up
  • "Flame" - Flamethrower
  • "Plasma" - up to 5 way blue spreadshot (almost identical to Twin Cobra)
  • "Laser" - piercing laser attack
  • "Ionic" - Split Shot (splits into two shots on contact)
  • Special Weapons: homing missiles, circular bomb, straight rockets
  • J Shot (counts as special weapon, last stage only, "J" likely stands for "Jedi", a reference to Star Wars)

Versions

Comparison with Super SWIV

It is widely thought that Mega SWIV was rushed to meet a deadline, as the game is not as fully optimised for Mega Drive hardware as seemingly planned.

Stage 3 (Jungle), for example loads a complete but largely unused 16-colour palette into memory, while pieces of scrap metal in the scenery appear to have been given the wrong palette line, causing them to appear dark grey with odd green spots. Assigning the unused palette to this metal causes it to look more natural, with a gradient metallic shading. Many design oversights, such as only a few flying enemies having shadows, also exist.

Also noticable is that enemy behaviours and sizes (e.g. the black jets) weren't recreated faithfully, causing Mega SWIV to become an easier game.
