Amstrad CPC[edit]

  • Stars with six extra lives. However, it is single-player.
  • Uses push scrolling.
  • Stage 2 has levels in a continuous run.
  • Stage 2 boss seems to lock the camera. It may not be safe attempting to attack the boss from underneath.
  • Stage 3 boss has four saws in the first stage
  • Stage 4 has all enemies attack from the right.
  • The boat in Stage 7 is visible on approach, and moves back and forth once you reach the front cannons.
  • Keys are disposed when entering Stage 8. You can still get all six keys from the left-most ladder.
  • The Final boss has only two phases.

Commodore 64[edit]

Ported by Ocean. Single player only, and one difficulty level.

While stages remain the same, some bosses have been reduced in power. The differences include:

  • Starting with four lives rather than 2.
  • Removal of the allied car in Stage 1.
  • Tank enemies, such as the boss in Stage 1, fire single shots.
  • Stage 2 uses a continuous level rather than having stage segments fly downward. The moving platforms are now stationary, share the same health pool, but have a gear moving from the side.
  • Stage 2 boss doesn't have a second stage that requires hitting a specific point
  • Stage 3 has one lift instead of four.
  • Saws in Stage 3 follow a different attack pattern. The second attack form has smaller and slower gears, and attack slowly.
  • Enemies attack from both directions in [[../Stage 4/], and there are only six attacking planes.
  • Stage 5 boss accelerates as it takes damage. It can also be insta-killed with the shotgun by jumping underneath it (after the electric barriers are destroyed), and shooting upward.
  • Gears in Stage 6 are smaller, and don't have epicyclic gears.
  • The boat in Stage 7 is visible on approach, and moves back and forth once you reach the front cannons. It also has fewer turrets.
  • The faces in Stage 9 attack individually rather than being in large groups. The final boss is also much smaller, and only has two attack phases.
  • Barrier isn't available in this version.
  • Homing only launches three shots.

Commodore Amiga[edit]

Ported by Ocean. Two players, and five continues are allowed among the two players, but include no means to adjust difficulty.

Major Differences include:

  • Tanks, such as the boss in Stage 1, have their bullets fire at variable speeds. In addition, they explode instantly, as with all other bosses in this port.
  • Stage 2 uses a continuous level rather than having stage segments fly downward. As such, the moving platforms are already blocking your path, and cannot be bypassed. However, the platforms all share the same health pool and are destroyed at the same time.
  • Stage 2 boss doesn't have a second stage that requires hitting a specific point
  • Stage 3 has faster perceived movements of the lifts.
  • Stage 3 boss has four saws. It's second form has its two saws moving slowly on top, before making a quick attack on the bottom. It's third form fires a volley of four shots instead of one.
  • Stage 4 has enemies attack from both directions.
  • The boat in Stage 7 is visible on approach, and moves back and forth once you reach the front cannons.
  • Take the third ladder in Stage 8 for all six keys.
  • The final boss only has two phases. The final attack phase is more resiliant to attack.

Sega Mega Drive[edit]

The story behind this version has changed slightly; the commando is known as Johnny Ford, and the antagonist is known as "The Crimson King". In this version, the antagonist kidnapped the commando's father because he invented a serum that negates drug addiction.
