Donkey Kong 3: Dai Gyakushū

Donkey Kong 3: Dai Gyakushū (ドンキーコング3 大逆襲) is a game developed by Hudson Soft in 1984. The game had versions for the NEC PC-6001mkII/NEC PC-6601, NEC PC-8801, and Sharp X1, all of which had differences between each other (palette and flow of gameplay, respectively). The same year, Hudson had released and would release Punch Ball Mario Bros. and Mario Bros. Special, respectively. This was the last Donkey Kong game until Donkey Kong on the Game Boy.

Unlike Punch Ball Mario Bros. and Mario Bros. Special, the game was not released on the FM-7 - a version was planned and possibly even completely programmed, but was canceled for unknown reasons.

The game was lost for many years, but the Sharp X1 version was found in December 2017 at an online auction.

Gameplay
Like Mario Bros. Special and Punch Ball Mario Bros., the game is not a port, but more of a semi-sequel to Donkey Kong 3. Stanley the Bugman's ability to jump is removed, along with the need to protect plants, making it much closer to a traditional shooter, à la Galaga.

Enemies come down from the top of the screen in groups of five, swooping to the bottom and trying to target Stanley. After swooping around a bit, the enemies will exit the screen (usually from the bottom, though sometimes from the sides) and loop back around to the top. This will continue until Stanley dies, shoots Donkey Kong to the top of the screen, thus completing it, or kills the five insects, all of which take two hits apiece to kill. If Stanley kills all five insects before any of them loop back to the top of the screen, a flag reminiscent of one from Rally-X will appear, and shooting it will net him 1,000 points.

There are twenty new stages, looping back at Stage 21. Every five stages a Bonus Stage comes up, where Stanley must spray all the bugs before the time runs out. The game sees him chase Donkey Kong into the countryside, through space, and eventually into a city on an alien planet, with no conclusion to the story.

A highway at sunset, with mountains in the distance.

A very long highway bridge, sunset is still visible.

Stage 4: The Aliens
A blank, tan background with green and black aliens that seem to be coming towards Donkey Kong and Stanley.

Stage 5: In the U.F.O.
Seems to take place inside a UFO. Presumably, the aliens from Stage 4 have kidnapped Donkey Kong and Stanley, however the battle between the two continues to play out.

Appears to take place in space with Earth in the background, presumably inside the UFO, though it is not visible here.

An asteroid belt appears in the background.

Stage 8: Around the Saturn
The planet Saturn appears in the background.

Stage 9: A Mysterious Planet
An unknown planet appears in the background.

Stage 10: On the Desert
On an unknown desert, with what seems to be the moon in the background. Presumably, Donkey Kong and Stanley, along with the aliens, have landed on the mysterious planet shown in Stage 9.

A long pathway with swirling walls completely encircling it.

Stage 17: At the Runway

Stage 20: In the City
Takes place in the middle of a large city. Several buildings are shown in the background, as well as what seems to be lightning. Stars are also visible.
