Ninjas were everywhere in the 80s, and Japanese game developers were happy to fulfil the international demand for martial arts action. Nintendo’s console had Kung Fu, Ninja Gaiden, Ninja Turtles, The Legend of Kage, Shadow of the Ninja and many others. Sega had their Shinobi and Dragon Wang series, as well as their shortlived Ninja series.

Much like the Dragon Wang/Makai Retsuden series, Sega’s Ninja series is a somewhat convoluted progression of the same basic game template over a couple of generations of hardware.

Ninja Princess/Sega Ninja – Arcade

Ninja Princess (released in the west as Sega Ninja) began as a Sega System 1 arcade game in 1985. It’s an overhead run-and-gun game, one of a batch released around that time, such as Capcom’s Commando and SNK’s Ikari Warriors. Swapping out a warzone and slow moving bullets for Sengoku-era Japan and throwing knives, Ninja Princess is one of the first ever examples of an action game with a female protagonist, a whole year before the highly celebrated Metroid.

The game stars titular princess Kurumi, whose castle has been overrun by bad guys. She escapes a kidnap attempt in a cute animated intro, and sets out to take back the castle with her ninja skills.

It’s a truly great example of the genre, with tight gameplay, great graphics and sounds, and some nice gimmicks. You have two fire buttons – one fires knives (or via a power-up, ninja stars) in the direction you are facing, and the other always fires directly up, no matter which way you are oriented. This innovation completely fixes the clunky feeling the genre can have, as you can actually fire at enemies while retreating. The third button activates a temporary ninja-vanish to evade enemy attacks.

On top of this, Ninja Princess mixes up the gameplay with gimmick/event stages, including a stage where you avoid falling boulders, another with stampeding horses, one set on logs floating on a river, and two stages where you climb castle walls.

The graphics are fantastic, especially for 1985, colourful, detailed and stylish, and Kurumi herself is a particularly cute and nicely designed sprite.

The original arcade version is available on the Saturn, included in the compilation package Sega Ages Memorial Selection Volume 2.

It has a slightly squashed aspect ratio to fit in the Saturn’s resolution (but with no detail loss), and the graphics have been slightly retouched, mostly for the better. But it is a great way to play the game. One of the menu options allows you to play with infinite lives, which is a godsend, as being an 80s arcade game, it’s brutally difficult in the later stages.

Ninja Princess (忍者プリンセス) – SG1000

Sega’s first contemporary home port was for the SG1000 in 1986. As you’d expect, the graphics have taken a fairly big hit, and with only two buttons the ‘ninja vanish’ function has been mapped to hitting both action buttons at once, but it’s otherwise as faithful a port as could really be possible on the hardware.

The event stages are gone, but otherwise pretty much the entire game is intact, including the climbing stages. It’s actually quite fun to see some of the set-pieces from the arcade re-created in a more primitive form, and while the enemy ninjas are mostly single colour sprites in this version, their single colour often matches the primary colour of that enemy type in the arcade – you can see the designers of the port really tried to make it resemble the original.

The dinky SG1000 graphics have their own charm, and assuming you’re using a decent controller it plays really well for an SG1000 game. In an attempt to prolong the life of the title for home gamers, it introduces a ‘secret scroll’ system, and you have to collect all the secret scrolls to access the last level. They’re basically randomly located in the levels, so this is probably the most frustrating part.

While it had no chance of living up to the arcade original, it’s still very fun, and is one of the best games for the SG1000.

Ninja Princess 1 Mega Han (忍者プリンセス１メガ版) – Mark III

When Ninja Princess finally made it to hardware that could do it full justice – in the form of Sega’s newer Mark III console – it was ostensibly in the form of a sequel. Ninja Princess 1 Mega Han.

In what was assumedly an attempt to make the game more ‘serious’ (and perhaps appeal to console gaming’s primarily young male audience), the graphical style has been changed completely, removing any hint of the original game’s cutesyness. And instead of starring Kurumi the Ninja Princess, it stars a goofy looking dude named Kazamaru, who now must save the princess.

Despite the long-winded title on the box, the title screen shows simply ‘The Ninja’.

It’s set up as a sequel story-wise, but is actually another, more faithful, port of the arcade game. All the arcade event stages are back (in re-drawn form), including the falling boulders, stampeding horses, and river. Controls are identical and the scroll system is back from Ninja Princess SG1000, so you have to collect all five scrolls, then perform a particular task at a particular place to access the secret basement level and rescue the princess. There is also a new speed power up scroll.

It plays about as well as the arcade, but the new graphics are kind of badly drawn (especially the main sprites, including Kazamaru who looks as awkward in-game as he does on the cover), and the limited cartridge space meant there is much less detail and animation than the arcade game. Apart from the odd nicely drawn section, it’s not a particularly good looking Mark III game. There are more musical tracks, but they’re pretty bland, especially when your knives are powered up to ninja stars and you hear the same tune over and over.

The Ninja – Master System

Ninja Princess 1 Mega Han was released in the west under its title screen name The Ninja. While many Mark III/Master System games contain a universal ROM with both English and Japanese versions of the game onboard, The Ninja was actually ‘upgraded’ for its release outside of Japan. The western release gets a scrolling text intro, a new title screen, and an extra image on the splash screen when you collect all the scrolls.

Unfortunately the entire second level is missing, no doubt sacrificed to make space for the above. Which is a shame because it’s actually one of the better looking levels. Two of the secret scrolls have also changed location, one in particular makes a heck of a lot more sense in its Mark III location.

And here the Ninja series ended. One fantastic arcade game, a very good SG1000 game, and a decent-but-nothing-special Mark III game. They’re worth a play through, but probably the best experience of the series is to be had on the Saturn port of the arcade game.
