Apart from the hideous music, and monotonous blue-on-blue-on-black colour scheme, SDI is a little gem. It may not feature state-of-the-art 3D animated graphics, icon controls or all the other dooflippery, but it's a mega blast and you can't ask better than that, can you punters?
Atari STThe One
All in all SDI is quite definitely the most accurate coin-op conversion to date, and even pips Super Hang-On
when it comes down to sheer playability value. An absolute must for all ST owners.

Global Defense ist ein etwas anderer Shooter, der durch seine besondere Steuerung und den Koop-Multiplayer verdammt viel Spaß macht. Klare Kaufempfehlung für alle Freunde der gepflegten Ballerei!

Addictive, tough and packed full of features, SDI belies its coin-op origins by being very well paced to boot. One of the best coin-op conversions this year.

On a single One Mega Cartridge, Global Defense manages to put big name coin-op conversions like Afterburner on Two Mega cartridges to shame. A very close version indeed with some wonderful backdrops (getting even better on the later levels) which really show what the Sega is capable of when the programmers put their minds to it. Much of the coin-op's playability has been recaptured and each level is faithfully recreated both graphically and in general gameplay. Where the game loses out is in the sound (which is nothing special) and the lack of twin-player action. It's mystifying that Sega should have problems with converting dual player games. This aside, Global Defense is a great game, one of the closest coin-op conversions yet, and hopefully the forerunner of even better console games.

SDI is a quality game with a good feel and enough action to keep you away from the TV. Firing into a cursor takes alittle getting used to but when you do ...

SDI est un jeu fort bien réussi qui saura séduire les amateurs du genre.

It's all a bit like an updated version of Missile Command, and while it's not particularly addictive or attractive to look at it's a fair buy for four quid.

Doch das gute Spielprinzip läßt die Schönheitsfehler schnell vergessen. Auch wenn die zwölf Level recht ähnlich sind, gefällt mir SDl recht gut. Vor allem der Team-Modus sorgt für Unterhaltung (manchmal auch für Zwietracht). Wer rasanter Action nicht abgeneigt ist, der sollte sich SDI

Not a bad little game and what's there is very enjoyable. I wouldn't fancy its chances with a die-hard shoot 'em up fan though, it's just too easy. If your looking for original game play something like St Dragon
meets Missile Command
then check this out.
Graphically SDI is good, the nicely drawn monochrome sprites zip around the screen and you need a keen eye to shoot them. But sadly the gameplay isn't quite up to scratch. Initially fun to play, SDI soon slides down into the dumper because of its repetitive nature.

Insgesamt gesehen hat mich
SDI spielerisch überzeugen
können, da keine gravierenden
technischen Mängel aufzuspüren waren. Besonders der Titel-Sound hatte es mir angetan
(hardrockig und gut). Über die
Background-Story kann man
diskutieren. Aber: Was bleibt
ACTIVISION bei der Umsetzung
halt anderes übrig, als die SEGA-Story zu übernehmen?

Global Defense ist die moderne Version von "Missile Command". Mit Scrolling, einigen Extra-Waffen und guten Grafik- und Sound-Effekten wurde das ohnehin packende Spielprinzip gewaltig aufgepeppt. Und hier ist mächtig was los: Schon im ersten Level fliegen manchmal über ein Dutzend Gegner über den Schirm. Die ungewöhnliche Steuerung macht es einem Anfänger nicht gerade einfach, die Welt zu retten. Ich finde, daß Global Defense einen ziemlich hohen Schwierigkeitsgrad hat, solange man kein gewiefter Joystick-Profi ist. Aber man spürt, daß das Spiel zu schaffen ist. Deswegen ist Global Defense eine ständige Herausvorderung, zu der ich gerne öfter zurückkomme.

It's a jolly little blast with fairly good graphics and sounds. It makes a good first impression but I can't see interest lasting.

It's sounds like fun, and it is full of nice touches, but the only real snag is that it's all a bit simple, monotonous and dated, even thought it's only 2 years old. Perhaps I'm having a bad month or something, but although this was fun for a while, I'm afraid that even if it asks nicely, I can't give it more than 64%.
The Strategic Defence Initiative was Ronald Reagan’s attempt to solve the world’s nuclear dilemma by building more nuclear weapons and putting them into space. No, it did not make any sense to me either. I always knew that bloke was one sandwich short of a picnic.
In typical paranoid American programming style, those darn baby-eating Soviets have launched an all-out nuclear attack on the innocent western world. Sigh. As you happen to be in orbit around the earth at the time, the onus is on you to prevent global catastrophe.

Global Defense is good fun to play but it's standard arcade fare and suffers in the lasting interest department. You'll enjoy having a good blast every now and then, but it won't grip you or keep you enthralled for long spells at a time.

If you like fast action shoot-'em-ups this will prove a very worthy addition to your collection. But if you prefer to have some strategy element to your games you might wish to think twice before you buy.
ZX SpectrumYour Sinclair
All this is very straightforward. A simple rejuvenation of the Missile Command game, with a few extra pixels added for old times sake. The lure of extra levels, foes and difficulty creates an incentive for a couple of games, but it lacks that magical programming sparkle to make the attraction last any longer.

The end of the world is nigh! Well, it is unless you and your laser-armed SDI satellite can annihilate all of the enemy missiles streaking towards friendly territory. SDI is a conversion of a startlingly boring Sega coin-op, and this game simply fails to strike home in the entertainment stakes. I can't really recommend this much at all I'm afraid.
Mixed opinions here - it's all a matter of taste. But if simplistic shoot 'em ups appeal to you, you'll probably like it
SEGA Master SystemThe Video Game Critic
The graphics are nice, and a different planet is featured in the background of each stage. The space shuttle that picks you up after you complete a stage is a nice touch. The background music has a computer/space theme, and it's not too annoying. Global Defense isn't a classic, but it's fun to play for a while.
AmigaThe Games Machine (UK)
Taken from the Sega Global Defense, SDI boasts impressive graphics and professional presentation, but this does little to disguise the thin and repetitive gameplay – something it has in common with the ST version. In fact the major differences – as is so often the case – are to be found in the in-game tunes and sound effects. Little more than a modernised Missile Command, SDI looks good but doesn't taste the same.
Commodore 64The Games Machine (UK)
The Commodore version fares a lot better, with neat backdrops helping to boost gameplay. Without the coin-ops gloss the similarity of each level brings very repetitive play with it, especially on the Amstrad and Spectrum.

SDI tries to hide its repetitive gameplay with superb graphics, a mixture of average tunes and professional presentation.

Uno shooting game sicuramente atipico e da provare nonostante una realizzazione che lascia a desiderare. Se avete amato giochi del passato sullo stile di Asteroids potrebbe piacervi sicuramente.

A conversion of the mediocre Sega coin-op. Planetary defence is the name of the game as you fire your laser satellite at the marauding nuclear warheads. SDI is a simple game that was average on all counts when it was first released for £9.99. There are much better budget arcade conversions available for the C64, so keep well away from this effort.
Commodore 64Commodore Force
I find it tedious, dull and naff. At no point during play, does the shoot-em-up action of SDI rise above mediocre. I never realised nuclear war could be so yawn-inducing (sigh).

Un programme assez décevant, bien inférieur aux niveau général des jeux de la console Sega.

Para defender o sistema solar, você começa com três satélites e consegue alguns de apoio. São eles o P de cor amarela, que dá maior velocidade, o P branco, que vai apagar cinco das unidades do medidor de danos, e o P cor-de-rosa, dando maior campo de ação ao canhão a laser.

In conclusion, I'd have to say that at this point I'm not really entirely sure if this game deserves a look, even for SMS fans. It's okay I suppose, but with other shooters for the system out there like Sagaia or Power Strike II, I don't really think you'd play this too often considering all of the aforementioned problems. It's not the worst, and it is a bit unique, but it would have only made its mark had the programmers spent more time on the actual play behind the controls or basic elements and fixed the manual, the bastards. It's almost like they did a bit with this title, said "that's different" and then "screw it, we're done."

The Amstrad game suffers very badly with less colour than the Spectrum version.
