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!

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 ...

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.

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.

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.

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."
