Defender is Atari's excellent PC port of Williams' arcade hit - one of the most successful of all time designed by legendary Eugene Jarvis.
Your mission, as captain of the "Defender" ship, is to protect the humanoids stranded on the planet from their alien abductors. The scanner will help you determine a strategy to shoot down the alien ships before they reach the humanoids. If you destroy the aliens after they have captured their prey, you must return the humanoids to the safety of the planet or they will fall to their death. If an alien carries its victim out of your range, the humanoid will mutate, join the alien force, and take to assault with deadly vengeance.
Like the arcade version, the beauty of Defender PC is that challenge becomes ever more intense the more you play. You'll come across new, tougher enemies such as bombers, mines, and the cosmic "Baiter." The range of power-ups is also innovative for their time: you have a limited "smart bomb" power, and "hyperspace" puts you into an unknown space warp.
Defender is truly one of the timeless classics that is no less fun no matter how many times you have played it. A must-have, and an induction into our Hall of Belated Fame. If you like this game, also check out the less-known sequel called Stargate on this site.

my left eye hurts particulary because it
exposed it too much to the delicate red
hue of the game
I played this on my Apple IIc over 30 years ago.
One of the best memories of my childhood, playing Defender in the arcade. Still my favourite game.
not bad.
I remember playing this game as a kid, wasting all my pocket money in Game Saloon.
I think it's a very good game

Try setting Aspect=True in DOSBox options, that might do the trick. You can also try setting fullresolution=original and windowresolution=original
Otherwise check the DOSBox wiki, it's full of resources.
it does download on windows 7 home. got it installed, downloaded stargate and ran it, but the resolution (I think) is wrong I know it's a old game but even full screen mode is too big, rather the letters needs to be smaller, to fit correctly in dosbox window does anyone know how to do that?
I use to play this game when i was a kid. Best game in the world.
it doesnt download on windows 7?
