|Steve Baker programmed both
Defender and its sequel Stargate for the 400/800 and 5200
Stargate was the 1982 sequel to Williams' smash arcade hit Defender.
Stargate's name was changed to Defender II sometime after 1984 due
to some kind of copyright problem. As with most sequels, Stargate
didn't change the game formula that helped make the original game a hit.
Instead Stargate expanded on the formula...
Stargate added a number of new features to the Defender
formula including new enemies, new abilities, and of course stargates!
Stargates allow players to instantly warp from one area of the level
to another, which can be very handy if used right. Stargates can
also be used to warp forward levels if certain amounts of humanoids are
carried into them. The ability to score bonus points for carrying
multiple humanoids is also a new feature first introduced in this game.
Other new abilities include the Inviso power, which
is basically a super cloaking device. Using Inviso makes your
ship invisible and allows it to pass through all enemies and their shots.
However you can still shoot while "Inviso", so make
the most your Inviso time. Stargate also includes the ability
to enter Hyperspace. Entering Hyperspace is just as dangerous
as it was in defender, and while it can save your life in an emergency
it can also blow you to smithereens. Use the Hyperspace option
Stargate is unique among Atari 8-bit games as it uses
the original arcade title screen, including all the arcade colors, fonts,
and options. Of course all of this wasn't by coincidence, programmer
Steve Baker had an original Stargate arcade machine in his house so
he could perfect the 8-bit version. According to Steve
when he was done you could stand back 10 feet from the screens and not
be able to tell the difference.
The options on the title screen allow the player to
affect a whole range of game variables:
|Number of Players
||Pretty self explanatory. This can be set
to 1 or 2 players
|Number of Ships
||Another no brainer. This is the number
of lives each player has. The value can be set from 1 to
|Inviso Time Per Ship
||This option sets the amount of time your Inviso
power lasts. The value can be set from 4 to 20.
|Extra Ship Every
||This option allows the player to set the frequency
at which extra lives are awarded. This value can be set
from 1,000 to 50,000.
|Men Needed To Warp
||This option affects the number of humanoids the
player needs to carry into a stargate to warp to the next level.
This value can be set from 2 to 9.
|Last Wave Warp Allowed
||This option allows the player to set the last
wave number in which the wave warp (mentioned above) can be used.
This value can be set from 10 to 99 (hey you don't want
to skip all the levels do ya?).
|Master Control Difficulty
||This option controls the overall difficulty of
the game. The value can be set from 1 to 5.
While Stargate may have beautiful graphics and an arcade
accurate title screen, the only known version has massive slowdown problems.
When too many enemies get on the screen at once (which is often)
the gameplay becomes extremely choppy. According to Steve this
is because Stargate used all the Atari 8-bit's processor due to the
variety of graphical techniques used (Hi-Res, Bitmap, and Player Graphics).
Although Stargate never achieved the same level of success
as its predecessor, it shows that even a great game like Defender has
room for improvements. It is unknown why the Atari 8-bit
port was unreleased, but the 5200 version also met a similar fate. I
guess the collapsing market just couldn't wait for quality arcade ports
to be released.
