Would a rose by any other name smell as sweet? Apparently Roklan was willing to bet the answer to this timeless question was an emphatic Yes, as they developed this blatant clone of Atariís Asteroids. But is there more to Rockball than meets the eye? Read on to find out.
On the surface, Rockball would appear to be one of staggering number of Ďme tooí Asteroids clones that appeared in arcades and on home consoles in the early 80ís. The concept of copyright infringement was still a foreign concept when it came to computer games, so clones ran rampant. While it is easy to dismiss Rockball as one of these clones, there are a number of interesting innovations if one takes the time to dig a little deeper.
The first change Rockball made is that the asteroids are now, say it with me, rock balls! Each rock ball is composed of three layers in the form of color circles. Each time you shoot one of these balls, the outer circle disappears and the ball splits into two. The screen can support a surprising number of these balls with a minimal amount of flicker (although they will eventually overwhelm the processor causing flicker and slowdown).
change is actually a new feature that improves on the gameplay
instead of merely changing it. At the start of each of your
lives, a rectangle (protection box) will appear before your ship
warps in. If there are any asteroids (err rock balls) in the
protection box your ship wonít appear until the coast is clear.
This welcome features eliminates the cheap insta-deaths that
occasionally occur in Asteroids. Unfortunately this means
you may have to wait a bit before the screen clears enough for
you to warp in. This becomes more a problem at the higher
Finally we have the small addition of boundary walls. Both the playerís ship and bullets will bounce off the sides of the screen during the game. The rock balls however pass right through the screen boundaries, just like in Asteroids. This is a small but welcome change as it makes it possible to bank shots. However this also means that you can now accidentally shoot yourself, so be careful.
According to programmer Anthony Weber Rockball had one more feature that would make it different from all the other Asteroids clones out there: Gravity. Occasionally a gravity force will appear and pull your ship towards the center of the screen. If your ship gets sucked in it will randomly appear elsewhere on the screen (including right on top of a rock ball). This is equivalent to using Hyperspace in Asteroids, but the player has no control over it. Unfortunately the only version of the game to have surfaced doesnít appear to have the gravity force coded yet.
Although it may look like an original programming effort, Rockball is actually a port of an Arcade game. Anthony was shipped the internals of the arcade machine to study while programming the game, but it appears that much like his port, the arcade game was never released. Itís not hard to see why as Atari was starting to become more litigious during this period and probably would have squashed Rockball before it had a chance to sell.
