QS Defender
Description
QS Defender is a side scrolling shooter that although it is inspired by it, lacks many features of the arcade game Defender. This version is constantly scrolling left to right and there is no option to turn around and move in the opposite direction. The player can move up and down, fire and use thrust to increase the movement speed forward. There is only one enemy type and each one killed is worth 100 points. Enemies appear in waves. At the start there are just a few but as the player progresses it gets more hectic with up to eight enemies on the screen at once. The player has nine ships. When getting hit the screen goes black for a few seconds before it starts again with a clear screen and one ship less. Once all ships are lost the game has to be restarted through basic.

If you think the ZX81 is incapable of scrolling, then you thought wrong
The Good
Defender was a popular arcade game released in the early Eighties by Williams, and official ports and clones were released on popular systems at the time. Sinclair’s ZX81 machine missed out on one, probably because developers thought the machine couldn’t handle the frenetic gameplay that it had. Quiksilva, a small British company, did a half-baked version that was originally called QS Defender. Williams objected to the name, so it was re-released as Defenda. In Quiksilva’s version, there is no such thing as a radar, nor are there any humans you need to rescue. Furthermore, enemy ships are represented as a simple Basic character.
To make up for these shortcomings, you can purchase a sound generator from Quicksilva themselves that will give you little explosions when you shoot down enemy ships. The wind effects sound fantastic. The scrolling is impressive, and it shows what the humble ZX81 can do if programmers put enough effort into their work. I like the way the game gets difficult as you progress. This is evident when you face only one enemy ship at the start, but face three or four at a later point. One thing I really like is that if you move your spaceship while shooting, it leaves a trail of bullets behind, making it easier to kill enemies.
The game awards you with nine lives, which is probably a more than enough reason to “score attack”. It is programmed in Basic, and anyone who is familiar with the language, can modify it for their own personal use.
The Bad
The game lacks a title screen, and you are kicked to Basic after you have lost your lives.
The Bottom Line
QS Defenda may be a half-baked version of Williams' classic, but that is understandable given that the machine that this game was designed for had very limited hardware. The ability to use a sound generator makes up for the missing mechanics, and it shows people that the ZX81 was actually capable of hardware scrolling. It would have been nice if there was a title screen, which you go back to if you run out of lives. Other than that, this is a very good Defender clone ZX81 users should be proud of.
