The Badstar Empire is on a mission to subjugate the people of your world, but a counter attack has been organised; the first wave of this assault is to do as much damage as possible to the little Badstars using a small but manoeuvrable spacecraft armed with lasers for airborne enemies and missiles to destroy the ground-based defences. The cassette inlay comments that this super secret project has been given the codename ZTB – Zap The Badstars… and yes, that’s deliberate because the original name of Paul ““Spindizzy” Shirley’s hardware scrolling 1986 blaster was ZTB, which in turn is short for Zap The Bastards.
The gameplay in Mission Genocide for the Amstrad CPC is fairly traditional scrolling shooter fare, using a fairly rarely employed feature of the CPC hardware for scrolling – similar to the technique used for the excellent Firetrack on the BBC Micro – and some neat tricks to speed up sprite rendering which keeps things very smooth and responsive. The ship is simple to control but rather cleverly puts two weapons onto just the one button; holding fire down shoots the main guns at nasties in the air – pressing space will toggle a handy automatic fire option – whilst missiles are launched when the button is pressed after being released.
There’s a power-up system too, with items being found in storage silos after they’re destroyed along with blobs of Astro Gloo which are needed to actually stick said items to the craft. Just grabbing everything uncovered will rapidly backfire however because, if the player accidentally picks up a black hole, said adhesive loses its stick and the previously collected toys are lost. The other item to keep an eye out for is the shield which is incredibly useful , especially when things get busy around the third stage – rather subtly called “Taking the Urineium” – where the ground bases start getting more enthusiastic about firing back.
Mission Genocide is on a couple of other platforms but didn’t have as much impact there as it did on the Amstrad CPC; the Atari ST version is much of a muchness that doesn’t really take advantage of the hardware and the C64 version didn’t make much of an impression in part because there were a lot of more accomplished scrolling blasters around when it arrived in 1988. If you think I’m perhaps being harsh there, Paul Shirley himself has previously described the C64 conversion as “not worth the tape it’s saved on”. But the Amstrad CPC version is solid stuff and, when our trusty CPC464 has been set up in the front room and left running in the past, it’s usually Mission Genocide that’s loaded into it.
