You are appearing for a TV show where you have to defend your home from a whole host of enemy robotic craft. Well, that popular TV program which is seen by all population from all over the galaxy is produced by the Ground Defense which combines the politics that the networks wanted to advertise, and the hardware to show of the military's might. The show is taken in an arena in which spacecrafts are fighting and certain ships leave behind energy pods, turbo boosters and shield enhancements when destroyed, which you can collect by simply flying over them. As it's a TV show the better you perform and the more dramatic your performance is determines marks what type of ship you get in next round! There are several ground installations too, and the computer controlled drones are attacking in hordes. Some of the ground installations are your, so you need to protect, some not (so you need to destroy). You may choose which craft suits you most at the beginning of the game, and any of these is equipped with sophisticated instruments such as radar that depicts in different colored dots the attacking drones and enemy or friendly installations. Do not forget to collect the pods found when drones are destroyed as they can prove useful to your craft to help you combat with the drones.
There are 50 levels in all, spread across five different planets. The controls are a little bit awkward but you soon get the hang of them, and the option screen allows you to perfect the mouse sensitivity to just how you like it. So take your time and you might just win the supreme accolade of Defender of the Ground!
The Atari ST version offers a nice and fast moving 3D environment (a bit faster that the Amiga version) that certainly keep the game alive. Crafts move fast without any scrolling glitches. Each planet offers a few details though, and it’s a shame there isn’t a bit more variety in the landscapes. Still look colorful and satisfactory.
The sound is ok, offering plenty of SFX (but not sampled, only found in the Amiga version) which are pretty good and seem to go well with the game.
