Gameplay
Terra I supplies the Zenbar crystals that provide most of Earthās energy, but its computer has been sabotaged and its own robot defences now help a band of space pirates. A counter shows your distance to the planet, and every 10,000 light years brings a new wave: a meteor storm, pirate cargo ships guarded by fast fighter saucers, robot interceptors, and finally fish-shaped devices that send glowing force fields towards you.
To clear a wave you must destroy everything in it without being hit. If you are hit you lose a shield and the wave starts again. You begin with five shields, one in use and four in reserve, and earn another for every 10,000 points.
| Target | Points |
|---|---|
| Meteor | 125 |
| Cargo ship | 225 |
| Fighter saucer | 275 |
| Robot interceptor | 425 |
| Fish force field | 650 |
Missions
There are ten missions. Mission 1 is the full journey to Terra I, and missions 2 to 5 each contain a single wave, which makes them good for practice. Missions 6 to 10 are the same five for two players working as a team. One player moves the ship horizontally and the other vertically, and control of the guns switches between them every two seconds. The difficulty switches have no effect.
Tips
- Watch the saucers, not the cargo ships. The cargo ships are slow and fly straight, but the escorting saucers speed off in random directions.
- Get close to the fish. The only way to stop a force field is to fly in and shoot the fish-shaped device that makes it.
- Donāt let anything slip past. Escaped enemies return, so a wave only ends when every target is destroyed.
