The year is 2052 and a giant energy shield has been created around the earth to protect it from alien invasion. The shield is powered by generators scattered around the earth, and can protect the earth from large warship. But now there is a new threat, an alien race is invading the earth, they have sent small ships that can penetrate the shield to destroy the generators. Only you and your low level fighter ship can stop them. To complete each attack wave you must destroy all alien ships. Each time you destroy an alien ship with your laser a power up will appear. To fire a missile you must first obtain a missile lock. To obtain a missile lock point your ship towards the alien ship you wish to fire a missile at. The crosshairs will change colour to red. Whilst the crosshairs are red you can fire a missile. The crosshairs will turn yellow whilst there is a missile in the field of play. Firing your afterburners will increase your speed, but will reduce your fuel. The ships fuel is only used for the afterburners so running out of fuel means that the afterburners can no longer be used until the ship is refueled. There are four types of alien ship distinguished by colour: Red/Brown - These ships fly over the generators and destroy them. Once the ship has destroyed a generator it changes colour to green. If there are no more generators left the remaining red ships change colour to blue. Green - These ships only attack your ship. Purple - These ships attack your ship, but if you get to close to them they will become invisible. Blue - These ships will just try to ram your ship to destroy it. |
