You are in command of an SA27-3 terrestrial defense station, and are responsible for the defense of eight major cities from orbital bombardment.
The SA27-3 defense station incorporates the following special features, which are unseen in earlier versions.
* Multi-Touch Targeting - Shoot missiles from the air with the touch of a finger, just aim and shoot, or use up to four fingers at a time to adopt a spray-and-pray approach.
* Simplified City Status HUD - If the city is showing on the screen, it has survived. If it is missing, it has been destroyed. Simple.
* Unlimited Ammunition - The solar-nuclear reactor built into your SA27-3 ensures that you will never run out of ammunition, allowing any strategy to be employed in the defense of your cities.
* Efficiency Rating - The SA27-3 software tracks your efficiency using a simple scoring system. The more missiles that you destroy in a row, the higher your efficiency rating will become.
This concludes your briefing on the SA27-3, time to lock-and-load (pew-pew).
