Each time you shot a meteor it divides into two smaller pieces (until pieces are too small to represent a threat).
The objective is to score as many points as possible by destroying meteros (asteroids). The player controls a triangular-shaped ship that can rotate left and right, fire shots straight forward, and thrust forward. Spin your ship around and blast passing space rocks with missiles before they collide with you.
If you have over 25 years chances are that you've played some version of "Asteroids" when you were "young" :)
Delphi XE ships with an Asteroids clone called "DMeteor".
The source code to "Delphi Meteor", can be located under the "C:\Documents and Settings\All Users\Documents\RAD Studio\8.0\Samples\Delphi\VCL\Meteor" folder (on a default Windows XP install).
By exploring the Delphi Meteor source code you will learn how to program:
There are a few more games that ship with Delphi under the "samples" folder.
