About JavaScript-Invasion:

This is the cross-browser version of the original "JavaScript-Invasion".
"JavaScript-Invasion" was designed as a demo-page for an advanced employment of JavaScript animation techniques. The first version (for Netscape Navigator 3.0) was published in January 1997. The cross-browser version with advanced game play was published in July 2004.
The game is pure JavaScript and does not use any plugins or other extensions!

 
How to Move:

Keyboard control: 
Use the cursor keys, the numeric keypad or the alternate keyset to control the ship.
(Mouse-control is still active.)

Scoring: 
25 points for every invader, 1 per bomb, 200 per level, and a bonus for each new wave.
By the way: Following to what seems to be a convention in other invader games, you are only allowed to shoot four shells at a time.

 
Smoothness: 
Animation quality depends on the hardware used. Increase smoothness on faster machines.
(Settings: 4 steps: low quality [default] ... 1 step: high resolution.)
