Chip Defender

Chip Defender is a tower defense game by Zanarotti Michele built with JavaScript, jQuery and the HTML5 audio and canvas elements. For those of you who haven’t played a tower defense game before, the idea is to try to stop waves of enemies from crossing the map by building towers which shoot at them as they pass. When an enemy is defeated the player earns money or points, which are used to buy or upgrade towers.
Canvas is used to load and rotate images, draw progress bar and arcs, paths and for some of the effects.


Zanarotti has made the project available as jsDefender on Sourceforge. The project is themeable and can be configured by XML to make your own tower defense game.

Doesn’t seem to work in Firefox 3.0.6

@Levi Aho
Firefox 3.0 was not ready enough for canvas element. You can eventually find the way to get it working, but the minimum requirement is to have firefox 3.5 or more (for almost all canvas demos ), chrome 3+ or opera 10+ (ehm… here i have to work on some graphics issues).

I cannot understand your problem. What browser and version are you using ? FF3.5+ and Chrome5+ are OK.

On OS X 10.5.8 and Chrome 5.0.342.7 beta, works great. Highly addictive game – on stage, the doomed core (hard), got to wave 100 with one 2 enemies left but didn’t have enough points to take the the last hit.

Working on Opera 10.54 Internal: thus I didn’t get how the game work (place the chips then click on enemies before reach the red ball?

@Ylon : the chip will act against enemies without your intervention. Probably the enemy is too far for the chip shoot range at his actual level, so the chip is not shooting. You have to level up your chips. (You can find information about tower defense games in many sites).

Dude, the buffering before weapon placement is BS.

No matter if some one searches for his vital thing, so he/she needs to be available that in detail, therefore that thing is maintained over here.
