Turn your neighborhood (or anyplace else) into a Tower Defense game with Google Maps and MapTD

The Verge - MapsTD adds tower defense to Google Maps

"Remember the 8-bit version of Maps that Google "announced" for the NES this weekend? April Fools' Day is over, but Duncan Barclay's MapsTD has put it to use by adding a simple tower defense mechanism that can be played anywhere on (or even outside) Earth. After you enter a location, MapsTD will spawn a path to defend and give you £200 to spend on towers with simple range, speed, and damage attributes.

It's not a particularly complicated game, and we haven't yet found much of the enemy and tower variance that's available on other web defense games. The conceit, though, is pretty clever, and it uses the various Maps overlays to great effect. ..."

MapsTD 

This game was made by Duncan Barclay (dro.me.uk).

MapsTD relies on the following code:

• Google Maps API
• Mootools
• Page visibility code by David Walsh
• Tony Haddon's Google Maps marker image (used on Facebook and Twitter)

Special thanks to everyone who helped test MapsTD, and balance all the creeps, towers and levels.

Now that's an awesome map mash-up! (and one that's eaten too much of my time today... ;)
