--- title: Play with Giant Robots teaser: tags: news,web author: Tristan Dunn published_on: 2010-08-30 --- A few of us participated in the [Node Knockout](http://nodeknockout.com) this weekend. Our team built a [real-time, multiplayer tower defense game](http://piston-hurricane.no.de) named after this very site. We're all fairly new to Node, but it was a breeze working with [express](http://github.com/visionmedia/express), a Sinatra like framework, and [socket.io](http://github.com/LearnBoost/Socket.IO), a socket library with several transports for cross-browser support. The client uses canvas, CSS and JavaScript with some fancy graphics. We're really looking forwarding to working on it more after the voting ends this Friday. [![''](http://thoughtbot.com/images/td-grsiogr.jpg)](http://piston-hurricane.no.de) If you can find time between games, [vote for it](http://nodeknockout.com/teams/piston-hurricane) and the [other awesome entries](http://nodeknockout.com/teams). And if you participated this weekend in an attempt to win [some awesome gloves](https://thoughtbot.com/blog/post/816267526/rock-em-sock-em-robots) let us know what libraries you used.
