The developers behind the GWT Java framework have implemented a port of Quake 2 that runs natively in modern Web browsers. It takes advantage of recent innovations in emerging standards-based Web technologies such as WebGL and WebSockets.
GWT and the Java-based Quake engine both had to be extended and modified extensively in order for the pairing to work, but the effort paid off. It serves as a compelling example of how emerging standards are becoming increasingly capable of delivering all of the necessary functionality for interactive 3D network gaming.
As some readers might remember, Google released a Quake demo for Native Client (NaCl) when the plug-in was first announced in 2008. The state of open Web technologies has clearly advanced since that time. It's no longer necessary to rely on plugins to deliver this kind of functionality.
