http://www2.rasterwerks.com/game/phosphor/beta2.asp This is a very amazing Shockwave game which is a first person 3D shooter that runs entirely in Shockwave in your browser. This game is a beta, and is designed to be played against other people (I won't show you how to set that up). If the software says it needs to install something for this video, it's probably a good idea to go along with it. Mac people need to go into the video settings in the preferences and change the graphics mode to OpenGL from DirectX.
