EDS Thrust
Microsoft released their XNA Framework beta at the start of September '06. This is a little blaster written to get the hang of the basics and 2D graphics support.
It's a one- or two-player Thrust clone. Instructions are on the title screen. Pick those containers up!
You'll need the XNA Framework beta installed to run this. Unpack the zip file to a directory, and simply run EDSThrust.exe.
Sorry about the size of the download - that's due to the size of the sound effects!
