In our haste to get this build to you, we've left a couple of key points out. Here is some more information that wasn't included in the readme file:
Direct X 3.0 -- Is not included on this disk, but is required to run Uprising. If you don't have Direct X 3.0, go to http://www.microsoft.com
Calling in a perimeter turret is F5 and calling in a SAM site is F6. The Killer Satellite (KSAT) attack is not available in the demo, but would be F7.
Occasionally, on the Training 3 map, after fighting your first battle to the east and returning through the eastern gate, your Wraith will be blocked by an invisible barrier. To remedy this, turn right and drive into the water, then turn left and drive around the hill towards your Citadel.
