Set in the year SE 3256, the player is thrust into mankind's first interplanetary war between the Earth Alliance and the Ares Confederation. As the promising captain of the experimental dreadnought prototype, codenamed Sierra. Your sole objective is to help turn the tides of the war, utilizing the ship's advanced combat systems, flexible energy allocation and optimized platform deployment capabilities. To the captain, the core principles of prudence, guile, resource management and patience are essential to survival. The technology incorporated in Sierra allows it to explore multiple paths to victory: evade and assault enemy ships in classic broadside warfare; research armaments and upgrades to outgun the enemy fleet; or outnumber them with remotely-controlled weapon platforms. Rout the enemy’s armada in order to quell the rebellion and save Earth from the corrupt colonials.

I cannot get it to run. First I get the error there is no suitable graphics card. Then it tells me it requires pixel shader and (I am blanking). Then it crashes. Any ideas?

Hmm, can you tell me what is your video card? This error usually happens if the video card of your current setup does not have at least pixel shader 2.0. ( A requirement of the XNA framework)

I am trying to play demo version. I only get blank screens during tutorials (with "Next" or "End Tutorial" button on lower right of screen). I can't find any other instructions or even get to the options to set up the controls. If I could find that at least I'd know what controls/commands I'm supposed to have.
Thanks,

That's odd, the tutorials are supposed to be video encoded in wmv format. The reason why you're getting blank screens is probably a video codec problem of some sort. Try updating your windows media player/video codecs to see if it helps. The controls are fixed so you unfortunately can't set up the controls. Other than that, you can try to play the tutorials inside the Content/Transitions folder on your favorite media player its numbered sequentially so you should have no problems. If all else fails I can give you a rundown of the controls in text format.

Hope it helps.

Hey,
Thanks for the help. I'll try opening the vid's with Zoom Plyr. Are the controls fixed on the full game too? Or just the Demo?
Don't worry about answering right away. Just got the original Deus Ex ($2.49 on Steam this wkend only).
Just wanted U to know that your Human (I'm assuming) response/interaction is greatly appreciated. IIf half of the games on desura are equally supported, I'll be buying a lot more games here instead of steam. (I AM cheap. I mostly buy games < $5 or $10, so it's not a big win 4 U.)
But Thanks, Anyway.

Just to clarify things is the version of the game on desura 1.0b? Also, which error file did you opened? the one located in the mydocuments or the one located in the content folder?

empty one was game folder, i find the one in my document just said, the error look like it missing the shipdata file in my document. look like when installing via desura it dont install shipdatafile in mydocument.

Its probably because the savedata folder in the mydocuments doesn't contain the shipdatafile but has the folder itself. I have just tested it now deleting the whole savedata folder should resolve this problem.
