Get the update to 2.0.0a.
AA is playable with modem and is an AWESOME FPS shooter based on the latest UT engine. Yes, its multiplay online only.
The graphics, particle effects, etc. are good.
Check out the Videos the Army made for this game which includes Special Forces footage mixed with game footage:
Click Save As and download these:
AA Special Forces "Fast Trailer" 26.5MB
AA Special Forces "Slow Trailer" 26.5MB
They are different trailers with different footage and different (fast and slow style) music.
For new players, I recommend after you go through qualifications; open a map you want to play without connecting to a server and explore around so you know the map(s) so you don't look so much like a noob and being lost.
To do this, bring up the console with the tilde key (~), and type "open bridge_se", or "open sfcsar" for example (without the quotes of course).
Then at the console type "playerlock 0", to unlock, then you can walk around.
There are alot of other commands you can experiment with (when not connected to an online server), find them on the
http://www.americasarmy.com site, probably in the forums.
BTW, This games developement is funded by the US Army till 2007 I do believe.
