For those who enjoyed the fantastic graphics and gameplay of the first one, here is the page where you can download the 230MB demo of the second. Although the page is in German, Google does a pretty good job of translating it.

This version contains the Intro in original quality and the complete first chapter of the play. Altogether seven missions are available in the Story and a mission with the single missions. The size of the Downloads amounts to 380 MT .

There are also some screenshots and an intro that you can download. From the looks of the screenshots, the graphics on this one might uphold Aquanox's reputation as being the cutting-edge of what games are capable of showing. At least until Doom3 and Unreal II come out that is.

Interesting to note that multiplayer is listed as not being supported. Those of us may remember that this was a problem with the first Aquanox as well when it was released.
