49) Q: Is there a way to tell if a Alien Artifact has been connected to a network node? I find it a real pain not knowing which city to send an artifact to.
A: There are two ways:
With the Alien Artifact the active unit, press {G} (go to base). The list that appears is all of your bases (and your pact-mates') on the same landmass (or on the shore of the same sea if aboard a transport, in which case the transport must be the active unit). Any with an Unlinked Node will be so indicated, and you can easily select where to send the Alien Artifact. IIRC, if you built The Universal Translator, it, too, will be indicated.
If your monitor resolution is 800x600, you can look at the facilities listed in the Base Operations Status {F4}. All (linked) nodes will be so indicated.
