How did I know that my lasers destroyed the Meteor?
I setup the lasers, power them over 10 hours, and than activate them in the computer lab - all works fine.
The laser shows a red beam going into the ground (Meteor on the other side of the planet?) - and if I now log in, i see some flaming obstacles in the sky for a short time....
is it done? the counter still count down on the info-page!!!! ;-)
