concept is revealed at the first of the maps terminals.
Apparantly, you are on board a special military facility attached to the earth by miles of cable. It soon becomes clear that the facility has been converted into a museum of sorts, in which actors and robots re-fight a famous battle. What makes it so interesting is the Physic Model that comes with the map. This makes you invincible so that you can walk through the battlefield unhindered. Also, the Pfhor now make a 'clunking' sound when you hit them, showing that they are robotic imitations. This ride would be a 5 star attraction at Universal Studios....
There is also a 'secret' terminal that explains the map's origin, and the name. Nice touch :)
Without a doubt, ThroneNet is one of the most original maps of all time, and combines the many mirid traits of a good map into one, enjoyable experience. 5 dead BOBS in my book any day!
