One other thing though, the missile objects look a lot smaller than seen in Thirdspace, with a pointed tip instead of a rounded one. When the weapons explode, the explosion seems a bit small. All in all, this game is defiantly on track and follows the show faithfully. The few cut scenes I saw were enough to convince me that there is a huge dynamic plot. I recall someone mentioning that in a single run through of a game, you may go through twenty missions, but this leaves out another 80 or so that are written in.
Every mission is truly unique, because of the random element to the game.
As for demos, the developers are planning to have them. However, they will be pretty simple and pretty much like the E3 build. A couple of the developers explained why. The game is very complex in storyline and game play. But giving it a very limited demo teases the fans, and attracts new fans to the game.
