Other mistake: Gandu 3 Echo has initials on his sleeve which read G3A. This would be fine if he was Gandu 3 Alpha, but he's not (although he should be - see the other entry relating to him). It should read G3E.

Other mistake: When Lincoln and Jordan first enter the city, just before Jordan sees a poster of herself, in the background you can see two trains high in the air, with a skyscraper behind them. If you look carefully at the shadows cast by the two trains, one of them is completely wrong. The train that goes from left to right has its shadow trailing on its left side, and the train going from right to left has its shadow trailing on its right side. Irrespective of which direction the two trains are travelling, both their shadows should be trailing from the same side, as there is only one light source, i.e. the sun.
