so yeah halo is huge and mainly due to the story and the artistic creativeness involved throughout the game. so i was doing some research work and came across this pic of a german cannon mounted on a train and then drew the similarities to the halo pic of the vehicle. who knows they probably have nothing in common at all to the designers of the game but to me they have a small similarity. the tank train is great because it would seem that if the turret turned to either the left or right of the train and fired it would de-rail the entire carriage. impracticle but cool and thats something that designers must think about is whether or not their design is practicle or whther the point of it is to be darn crazy.
