Actually my points are completely valid if you think in proper context. In a science fiction movie you shouldn't question how things are done because it is fiction there are aspects that go against physics but we take it as a different place than reality. Star wars is a fantastic example of how we could examine some and destroy it by using facts, but instead we allow ourselves a disbelief for enjoyment. The at-st walker is something that could very easily be in the realm of possibility but physics dictate that as it was seen it would not work, there was no counter balance to allow it to walk. But when I watch star wars I ignore that because it is science fiction not science fact. A game such as this can take something from reality and alter it however they please because it is fiction, a fantasy game that only has a slight basis on reality. I am an engineering student and a huge gun nut, I could allow all this to bother me or I could realize it is science fiction set hundreds of years in the future and know that perhaps there is more to guns in the future than there is now. Remember if we would have told people 600 years ago what weapons we are firing now and how they would we would have been burned for witchcraft. Theories of science are constantly changing, thus they are theories and not law. What's to say in the future they don't make projectile based weaponry that's entirely different from now. To recap it is science fiction, just go with it not being science fact. Also it's the future, don't base how it works on weapons from today.
