Ha, that's all well and good, but if people don't know how to activate the feature, then it's pretty useless. And as mentioned before, there's no advantage to playing in 3rd person, and it's not all that cool after a while, so it's a tiresome endeavor to uncover. And he could maybe just be joking, or even covering his a**, as usually he's pretty clueless about his own game.
Hi, I've experienced this a few times myself many months ago. I think it is just a bug that occurs, and getting to the bottom of it is not too important because there is no clear advantage to being in the third-person view. When the creator of the game said it was a "feature," I would be willing to bet that he didn't really pay attention to the picture, and just assumed it was a picture of a 1st person view. A feature wouldn't wouldn't be so convoluted to attain. So either a.) It's a bug that is unintentional, which is the most likely scenario, or b.) It's supposed to be a feature, but the way to activate it (for instance, pressing a button) doesn't function properly.
