Mechanical? As in, what, a machine or robot? I'm not saying to take the article as fact, but these clicking noises and, specific to the bullet ant, the shrieking before it attacks have been documented and sounds like exactly what is going on at the end of the teaser.
And again, fungus-infected, mutated humanoids are ok in this "touching human story" but ant monsters are completely out of the question?
It's not necessarily about the opening of the teaser where the ant is shown being infected and killed by the cordyceps, nor is it about proving anything or throwing it in your face, but it's more about the second half of the teaser and why it was include and what exactly is going on? The theory I thought most others agreed upon is a person being stalked by some sort of ant creature. If not that, then what is your stance on the whole thing?
Edit: Maybe you could possibly clear it up, arne? Would it be too much of a spoiler if you did? :-/
