Well, this must be the one of a million game. I mean, the guy literally had luck with about everything that could matter for a speedrun. Where he landed at the first site, quite close to the UFO, aliens miss a lot, he does well. At the base the same thing: The position of the base near his own, the commander and leader damn close (hello? commander right next to him, just the right moment he needs it to be? not to mention one auto shot and the wall has a hole, I sometimes fired half a clip and nothing happened) and the aliens missing again, not pursuing or something. And then at Cydonia again starting right next to the elevator, starting right next to the brain, not being crushed by the Silacoid, not heavily mind-controlled by the three(!) Ethereals... In my personal opinion possible, but to good to be true.
