Game is great! Super in depth and faithful to the original. I even tried to do the "Megg" Easter Egg, and it kind of worked. I could kill Captain Keyes. The Invincible Marine did spawn. I don't think the easter egg is in here, seeing as there's no door. But what did happen is that I was able to walk through the wall in front of Keyes, even before killing him, and after evading the Invincible Marine, I got stuck in a loop of Chief walking off the side of the screen and reappearing on the other side without touching the controls. Not complaining to be clear, it was cool I was able to get that far in the first place. Can't wait for more!
