My least favorite part of the whole mission was in the beginning how the vanguard didn't detect any of the cabal ships earlier. I mean, we have millions of guardians traveling throughout the solar system plus outside allies who keep tabs on things. You would think the amount of ships that attacked would have been seen at some point prior to a "surprise attack" but instead it just paints the image of the cabal teleporting to earth and attacking the last city on earth. Also after the travelers light was drained from the guardian it was dumb he the character just sat there on his knees like if he was ready to suck a D for his life. I'd suggest having someone proof read the script because so far, this sucks.

Gary destroyed the Tower with ease....we are safe on the Farm.

It's really, really hard to create a plot hole within one mission. What we got were a -blam!-ton of unanswered questions, not plot holes.
