Ugh, progress-halting bug on the 6th mission. At the end of the "Bullfrog" jetpack section, you have to clear a landing pad and two shade turrets are marked. I used the jetpack to get to the upper balcony of a building full of Brutes and walked around to the back, using an FRG to kill the turrets. Because Shades is dicks, right? Anyway, a Phantom shows up to drop off Brutes and jackals and I kill everyone. Nothing happens. Load checkpoint, repeat, nothing happens. I back out of the game, load it up, kill everything, nothing happens. Just a bunch of random civilians running into walls and getting stuck.

I figure it's because I killed the turrets before the phantom shows up and broke some half-assed script. Now I have to go back to Rally Point Alpha and redo the whole goddamn thing on Legendary. Rally Point Bravo picks up right after this part that won't advance.

Also, on my first Heroic run through, I got a checkpoint as I was sliding off a cliff into water. I'm still not sure how I pulled out of it. The previous checkpoint failsafe code wasn't kicking in, because I was taking too long to die. I watched Giant Bomb's video review and they showed a Warthog get a checkpoint as it was flying off a cliff. Embarrassing.
