So while I was playing campaign Infinity, my game froze. When I got it back on its telling me to start campaign rather than continue. Does this mean I'm going to have to start over? Start the level over? Or can I start up from bravo and still get the achievement?
In game it shows I've beat the other levels. And this one has me at bravo which it froze shortly after. Waypoint even shows the 15 min in game on that level and the 60 or so kills. Its just the game itself didn't give me the option to continue.
If you've beaten the other levels, you should be fine starting at the mission where you glitched out. But I should point out that when I beat the game solo, I did not get the achievement. I had to do it again on co-op before it popped so there is some kind of weirdness with getting credited for your progress.
