I tried this last night loading up Rally point Bravo. Blew up 4 tanks and no cheevo. Is it not possible to do this by leading up the second rally point?
I’m pretty sure you can do it from the Rally Point. Did you do it on Heroic?
I did it on a legendary run.
I don’t think that it matters where you start from though, and difficulty must be whatever the achievement say it has to be.
Was it on Heroic or Legendary?
