Help with Three Point Upload(A,B,C) objective on higher difficulties ?

I've been wondering the same thing. I don't think I've seen a successful wave 6 upload on gold yet against Kett or Outlaws. Between the Fiends/Wraiths and Krogans/Ad... Uhh, dogs, it seems pretty much impossible to keep them out of the circles. At least the Remnant aren't quite so bad - Breachers are the only units that suicide-rush you, and they go down easy.

I see three solutions.

1. Make the Cobra's actually kill things so that we can get Fiends and Krogans (and occasional Hydra/Destroyer) out of the circle.
2. Make it work like the hack so that it keeps going when enemies are in the circle.
3. Don't let the uploads reset, so that we can come back without having to start all over.

I think Zero/Wave 6 upload (you know which spot I mean - the one were you can't see enemies until they are about 5 feet away from the circle as they come through the back door to the building) is going to be the new Hydra/Wave 10 device on the crates...

On bronze, I actually enjoy the uploads, they were a nice new objective.  On silver, they are frustrating - especially against Kett.  On gold they feel damn near impossible.

Now, all that said, I find that the best method on Silver/Anything or Gold/Remnants usually seems to be splitting the squad between two circles, and then all four in the final one.

I feel like the Ascendants are the least dangerous enemy in the Kett faction, aside from the odd time I get stuck in a corner and can't dodge out of the sync.  Annoying, yes, but nowhere near as dangerous as Fiends, Annointed, or Destined.
