Really enjoying Brink, completed it on Normal with little problems and thought whilst PSN is down have a go at Hard, well I breezed through Resistance and was thinking this isn't too bad, then I played Security on Hard and finished day 1, but now I am really struggling on the second one where you have to deliver the code. There was 5 of us running to the station and I thought we have got it in the bag here but the buggers just wasted everyone when we got there and I got the green circle halfway and someone killed me. After that no chance.
I played the next day and same thing, got to the sample and could we hell deliver it.
Not complaining but I seem to have come to a sudden halt at this point and no progress is occurring.
Any ideas?
Hopefully playing online soon so it just might never happen for me.

Just curious, what level are you? As many others have said, as you gain in levels the Bots scale in difficulty (which is pretty crazy once you get past like level 12).
